A B Gentles

Introduction

This test script aims to exercise the Forth Autoguider in all of its configurations.

Each operational command is not tested in all modes but all the generic functions are tested and then the normal operational sequences confirmed for each mode.

Equipment needed

Preparation

Connecting the VME console to the terminal or workstation.

The console port is round the back of the VME rack. it is a female 25 way D type located next to the 50 way parallel cable connecting the disc drive to the VME rack. There is a label "CONSOLE", the port is in between the CONSOLE and SASI labels.

Connecting to a terminal

A single blue cable will connect the console port to a terminal. Set the terminal to 9600 baud, 8 bits no parity.

console                 terminal                 signal                   

male                    female                                            

2                       2                        txd                      

3                       3                        rxd                      

7                       7                        ground                   


A prompt should appear if you press return.

Connecting to a Sun workstation.

SPARCstation 20's have a single 25 way female D-type connector round the back of the workstation box labelled A/B. SPARCstation 5's have two 25 way female D-types labelled A and B.

Use the A socket or the A/B socket.

A Green cable and a Red cable in series provide the correct connections.

console                 Workstation              signal                   

male                    male                     -                        

2                       3                        txd

Open a terminal window to the port with the Unix command

abg@Varda> tip /dev/ttya -9600

Note that if you get an error message of "All ports busy" there may be another tip session accessing that port. In the unlikely event of no other tip processes running then the low level serial i/o process may need restarting. This has to be done by rebooting the workstation...

Connecting to the NIU in the RGO computer room.

This connection is done via the RGO fibre optic building links.

Note the handbag links in the serial transceivers which set the connections for pins 2 & 3.

Oscilloscope and CCD camera

Setup the oscilloscope and camera head such that the oscilloscope screen is imaged in the centre of the CCD image.

Turn up the graticule scale and start the Autoguider framing with CASS and TV ON commands.

Setup the zoom lens so that the oscilloscope screen fills the ccd window vertically. If this is not possible then make the display as large as possible.

Turn off the graticule scale and put the Oscilloscope into XY mode, move the spot into the centre of the screen and turn the intensity down until the spot is quite faint, but focused.

Focus the lens to get the sharpest spot on the AG display.

Signal generators.

Connect the general purpose signal generator to the Y channel

Setup the Y channel to have a fast square wave, > 100 Hz. Adjust the amplitude and X channel scale to produce two spots, one above the other, about one half a graticule square apart.

Connect the VLF generator to the X channel.

Logging output from the Autoguider console.

The console terminal line is connected to a SPARCstation, currently Varda /dev/ttya. It is possible to connect a program to the serial line with the standard output and input connected to the Forth system. A program agseq has been written which will take an input script, pass these commands to the autoguider and log the output to a file. To start this, issue the following keystrokes:

<cr>~C

You will be prompted for a Local Command and give the command to run the agseq program.

Local Command: agseq testscriptfile logfile

A copy of the program can be found in /home/ao/abg/ag/

The syntax is agseq [cmdfile [logfile [ -v ]] ]

If the log file is missing the command filename has the last 3 letters replaced with log

If the -v option is used, the output from the Autoguider is echoed to the screen as it appears.

If no arguments are given the default files agtest.com and agtest.log will be used.

Command wrappers to save typing

A series of ICL aliases have been defined which wrap the AUTO SEND OBEY syntax into a single 3 digit command with the same name as the Forth system word or UtilNet command to make running the tests easier. WHT-AUTO-1 lists these synonyms.

These can be loaded by typing

  1. WHT_AUTO_DIR:AUTO_TEST.ICL

at the ICL> prompt.

Autoguider Commands to aid making measurements.

Several autoguider commands may be issued at the console to aid in measuring positions of items on the display and to see the output of the system to the VAX.

VAX-SHOW

The VAX-SHOW command outputs the data being sent to the VAX serial port. An example output is given below:

  1. VAX-SHOW

(x y) = 154.3 171.3 Time: est 1.71 actual 1.64

(x y) = 154.3 171.3 Time: est 1.71 actual 1.65

(x y) = 154.3 171.3 Time: est 1.71 actual 1.67

(x y) = 154.3 171.3 Time: est 1.71 actual 1.64

The Estimated time is that predicted from the current output to the next whilst the actual time reported is from the previous sample to the current one. The first output after the guide loop is started has no

previous time to act as a reference so is not shown. Any reported time-outs should be inspected carefully to ensure that the reported timeout is real.

CCDCUR

The CCDCUR command places a cursor on the image area of the display. This may be moved around with the cursor keys on the terminal (not the keypad). When Return is pressed, the current cursor position is reported in pixels and arcseconds at the current pixel scale. The cursor position is reported relative to several different origins, the two most important being the CCD image bottom left hand corner, and the centre of the current probe window (e.g. the slit probe).

Tests

Application selection

These tests check the basis default set-ups for each configuration. Several windows are mentioned. These are indicated on the display by rectangles of various colours. In order not to clutter up the display and not to mask CCD pixels, these rectangles are drawn with lines one pixel thick. They are also sometimes quite close together. Care must be taken to make sure that these are present when expected.

Head selection
note that the success of these tests is dependent on the actual cameras being connected and configured.
In the Cambridge lab configuration, all these logical heads are configured to communicate via a single
serial port thus each of these tests should pass. In the operational system, the test will pass or fail
depending on whether the appropriate camera controller is connected to the appropriate port, switched
on and responding to commands.

Acquisition tests

This section of the tests checks that the system can find stars in the field.
When the preparation section of a test asks for stars in a particular position in the field, do this by
imaging the whole field repeatedly and adjust the signal generators, oscilloscope and camera lens to
provide the appropriate display. The ICL commands APP CASS and CTA ON will start the Autoguider
displaying the whole screen. A particular cursor position of (x,y) can be marked with the ICL
command CRO x y . Make sure that the stars are bright enough to be clearly visible. Beware of stray
light leakage onto the oscilloscope screen.

Guide window tracking tests

Test 102

Description. test tracking of guide window with tracking enabled.
Preparation. Arrange for a single star to be imaged near the centre of the CCD, the position of
the star to be driven with a sine wave whose amplitude can be adjusted to cover
100 pixels peak to peak. (it may be easier to set this up with a square wave, to get
the two stars generated to be 100 pixels apart. don’t forget to switch back to the
sine wave) Use the APP CASS and CTA ON commands to update the image
display whilst adjusting.
Turn the sine wave amplitude down to 0 to get a stationary point.
Set the sine wave frequency to about 0.01 Hz
ICL> APP CASS
ICL> FLD 1
ICL> WSZ 60
ICL> TRA ON
ICL> GUI ON
ok VAX-SHOW
Expected result. The star should be found and the guide loop started with the star in the middle of
the window. The vax-show output should indicate roughly the same pixel each
time.
Preparation. Gently increase the amplitude until the star is moving about 40 pixels peak to
peak.
ICL>
Expected result. the display should plot the star movement and show a sine wave.
The sine wave should not have glitches or noise present.
The vax-show output should indicate the star position changing appropriately.
The readout window should NOT change position or size.

Preparation. Gently increase the amplitude of the sine wave to 60 pixels peak to peak.
ICL>
Expected result. The window should track across the CCD to follow the star
The vax show output SHOULD be continuous
The vax show output SHOULD NOT indicate any time-outs.
Correct data should be displayed in each readout.
The time in between readouts may be longer than normal during the tracking
operations.
The sine wave displayed on the autoguider display should be continuous without
large spikes. If there are discontinuities, record the waveform carefully.
Test 103
Preparation. Continue from Test 103, or repeat command sequence to start guide loop.
Increase the amplitude of the sine wave to 100 pixels peak to peak,
Leave this test running for 30 minutes. Only the first few cycles need be
supervised.
Expected result. After 30 minutes, the window should still be tracking faithfully.

Test 104

Description. confirm effect of disabling tracking of guide window.
Preparation. Continue from Test 104, or start guide loop with small amplitude sine wave and
increase to 100 pixels peak to peak.
Procedure. When the sine wave is in the centre of its track, issue the TRA command and
watch the results.
ICL> TRA OFF
ok VAX-SHOW
Expected result. The guide window should be frozen in the same position on the screen.
The star should leave the box at one or both sides of the window.
When the star is imaged in the window, the centroid should be reliably found.
When the star leaves the window, the system should report this via the “guiding
suspended” message and the centroids should have a negative time field.
The centroid stream to the VAX should either report valid centroid positions
matching the star or negative time fields. No vax packets should be seen with
positive time fields and co-ordinates which are not part of the regular movement
of the star.

Test 105

Description. Checks re-sizing of window with tracking on and off.
Preparation. Arrange for a single star to be imaged on the CCD, away from the edge. The star
should be stationary.
ICL> APP CASS
ICL> TRA ON
ICL> WSZ 90
ICL> FLD 1
ICL> GUI ON
Expected result. The guide loop should start, centred on the star.
Procedure. Move the star so that it is still well within the guide window but away from the
centre. The star should not be so close to the window centre to cause the window
to track. The window centre and star position should be separate and discernible.
ICL> WSZ 100
Expected result. The window should be re-sized to 100 pixels centred on the current star
position.
ICL> SEL 1
Expected result. The window should be moved back to its original position.
ICL> TRA OFF
ICL> WSZ 90
Expected result. The window should be re-sized to 90 pixels across without moving its centre.

Test 106

Description. test positioning of window at edge of CCD, that the window movement is limited
to inside the CCD.
Preparation. Setup the signal generator and oscilloscope so that the star may be moved right to
the edge of the border area (blue rectangle) in the cassegrain configuration. Start
with the star about 50 - 100 pixels inside the blue rectangle and stationary.
ICL> APP CASS
ICL> FLD 1
ICL> WSZ 100
ICL> GUI ON
ICL> TRA ON
Procedure. Move the star towards the blue border, slowly enough that the window can follow
it.
Expected result. The window should track to follow the star. Each time the window moves, the
window should be centred on the (previous) star centroid position.
Procedure. Continue moving the star stopping when the star reaches a few pixels inside the
blue rectangle. Be careful not to let the star centroid go outside the blue
rectangle.
Expected result. The window should track to follow the star, although the final position of the
window should be limited to be within the CCD, therefore its centre position will
be some way inside the CCD from the star position.

Guide window border checking tests

The system has a border defined round the edge of the CCD, or the edge of the illuminated area of the
guide fibre. When a star moves into the border area, the system should indicate this as an serious error
condition

Test 107

Description. Test CCD underscan area border limit -inside limit-.
Preparation. Setup a single star on the CCD field of view, with a sine wave moving the star
slowly to and fro. The offset and amplitude should be adjusted so that, at the peak
of its travel, the star will just remain inside the blue window shown with the APP
CASS command. It should be possible to further adjust the offset or amplitude to
make the star leave the CCD.
ICL> APP CASS
ICL> WSZ 50
ICL> TRA ON
ICL> ATG 1
ok
Expected result. The guide loop should start, following the star.
(if the star has moved out of the window in the time taken to initialise and start
the guide loop, then turn the tracking off TRA OFF until the star re-appears, then
re-enable the window tracking with TRA ON.)
The star should move to close to the blue rectangle, the cursor should follow the
star. No guide errors should be reported.

Test 108

Description. Test CCD underscan border limit - centroid outside limit -
Preparation. Run Test 107.
ok
ICL>
Procedure. Increase the amplitude (or offset) of the sine wave so that on the next cycle, the
star will cross the border line defined by the blue rectangle.
Expected result. When the guide loop measures a centroid outside the blue rectangle, the guide
loop should abort with error message
star in border !
The D task should also report an error.
%DTSK ?error string TBC?

Test 109

Description. Restarting guide loop after border error
Preparation. Run Test 108, then reduce the sine wave amplitude to zero. (you may need to
adjust the offset also) so that the star will be within the blue rectangle. (do this
blind so as not to disturb the AG in its error state).
ICL> APP CASS
ICL> FLD 1
ICL> GUI 1
Expected result. The field and guide operations should operate normally.
