The System Commands group lets you use common commands and
test the LW120 for proper operation. The Time Out field sets system
timeout in units of seconds. The time out is required by the GPIB ink in
case your instrument does not communicate properly with on the bus.
To avoid bus lockout, set the time out to small values. The default time
out setting is 2. The *RST, *CLS buttons are used for clearing error
queue, or resetting the instrument to factory defaults.
The *TST? Invokes the LW120 selftest routine. You should use this
test when you suspect that something is wrong with your instrument.
The LW120 executes this test and generates a response that is
placed in the field below the *TST? button. The response to the
selftest command is numeral. Any response, besides "0", means that
your instrument failed the selftest. Additional information on the *TST?
command is available in chapter 4 of this manual.
The *TST? Invokes hardware selftest routine. This test
destructive to the last setting of the LW120. Use this te
routine only when absolutely necessary to ascertain
functional failure of the LW120.
The *IDN? queries the generator's identity. The response is placed in
the field next to the *IDN? button. The response is organized into four
fields, separated by commas, as shown below:
Low-level SCPI commands and queries can be directly sent to the
LW120 from the Command field and the LW120 will response to
queries in the Response field. The command editor is very useful
while developing your own application. Build your confidence or test
various commands using the command editor. This way you can
assure that commands or syntax that you use in your application will
respond exactly the same way as it responds to the editor commands.
A complete list of SCPI commands is available in Chapter 4 of this
manual.
