CH<x>:PRObe:SET
This command sets or queries the probe input resistance for the specified channel. The channel is specified by x.
Syntax CH<x>:PRObe:SET {"50ohms ON"|"50ohms OFF"}
CH<x>:PRObe:SET?
Arguments The text in quotes is not case sensitive. For returns, the case is the same as the last
command received.
"50ohms ON"
sets the input termination (when no tip is attached) to 50 Ω.
"50ohms OFF"
turns off the 50 Ω input termination.
Examples
CH6:PRObe:SET "50ohms ON"
sets the input termination of channel 6 to
50 Ω.
CH6:PRObe:SET?
might return
"50ohms OFF"
, indicating that the input
termination on channel 6 is off.
CH<x>:PRObe:STATus? (Query Only)
This command queries the probe unsigned integer error value. The channel is specified by x.
Conditions Requires a probe that supports the relevant error messages.
Syntax
CH<x>:PRObe:STATus?
Returns Returns an integer number that represents the sum total of binary error bits B0 –
B15. The error bits are not displayed; they are concatenated into the integer value.
The following is a list of the error for each bit.
• B0 – Probe disabled
• B1 – Jaws open
• B2 – Over range
• B3 – Probe temperature out of limits
• B4 – Degauss needed
• B5 – Probe tip missing
• B6 – Probe tip failed
• B7 – Probe tip not supported
• B8 – self-calibration is needed or recommended (the query will return 256 in
decimal format)
• B9 through B15 – Reserved
Examples
CH4:PROBE:STATus?
might return
2
, indicating that the probe is reporting an
open jaws error.
CH<x>:PRObe:UNIts? (Query Only)
This query-only command returns a string describing the units of measure for the probe attached to the specified channel.
The channel is specified by x.
Syntax
CH<x>:PRObe:UNIts?
Examples
CH4:PROBE:UNITS?
might return
"V"
, indicating that the unit of measure for
the probe attached to Channel 4 is Volts.
