LDX-3232 Current Source Command Set

C H A P T E R 3

The syntax of the LDX-3232 High Compliance Current Source commands follows the rules laid out in the GPIB-IEEE488 standard. Colons (:) indicate the start of a new command path, while semicolons (;) indicate a separation of commands within a command string. A leading colon on a command may be used to return the LDX-3232 High Compliance Current Source command parser to the command path root (see Figure 3.1).

Spaces or white space may be used to separate commands and/or data (after the command header or query question mark). Spaces or white space must be used to separate the command (header) from the first parameter (or program data). The following examples show valid syntax for commands with the LDX-3232 High Compliance Current Source:

•LAS:display:ldi

•Laser:limit:ldi 400

•LAS:DIS 1; las:set:ldi?

•Las:MODE:Mdp; LAS:OUT 1

The following are examples of invalid syntax for the LDX-3232 High Compliance Current Source. These command strings would produce an erroneous result, as explained:

LAS:MODE MDP	Missing colon, MODE? expected
LAS:MODE:ILBW DEC	Missing semicolon, DEC command generates an error
LAS:DIS ?	Space not allowed before question mark, DIS command
	expected
Las:LDI33;dis?	Space missing between LDI command and the parameter
	value, 33

For further clarity in programming, the (Boolean) values of one (1) and zero (0) may be used or their names as indicated in the following table:
