Commands Listed in Alphabetical Order
Syntax
CH<x>:PRObe:C
OMMAND <Q String>, <QString>
Arguments
<QString> are quoted strings specifying the probe command and value to set in
the probe attached to the specified channel.
Examples
CH1:PROBE:COMMAND “MODE”, “4–4V1MH z” sets a Tektronix VPI-DPG probe
to the 4-4V1MHz mode.
CH1:PROBE:COMMAND “OUTPUT”, “ON” turns the output of a Tektronix
VPI-DPG probe on.
CH1:PROBE:COMMAND?“MODE” might return CH1:PROBE:COMMAND
“MODE”,“4-4V1MHZ”
.
CH<x>:PRObe:DEGAUss (No Query Form)
This command starts a degauss auto-zero cycle on a TekVPI current probe
attached to the input channel specified by <x>, where x is the channel number.

Syntax
CH<x>:PRObe:DEGAUss EXECute
Arguments
EXECute initiates the degauss operation.
CH<x>:PRObe:DEGAUss:STATE? (Query Only)
This command returns the state of the probe degauss for the channel specifiedby
<x>, where is x is the channel number.
NOTE. This command will return
PASSED
for probes that do not support degauss
operations.

Syntax
CH<x>:PRObe:DEGAUss:STATE?
Returns
NEEDED indicates the prob
e should be degaussed before taking measurements.

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.

Syntax
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.

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

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 "".
