Commands Listed in Alphabetical Order
Arguments
<NR3> is a floati
ng point number that specifies the probe gain. Allowed values
depend on the specific probe.
Examples
CH2:PROBE:GAIN? might return :CH2:PROBE:GAIN 0.1000E+00 indicating
that the attached 10x probe delivers 1 V to the channel 2 BNC for every 10 V
applied to the probe input.
CH<x>:PRObe:ID? (Query Only)
Returns the type and serial number of the probe attached to channel <x>, where x
is the channel number.

Syntax
CH<x>:PRObe:ID?
Examples
CH2:PROBE:ID? might return :CH2:PROBE:ID:TYPE "10X";SERNUMBER
"N/A"
indicating that a passive 10x probe of unknown serial number is attached
to channel 2.
CH<x>:PRObe:ID:SERnumber? (Query Only)
Returns the serial number of the probe attached to channel <x>, where x is the
channel number.
NOTE. For Level 0 and 1 probes, the serial number will be "".

Syntax
CH<x>:PRObe:ID:SERnumber?
Examples
CH1:PROBE:ID:SERNUMBER? might return :CH1:PROBE:ID:SERNUMBER
"B010289"
indicating that the serial number of the probe attached to channel 1
is B010289.

CH<x>:PRObe:
ID:TYPe? (Query Only)
Returns the type of probe attached to the channel specified by <x>, where x
is the channel number. Level 2 (or higher) probes supply their exact product
nomenclatur
e; for Level 0 or 1 probes, a generic “No Probe Detected message is
returned.
NOTE. Use the command CH<x>:YUNits to query the probe type – either
“Voltage” or “ Current”.

Syntax
CH<x>:PRObe:ID:TYPe?
Examples
CH1:PROBE:ID:TYPE? might return :CH1:PROBE:ID:TYPE "P6203"
indicating that P6203-type probe is attached to channel 1.
CH<x>:PRObe:MODel
This command specifies the probe model for the specified c
hannel. If a coded
probe is attached or the specified model is not recognized, an error event is set.
The argument must be a supported probe.
To find the list of supported probes, push the front-panel channel 1, 2, 3,or4
button, then push the lower-menu More item as many times as needed to select
Deskew.PushProbe Model on the side menu and turn knob a to help you read
from the resulting list. Alternatively, you can push Te st > Analysis > Deskew >
Configure > Probe Model and read from the resulting list.

Syntax
CH<x>:PRObe:P
ROPDELay <NR3>
CH<x>:PRObe:PROPDELay?
Arguments
<NR3> is a floating point number that specifies the propagation time delay for the
connected probe.
Examples
CH1:PROBE:PROPDELAY 100E-12 sets the CH1 propagation delay to 100 ps.
CH1:PROBE:PROPDELAY? might return :CH1:PROBE:PROPDELAY 1.1E-9
indicating that the CH1 propagation delay is set to 1.1 ns.
CH<x>:PRObe:RECDESkew? (Query Only)
Returns the recommended deskew for the probe connected to the specified
channel.

CH<x>:PRObe:RECDESkew?
CH<x>:PRObe:RESistance? (Query Only)
Returns the resistance factor of the probe attached to channel <x>, where x is the
channel number.
Group
Vertical
Syntax
CH<x>:PRObe:RESistance?
Examples
CH2:PRObe:RESistance? might return :CH2:PROBE:RESISTANCE
1.0000E+6
indicating that the input resistance of the probe attached to Channel 2
is 1 MΩ.
NOTE. This query will return 0.0 if no probe is attached or the attached probe
does not report the input resistance.
