Programming Recommendations

Here are some recommendations for programming the instrument:

Start programming from the default setting. The common command for setting the default setting is:

*RST

Switch off the automatic update of the display to increase the programming speed. The device command for switching off the display is:

:DISPlay OFF

The SCPI standard defines a long and a short form of the commands. For fast programming speed it is recommended to use the short forms. The short forms of the commands are represented by upper case letters. For example the short form of the command to set 100 ns delay is:

:PULS:DEL 100NS

To improve programming speed it is also allowed to skip optional subsystem command parts. Optional subsystem command parts are depicted in square brackets, e.g.: set amplitude voltage of output 1:

[SOURce]:VOLTage[1][:LEVel][:IMMediate][:AMPLitude]. Sufficient to use: :VOLT 1.2V

For the commands to set the timing and level parameters, except of period/frequency, you can explicitly specify the output to be programmed (for compatibility reasons). If there is no output specified, the commands will set the default output 1.

So, for setting a high level of 3 Volts for output 1 the commands are:

:VOLT:HIGH 3V # sets high level of 3 V at out 1

:VOLT1:HIGH 3V # sets high level of 3 V at out 1
