Operation 2-10
Astronics Test Systems
The following shows some examples for different commands. To set the
frequency for 200 Hz, use the following command:
"FR 200"
If there are more than one parameter to be set, just list them continuously one
after the other. For example, to set the frequency for 500.6 Hz, Level for 20.8
millivolts rms sinewave (Mode 2), and dwell time of 5 seconds, use the following
commands:
"FR 500.6 LE20.8 MD 2 T 5"
Once all the parameters for a segment is set, you can save that segment under a
segment number. For example, to save under segment 20, use the following
command:
"SA SG 20"
You can combine the two above strings into one command:
"FR 500.6 LE 20.8 MD 2 T 5 SA SG 20"
You can recall a segment and bring up the parameters on that segment by using
the following command:
"RC SG 20"
This will bring up the parameters on segment number 20.
To save all 31 segments under a file number, use the command:
"SA FI 55"
This will save all the segments under File number 55. To recall a file, use the
command:
"RC FI 60"
This will bring up all the 31 segments, which have been saved under File number
60.
There are some commands which can be used to cause the unit to output the
proper information back to the computer. The command OT (output) should be in
front of the string of commands, to receive information back from the unit. For
example, if you need to receive the status of the present segment, use the
following command:
"OT SS"
The status information will be put in a buffer. Therefore, right after the output
command, the controller (computer) has to become a receiver in order to receive
the information in the buffer. The received information would look like the
following:
"FR 02000.0 LE 10.00 MD 2"
This indicates a sinewave of 2000.0 Hz at 10.00 millivolts RMS. To receive status
on Segment 8, use the following command:
"OT SG 08"
