[SENSe:]VOLTage[:DC]:RATio:SECondary {"OFF"|"CALCulate:DATA"|"SENSe:DATA"}
[SENSe:]VOLTage[:DC]:RATio:SECondary?
Selects the secondary measurement function for DC ratio measurements.
Parameter
Typical Return
{"OFF"|"CALCulate:DATA"|"SENSe:DATA"}, default
"OFF"
"CALC:DATA"
Configure the instrument for DC voltage ratio measurements using the 100 V range with 1 mV resolution.
Select "SENSe:DATA" as the secondary measurement. Make and retrieve measurements.

l
"CALCulate:DATA" - (Applies only to the 34465A and 34470A.) The measurement value before any
math operations are done (including NULL).
l
“SENSe:DATA” - The DC signal voltage and the DC reference voltage measurements.
l
This parameter is set to its default value after a Factory Reset (
) or Instrument Preset
(
).
[SENSe:]VOLTage[:DC]:RESolution {<

[SENSe:]VOLTage[:DC]:RESolution? [{MIN|MAX|DEF}]
Selects the measurement resolution for DC voltage and ratio measurements. Specify the resolution in the
same units as the selected measurement function, not in number of digits.

l
You can specify MIN (best resolution) or MAX (worst resolution) instead of <
resolution
>.
l
To achieve normal mode (line frequency noise) rejection, use a resolution that corresponds to an integ-
ration time that is an integral number of power line cycles.
