14 :EXTernal Trigger Commands

:EXTernal:PROBe

(see page 798)

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 10000. 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> ::= probe attenuation ratio in NR3 format
