:CHANnel<n>:PROBe
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 from 0.001 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.
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
