CALCulate Subsystem (CATV, K20) R&S <strong>ZVL</strong>‑<strong>K1</strong><br />

CALCulate:DTV:LIMit:EVMPeak:UPPer<br />

This command defines <strong>the</strong> upper limit of <strong>the</strong> error vector magnitude peak in % <strong>for</strong> <strong>the</strong> Overview /<br />

Modulation Errors measurement. If <strong>the</strong> wrong unit is set, <strong>the</strong> command produces an execution<br />

error. The unit is set via <strong>the</strong> CALCulate:DTV:UNIT:POWer:EVMPeak command.<br />

Parameter<br />

0.01 to 100%<br />

Example<br />

CALC:DTV:UNIT:POW:EVMP PCT<br />

Sets <strong>the</strong> unit <strong>for</strong> <strong>the</strong> error vector magnitude peak to %.<br />

CALC:DTV:LIM:EVMP:UPP 1<br />

Sets <strong>the</strong> upper limit <strong>for</strong> <strong>the</strong> error vector magnitude peak to 1%.<br />

Characteristics<br />

RST value: 22%<br />

SCPI: device–specific<br />

Mode<br />

CATV<br />

CALCulate:DTV:LIMit:EVMRms:LOWer<br />

This command defines <strong>the</strong> lower limit of <strong>the</strong> root mean square value of <strong>the</strong> error vector<br />

magnitude in dB <strong>for</strong> <strong>the</strong> Overview / Modulation Errors measurement. If <strong>the</strong> wrong unit is set, <strong>the</strong><br />

command produces an execution error. The unit is set via <strong>the</strong><br />

CALCulate:DTV:UNIT:POWer:EVMRms command.<br />

Parameter<br />

0 to 80 dB<br />

Example<br />

CALC:DTV:UNIT:POW:EVMR dB<br />

Sets <strong>the</strong> unit <strong>for</strong> <strong>the</strong> root mean square value of <strong>the</strong> error vector magnitude to dB.<br />

CALC:DTV:LIM:EVMR:LOW 5<br />

Sets <strong>the</strong> lower limit <strong>for</strong> <strong>the</strong> root mean square value of <strong>the</strong> error vector magnitude to 5 dB.<br />

Characteristics<br />

RST value: 27.1 dB<br />

SCPI: device–specific<br />

Mode<br />

magnitude in % <strong>for</strong> <strong>the</strong> Overview / Modulation Errors measurement. If <strong>the</strong> wrong unit is set, <strong>the</strong><br />

command produces an execution error. The unit is set via <strong>the</strong><br />

CALCulate:DTV:UNIT:POWer:EVMRms command.<br />
