Related Commands
CH<x>:OFFSet, CH<x>:POSition
Arguments
NR3 is the ve
rtical channel scale in units per division.
Examples
CH4:SCALE 5.0E-01 sets the scale for Chan nel 4 to 500 mV per division.
CH2:SCALE? might return CH2:SCALE 0.02000000000, indicating that the
current scale setting of Channel 2 is 20 mV per division.
CH<x>:UNIts
This command sets or queries the units for the specified channel. The channel is
specified by x, which can be 1 through 8. Sending this command is the equivalent
to setting the Units control in the Channel section of the Vertical Setup dialog
box. You can use this control to ove rride the automatic selection of units for the
selected channel. If you set this value to AUto, the instrument automatically
selects the units. If you set this value to Volt, Watt, or Amp, the instrument will
apply these units to the vertical axis.
The selections in this control are Auto, Volt, Amp, and Watt. When you
change the units setting, all vertical units are reported as specified and no data
transformations take place.
For TDR waveforms, the Units control in the Vertical Setup dialog box is not
active. Use the TDR:CH<x>:UNIts command to set and query units in TDR.
The units available are Rho, Ohm, and Volt. When you change units of TDR
waveforms, data transformations take place. The default is Rho.

Syntax
CH<x>:UNIts { AUto | Volt | Watt | A mp }
CH<x>:UNIts?
Arguments
AUTO sets the units for the specified channel so that they are automatically
determined by the instrument (depends on the probe attached to the specified
channel).
Volt sets the vertical-axis units for the specified channel to volts.
Watt sets the vertical-axis units for the specified channel to watts.
Amp sets the vertical-axis units for the specified channel to amperes.
