[SOUR]:VOLT[:LEVE][:IMM]:LOW(?)
<DNPD>
Purpose
This command sets the low (most negative) voltage level for the square or pulsed voltage output , which has been selected by the
SQU
or
PULS
parameter included in the most-recent
FUNC
command. Separate values are recorded for
SQU
and
PULS
functions.
<DNPD>
The 'decimal numeric program data' is a number which sets the required low-level (most-negative) output voltage of the
programmed waveshape, expressed in units of Volts. It will automatically choose the 'best' hardware range for the defined voltage
output, in conjunction with the corresponding
VOLT:HIGH
command for the same waveshape.
The value of
<DNPD>
cannot be equal to or more positive than that sent as the
<DNPD>
with the corresponding
VOLT:HIGH
command for the same waveshape. The 9100 will accept signed or unsigned positive values.
For details of local operation and parameter limitations, refer to Volume 1, Section 4, Sub-Sections 4.9 (Frequency), 4.10 (Mark/
Period), 4.11 (% Duty Cycle) or 4.16 (Logic Pulses).
Response to Query Version
The instrument will return the present low level voltage output value, associated with the
SQU
or
PULS
parameter implicit, or
included, in the query command. The returned number will be in standard scientific format (for example: +200mV would be
returned as
2.0E-1
— positive numbers are unsigned)
