:CHANnel<n>:SCALe
Syntax
:CHANnel<n>:SCALe <scale>
:CHANnel<n>:SCALe?
Description
Sets or queries the vertical scale of the specified channel. The default unit is V.

Real
The input impedance is 1 MΩ and the
probe ratio is 1X: 1 mV to 10 V
100 mV
Remarks
You can use the :CHANnel<n>:VERNier command to enable or disable the fine
adjustment setting for the vertical scale of the specified channel. By default, the fine
adjustment is Off. At this time, you can set the vertical scale at 1-2-5 step, i.g. 10 mV, 20
mV, 50 mV…100 V. When the fine adjustment is enabled, you can further adjust the
vertical scale within a relatively smaller range to improve vertical resolution. If the
amplitude of the input waveform is a little bit greater than the full scale under the current
scale and the amplitude would be a little bit lower if the next scale is used, fine
adjustment can be used to improve the amplitude of waveform display to view signal
details.
Return
Format
The query returns the vertical scale in scientific notation.
Example
:CHANnel1:SCALe 1 /*Sets the vertical scale of CH1 to 1 V.*/
:CHANnel1:SCALe? /*The query returns 1.*/

Remarks
 Sets the probe ratio. That is, multiply the acquired signal by a specified number (not
affect the actual amplitude of the signal).
 The set probe ratio affects the settable range of the current vertical scale.
Return
Format
The query returns 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000,
2000, 5000, 10000, 20000, or 50000.
Example
:CHANnel1:PROBe 10 /*Sets the probe ratio of CH1 to 10X.*/
:CHANnel1:PROBe? /*The query returns 10.*/
