SCPI Parameter Types

The following parameter types are used:

Accepts all commonly used decimal representation of

numbers including optional signs, decimal points, and

scientific notation:

For Example: 123, 123e2, -123, -1.23e2, .123, 1.23e-

2, 1.2300E-01

Represents a single binary condition that is either true or

false. True is represented by a 1 or ON; false is

represented by a 0 or OFF. Queries return 1 or 0.

Selects from a finite number of predefined strings.

Error Codes

The unit responds to all commands with either:

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 pulse width, 2.3 ms delay, 10 Hz internal trigger, and 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 pulse width 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
