Commands by Subsystem 5

Agilent InfiniiVision 5000 Series Oscilloscopes Programmer's Guide 199

:CHANnel<n>:PROBe

(see page 658)

Command Syntax

:CHANnel<n>:PROBe <attenuation>

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

<n>::={1|2|3|4}forthefour channel oscilloscope models

<n> ::= {1 | 2} for the two channel oscilloscope models

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 1000.

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> ::= 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 1000.

myScope.WriteString ":CHAN1:PROBE 10" ' Set Probe to 10:1.
