Remarks
SEND: indicates a single-ended probe head.
DIFFerential: indicates a differential probe head.
Return Format
The query returns SEND or DIFF.
:CHANnel<n>:PROBe
Syntax
:CHANnel<n>:PROBe <atten>
:CHANnel<n>:PROBe?
Description
Sets or queries the probe ratio of the probe currently connected to the specified analog channel.

Remarks
Probe ratio = displayed amplitude of the signal under test/actual amplitude of the signal under test
The oscilloscope will display the waveforms of the signal under test based on the currently set probe
ratio, without affecting the actual amplitude of the signal.
If you select a different probe ratio, the range for the vertical scale (refer to the :CHANnel<n>:SCALe
command) of the analog channel is different.
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, or 1000.
:CHANnel<n>:SCALe
Syntax
:CHANnel<n>:SCALe <scale>
:CHANnel<n>:SCALe?
Description
Sets or queries the vertical scale of the specified analog channel. The unit is related to the current
amplitude unit of the specified analog channel. The default unit is V/div.

Real
Related to the current input impedance and the probe ratio
(the default unit is V/div).
When the input impedance is 50 Ω and the probe ratio is 1X,
the value of <scale> is from 1 mV/div to 1 V/div.
When the input impedance is 1 MΩ
and the probe ratio is 1X,
the value of <scale> is from 1 mV/div to 5 V/div.
1 V/div
Return Format
The query returns the vertical scale in scientific notation.
