:CHANnel<n> Commands 10

Agilent InfiniiVision 2000 X-Series Oscilloscopes Programmer's Guide 227

:CHANnel<n>:PROBe

(see page 790)

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 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, for making automatic measurements, and for setting trigger levels.

Query Syntax

:CHANnel<n>:PROBe?

The :CHANnel<n>:PROBe? query returns the current probe attenuation

factor for the selected channel.

Return Format

<attenuation> ::= probe attenuation ratio in NR3 format

Example Code

' CHANNEL_PROBE - Sets the probe attenuation factor for the selected

' channel. The probe attenuation factor may be set from 0.1 to 10000

myScope.WriteString ":CHANnel1:PROBe 10" ' Set Probe to 10:1.
