numbers including optional signs, decimal points and
scientific notation: 123, 123e2, -123, -1.23e2, .123,
1.23e-2, 1.2300E-01.
<boolean value>
Represents a single binary condition that is either true
or false. True is represented by a 1 or ON; false is rep-
resented by a 0 or OFF. Queries return 1 or 0.
<identifier>

ok <cr><lf> or ?n <cr><lf>
Where "n" is one of the following error codes:
1 Incorrect prefix, i.e. no colon or * to start command.
2 Missing command keyword.
3 Invalid command keyword.
4 Missing parameter.
5 Invalid parameter.
6 Query only, command needs a question mark.
7 Invalid query, command does not have a query form.
8 Command unavailable in current system state.
Programming Examples
Example 1) 20 ms pulsewidth, 2.3 ms delay, 10 Hz, internal trigger, continuous
operation.
:PULSE1:STATE ON <cr> <lf>
enables channel A
:PULSE1:POL NORM <cr> <lf>
sets polarity to active high
:PULSE:WIDT 0.020 <cr> <lf>
sets pulsewidth to 20 ms
:PULSE1:DELAY 0.0023 <cr> <lf>
sets delay to 2.3 ms
:PULSE0:MODE NORM <cr> <lf>
sets system mode to continuous
:PULSE0:PER 0.1 <cr> <lf>
sets period to 100 ms (10 Hz)
:PULSE0:EXT:MODE DIS <cr> <lf>
disables the external trigger
To start the pulses use either of the following commands:
:PULSE0:STATE ON <cr> <lf>
starts the pulses
:INST:STATE ON <cr> <lf>
alternate form to start pulses.
