:CHANnel<n> Commands 10
Agilent InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide 231
:CHANnel<n>:PROBe
(see page 860)
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 1000.
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.
If an AutoProbe probe is connected to the oscilloscope, the attenuation
value cannot be changed from the sensed value. Attempting to set the
oscilloscope to an attenuation value other than the sensed value produces
an error.
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 1000.
myScope.WriteString ":CHANnel1:PROBe 10" ' Set Probe to 10:1.
