10 :CHANnel<n> Commands
:CHANnel<n>:PROBe
(see page 798)
Command Syntax
:CHANnel<n>:PROBe
<attenuation>
<attenuation> ::= probe attenuation ratio in NR3 format
<n> ::= 1 to (# analog channels) in NR1 format
The obsolete attenuation values X1, X10, X20, X100 are also supported.
The :CHANnel<n>:PROBe command specifies the probe attenuation factor for the
selected channel. The probe attenuation factor may be 0.1 to 10000. This
command does not change the actual input sensitivity of the oscilloscope. It
changes the reference constants for scaling the display factors, for making
automatic measurements, and for setting trigger levels.
Query Syntax
:CHANnel<n>:PROBe?
The :CHANnel<n>:PROBe? query returns the current probe attenuation factor for
the selected channel.
Return Format
<attenuation><NL>
<attenuation> ::= probe attenuation ratio in NR3 format

Example Code
' CHANNEL_PROBE - Sets the probe attenuation factor for the selected
' channel. The probe attenuation factor may be set from 0.1 to 10000
.
myScope.WriteString ":CHANnel1:PROBe 10" ' Set Probe to 10:1.
