:EXTernal Trigger Commands 17
Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 385
:EXTernal:PROBe
(see page 1428)
Command Syntax
:EXTernal:PROBe <attenuation>
<attenuation> ::= probe attenuation ratio in NR3 format
The :EXTernal:PROBe command specifies the probe attenuation factor for the
external trigger. 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 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
:EXTernal:PROBe?
The :EXTernal:PROBe? query returns the current probe attenuation factor for the
external trigger.
Return Format
<attenuation><NL>
<attenuation> ::= probe attenuation ratio in NR3 format
