Commands Description

BUS:UPPerthreshold{:MATH|:

MATH1}

This command speciﬁes the upper threshold for the math waveform.

BUS:UPPerthreshold:REF<x> This command sets the upper threshold for each reference waveform.

Calibration and Diagnostic Command Group

The Calibration and Diagnostic commands provide information about the

current state of oscilloscope calibration. They also initiate internal signal path

calibration (SPC) or execute diagnostic tests. Commands that are speciﬁc to

factory calibration are not described in this manual. Instead, they are described

in the Service Manual Documentation CD-ROM in PDF format. You can also

order a printed copy.

Command

Description

CALibrate:RESults:FACtory:SCOPE? This query returns the factory calibration status for the oscilloscope (doesn't include RF or

AFG) of the instrument.

CALibrate:RESults:SPC? Returns the results of the last SPC operation.

CALibrate:RESults:SPC:RF? This query returns the status of the last SPC run for the RF portion of the

instrument (doesn't include analog channels) . This query is synonymous with

CALibrate:INTERNal:STATus:RF?

Available on mixed domain oscilloscope models with RF enabled.

CALibrate:RESults:SPC:SCOPE? 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:INTERNal:STATus:SCOPE?

CALibrate:RF

This command begins the RF calibration process.

Available on mixed domain oscilloscope models with RF enabled.

CALibrate:RF:STARt

This command is identical to

CALIBRATE:RF.

Available on mixed domain oscilloscope models with RF enabled.

CALibrate:RF:STATus? This query returns the status of the last RF calibration.

Available on mixed domain oscilloscope models with RF enabled.

DIAg:LOOP:OPTion Sets the self-test loop option.

DIAg:LOOP:OPTion:NTIMes Sets the self-test loop option to r un N times.

DIAg:LOOP:STOP Stops the self-test at the end of the current loop.

DIAg:RESUlt:FLAg? Returns the pass/fail status from the last self-test sequence execution.

DIAg:RESUlt:LOG? Returns the internal results log from the last self-test sequence execution.

DIAg:SELect Runs self tests on the speciﬁed system subsystem.

DIAg:SELect:<function> Speciﬁes which of the subsystems will be tested when the DIAg:STATE EXECute

command is run.

DIAg:STATE S ets the oscilloscope operating state.

Conﬁguration Command Group

Use the queries in the Conﬁguration Command Group to determine whether a

particular feature is present.

Table 2-20: Conﬁguration Commands

Command

Description

CONFIGuration:ADVMATH?

This query returns a boolean value to indicate whether the

instrument supports the advanced math feature.

CONFIGuration:AFG? Indicates whether or not the arbitrary function generator

hardware is present, and the arbitrary function generation feature

is enabled.

CONFIGuration:ANALOg:BANDWidth? This query returns the maximum bandwidth for analog channels.

Command

Description

CONFIGuration:ANALOg:GNDCPLG?

This query returns a boolean value to indicate whether the

instrument supports the ground coupling feature for analog

channels. As this feature is not supported on M SO /DPO4000B

or MDO4000/B/C models, this query always returns 0.

CONFIGuration:ANALOg:MAXBANDWidth? Returns the maximum bandwidth for analog channels.

CONFIGuration:ANALOg:MAXSAMPLERate? This query returns the m aximum sample rate for analog channels.

CONFIGuration:ANALOg:NUMCHANnels? This query returns the number of analog channels.
