Command Descriptions
Arguments
<NR3> is the gai
n, in volts or amps per division. For example, the voltage range is
5 V/div to 2 mV/div when using a 1X voltage probe.
Examples
CH1:SCALE 10
0E-3
sets the channel 1 gain to 100 m V/div.
CH2:SCALE? might return 1.0E0 , indicating that the current V/div setting of
channel 2 is 1 V/div.
CH<x>:VOLts
Sets or queries the vertical gain of the specified channel. The value of <x> can
vary from 1 through 4 for 4-channel instruments or 1 through 2 for 2-channel
instruments.
This command is identical to the CH<x>:SCAle command and is included for
compatibility purposes. Only CH<x>:SCAle is returned in response to a CH<x>?
query.

Syntax
CH<x>:YUNit <QString>
CH<x>:YUNit?
Arguments
<QString> is either "V" for volts or "A" for amps. This is equivalent to setting
the probe to Voltage or Current in the probe front-panel menu. This command is
case insensitive.
Examples
CH2:YUNIT might return CH2:YUNIT "V", indicating that the channel 2 units
are volts.
