[SENSe:]{FREQuency|PERiod}:VOLTage:RANGe:AUTO {OFF | ON} [, (@<ch_list>)]
[SENSe:]{FREQuency|PERiod}:VOLTage:RANGe:AUTO? [(@<ch_list>)]
Enables or disables voltage autoranging for frequency and period measurements. Autoranging is convenient
because the instrument automatically selects the range for each measurement based on the input signal detected.
Parameter is shared between frequency and period measurements. Setting or querying the parameter with
the FREQuency version of this command is identical to setting or querying it with the PERiod version.
Parameter Typical return
{OFF | ON}. Default: ON 0 (OFF) or 1 (ON)
Configure frequency measurements, and turn autorange on.
CONF:FREQ
FREQ:VOLT:RANG:AUTOON
– Autorange thresholds:
Down range at: <10% of range
Up range at:>120% of range.
–
The input signal for frequency or period measurements has an AC voltage component. Use this command to
select a fixed voltage range for frequency and period measurements. Use [SENSe:] {FREQuency|PERi-
od}:VOLTage:RANGe:AUTO to disable or enable voltage autoranging or use CONFigure:{ FREQuency|PERiod} to
select voltage autoranging by default.
– Selecting a fixed range (see [SENSe:]CURRent:{AC|DC}:RANGe command) disables autoranging.
– This parameter is set to its default value after a Factory Reset (*RST command).
