Appendix D: Convert Model 2400 to Model 2461 code

Sweeps

In the Model 2461, sweep commands include all the settings for the sweep in the sweep commands.
An example of a sweep set up for the Model 2400 compared to a sweep set up for a Model 2461 is
shown in the table below. These examples configure the instrument to output a voltage sweep from
0 V to 0.55 V in 56 steps with a 100 ms delay.

In the Model 2461, when you create a sweep, a trigger model for that sweep is automatically created.
You can view and create sweeps and the related trigger models using the front panel.
The list sweep for the Model 2400 compared to the Model 2461 is similar. An example of a list sweep
for the Model 2400 compared with one done for the Model 2461 is shown in the following table. Note
that for the Model 2461, the trigger count and voltage source mode do not have to be specified in
separate commands, and the output is turned on and off automatically as part of the sweep.
