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.

Commands Listed in Alphabetical Order
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.

Syntax
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.

CH<x>:PRObe:
SIGnal
This command specifies the input bypass setting of a TekVPI probe attached to
channel <x>, where x is the channel number. The probe must support input bypass,
for example T
CP0001. This command is ignored if sent to an unsupported probe.
Group

Syntax
CH<x>:PRObe:SIGnal {BYPass|PASS}
CH<x>:PRObe:SIGnal?
Arguments
BYPass sets the probe to Bypass mode.
PASS sets the probe to Pass mode.
CH<x>:PRObe:UNIts? (Query Only)
Returns a string describing the units of measure for the probe attached to channel
<x>, where x is the channel number.
NOTE. Use the command CH<x>:YUNits to set the probe type to “Voltage”
or “Current”.
Group
Vertical
Syntax
CH<x>:PRObe:UNIts?
Examples
CH4:PROBE:UNITS? might return :CH4:P ROBE:UNITS "V" indicating that the
units of measure for the probe attached to channel 4 are volts.
CH<x>:SCAle
This command specifies the vertical scaleforthechannelspecifiedby<x>,where
x is the channel number. This setting controls the vertical size of the acquisition
window as well as the display scale. The range and resolution of scale values
depends on the probe attached and any other external factors you have specified.
For a signal with constant amplitude, increasing the scale causes the waveform to
be displayed smaller. Decreasing the scale causes the waveform to be displayed
larger.
