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 d isplay 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

double pulse delay is:

:PULS:DOUB: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.: enable double pulse mode by

[SOURce]:PULSe:DOUBle[1][:STATe] ON|OFF. Sufficient to use:

:PULS:DOUB ON

• For the commands to set the timing and level parameters, except of

period/frequency, you can explicitly specify output 1 (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

• It is recommended to test a new setting that will be programmed on

the instrument by setting it up manually.

Enable the outputs so that the instrument’s error check system is on

and possible parameter conflicts are immediately displayed.
