Volt / DIV
PRx:VOLT_DIV,PRx:VDIV
Command/Query
Description When used with the
"PRx"
argument for channel number, the VOLT/DIV
command sets the vertical sensitivity at the probe tip. The effective gain of
the differential amplifier, including any attenuating passive probes, is
factored into the vertical sensitivity. The command will also set the
Atten/Gain control mode to Auto if it was set to Manual mode.
The valid range of arguments is effected by the presence of an attenuating
probe on the input. If an out-of-range value is entered, the oscilloscope will
set the vertical sensitivity to the closest valid value and set the VAB bit (bit
2) in the STB register.
The
PRx:VOLT_DIV?
query returns the vertical sensitivity at the probe
input of the specified channel.
