Channel<N>:Probe - Agilent Technologies InfiniiVision 7000A Series Programmer's Manual

:CHANnel<n>:PROBe
Command Syntax
:CHANnel<n>:PROBe <attenuation>
<attenuation> ::= probe attenuation ratio in NR3 format
<n> ::= {1 | 2 | 3 | 4} for the four channel oscilloscope models
<n> ::= {1 | 2} for the two channel oscilloscope models
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
