In a step whose ramp is set to on, the voltage changes linearly from the voltage setting of the previous step to the specified voltage.

Because we want to change the voltage from 0 V to 10 V, the step before the step that will be set to 10 V must be set to 0 V. For this purpose, we will set short starting voltage steps before steps that will be set to 10 V. In this example, steps 2, 4, and 6 are the starting voltage steps. The minimum time resolution for the step execution time is 100 µs. Do not set the step execution time to 0 s.

If you create a sequence without starting voltage steps, the waveform shown below will be output. Note that even if the ramp is turned on in steps 2, because the previous step is set to 10 V, a ramp waveform will not be produced.

For the procedure to set steps on the PCR-LE Series, see “Sequence creation basics”.

Likewise, frequency sweeps also need starting frequency steps.
