Commands by Subsystem 3
Agilent InfiniiVision 5000 Series Oscilloscopes Programmer's Reference 175
:EXTernal:PROBe
(see page 530)
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
