CALibrate:RE
Sults:SPC:SCOPE? (Query Only)
This query returns the status of the last SPC run for the oscilloscope portion of
the instrument (doesn't include the RF portion). This query is synonymous to
CALibrate:I
NTERNal:STATus:SCOPE?
Group
Calibration and Diagnostic
Syntax
CALibrate:RESults:SPC:SCOPE?
Returns
This query will return one of the following:
INIT indicates the oscilloscope portion of the instrument has not been calibrated.
PASS indicates the oscilloscope internal calibration completed successfully.
FAIL indicates the oscilloscope internal calibra
tion did not complete successfully.
RUNNING indicates the oscilloscope internal calibration is currently running.
Examples
CAL:RESULTS:SPC:SCOPE? might return INIT indicating that th
e oscilloscope
portion of the instrument has not been calibrated.
CALibrate:RF (No Query Form)
This command begins the RF calibration process. You should first disconnect
all cables and probes from the RF input before using this command. The
calibration process takes approximately 3 minutes. This command is identical to
CALibrate:RF:STARt.
NOTE. If you run the signal path calibration (SPC) commands, you don’t need
to run this command as well.
NOTE. Disconnect or otherwise remove all input signals prior to starting
self-calibration. The self-calibration can take several minutes to complete.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

Syntax
CH<x>?
CH<x>:AMPSVIAVOLTs:ENAble
This command specifies the state of the amps via volts feature for the specified
channel. This feature supports measuring current via the voltage drop across a
resistor (1–4).
Group
Vertical
Syntax
CH<x>:AMPSVIAVOLTs:ENAble {<NR1>|OFF|ON}
CH<x>:AMPSVIAVOLTs:ENAble?
Arguments
OFF sets the amps via volts function for channel <x> to off.
ON sets the amps via volts function for channel <x> to on.
<NR1> = 0 sets the amps via volts function to off. Any other value sets the
functiontoon.
Examples
CH1:AMSVIAVOLTS:ENABLE ON turns on the amps via volts feature for
channel 1.
CH<x>:AMPSVIAVOLTs:FACtor
This command specifies the amps via volts factor for the specified channel (1–4).
Group
Vertical
Syntax
CH<x>:AMPSVIAVOLTs:FACtor <NR3>
CH<x>:AMPSVIAVOLTs:FACtor?
Arguments
<NR3> is a double-precision ASCII string that represents the amps via volts factor.
Examples
CH1:AMPSVIAVOLTS:FACTOR 15.5 sets the amps via volts factor for channel 1
to 15.5.
