Thank you, everyone, for the response to my high voltage / steps question.
Very understandable now.
Gerry, to jump from one HV to another in ISL:
_Set(HV_DAC,new_high_voltage);
where 'HV_DAC' is the instrument name for the high voltage DAC in steps
and 'new_high_voltage' is the one you want to go to, again, in steps.
