CALCulate:DTV:RESult Subsystem (CATV, K20)
The CALCulate:DTV:RESult subsystem displays the measurement results for digital TV measurements.
Commands of the CALCulate:DTV:RESult Subsystem
– CALCulate<1|2>:DTV:RESult?
CALCulate<1|2>:DTV:RESult?
This command reads the measurement values for the digital TV measurements.
The numeric suffixes <1|2> are irrelevant.
This command is a query only and thus has no *RST value.
Parameter
Spectrum SALower lower shoulder attenuation
SAUPper upper shoulder attenuation
Overview MERRms root mean square of the modulation error rate
MERPeak peak of the modulation error rate
EVMRms root mean square of the error vector magnitude
EVMPeak peak of the error vector magnitude
CFOFfset carrier frequency offset
SROFfset symbol rate offset
ALL Results of all measurements above, separated
by commas.
If a measurement result is not valid, a comma
will be output only.
Modulation
Errors
IMBalance amplitude imbalance
QERRor quadrature error
CSUPpression carrier suppression
PJITter phase jitter
ALL Results of all measurements above, separated
by commas.
If a measurement result is not valid, a comma
will be output only.
Example
CONF:DTV:MEAS MERR

INIT;*WAI
Starts a new measurement and waits for the sweep end.
CALC:DTV:RES? QERR
Reads the result (quadrature error) of the Modulation Errors measurement.
or
CALC:DTV:RES? ALL
Reads all measured values.
