RECOMMENDED in
dicates the measurement accuracy might be improved by
degaussing the probe.
PASSED indica
tes the probe is degaussed.
FAILED indicates the degauss operation failed.
RUNNING indicates the probe degauss operation is currently in progress.
CH<x>:PRObe:FORCEDRange
This comma
nd specifies the range of a TekVPI probe attached to the channel
specified by <x>, where x is the channel number.
NOTE. This command will return
PASSED
for probes that do not support degauss
operations.

CH<x>:PRObe:FORCEDRange <NR3>
CH<x>:PRObe:FORCEDRange?
Arguments
<NR3> is a floating point number that specifies the range, which is probe specific.
Returns
The query form of this command returns 0.0 for probes that do not support
forced ranges.
CH<x>:PRObe:GAIN
This command specifies the gain factor for the probe attached to the channel
specified by <x>, where x is the channel number. The "gain" of a probe is the
output divided by the input transfer ratio. For example, a common 10x probe
has a gain of 1V.

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.
Group

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 "".

Vertical
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.
