[SOUR]:VOLT[:LEVE][:IMM][:AMPL](?)
<DNPD>
Purpose
This command selects either DC or AC Voltage hardware, dependent upon the
DC
or
SIN|IMP|TRI|TRAP|SYMS
parameter
included in the most-recent
FUNC
command.
<DNPD>
The 'decimal numeric program data' is a number which sets the required output voltage, expressed in units of DC or RMS AC Volts.
It will automatically choose the 'best' hardware range for the defined voltage output. The 9100 will accept signed or unsigned
positive values for DC Voltage.
For details of local operation and parameter limitations, refer to Volume 1, Section 4, Sub-Sections 4.3 (DCV), 4.4 (ACV) or 4.17
(Logic Levels).
Response to Query Version
The instrument will return the present DC or AC voltage output value, dependent upon the
DC
or
SIN|IMP|TRI|TRAP|SYMS
parameter implicit, or included, in the most-recent
FUNC
command. The returned number will be in standard scientific format
(for example: -200
µ
V DC would be returned as
-2.0E-4
— positive numbers, however, are unsigned)
6.6.4.4
[SOUR]:VOLT[:LEVE][:IMM]:HIGH(?) <DNPD>
Purpose
This command sets the high (most positive) 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.
<DNPD>
The 'decimal numeric program data' is a number which sets the required high-level (most-positive) 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:LOW
command for the same waveshape.
The value of
<DNPD>
cannot be equal to or more negative than that sent as the
<DNPD>
with the corresponding
VOLT:LOW
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 high 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).
