:CHANnel<n>:PROBe <atten>
:CHANnel<n>:PROBe?
Description
Sets or queries the probe ratio of the specified channel.

Remarks
 Sets the probe ratio. That is, multiply the acquired signal by a specified number (not
affect the actual amplitude of the signal).
 The set probe ratio affects the settable range of the current vertical scale.
Return
Format
The query returns 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, 200, 500, or
1000.
Example
:CHANnel1:PROBe 10 /*Sets the probe ratio of CH1 to 10X.*/
:CHANnel1:PROBe? /*The query returns 10.*/
:CHANnel<n>:PROBe:DELay
Syntax
:CHANnel<n>:PROBe:DELay <delay>
:CHANnel<n>:PROBe:DELay?
Description
Sets or queries the probe delay time of the specified channel.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<delay>
Real
-100 ns to 100 ns
0 s
Remarks
 To avoid measurement result errors arising from the transmission delay of the probe
cable, the oscilloscope provides the probe delay adjustment function for the active
probe.
 This command is only valid when an active probe is correctly connected.
Return
Format
The query returns the probe delay time in scientific notation.
