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

CALCulate:ATV:RESult:CN?<br />

This command reads <strong>the</strong> measurement values of <strong>the</strong> Carrier–to–Noise Ratio measurements.<br />

The numeric suffixes are irrelevant.<br />

This command is a query only and thus has no *RST value.<br />

Parameter<br />

RPOWer reference power<br />

NRBW noise reference bandwidth<br />

NFCorrection noise floor correction<br />

MFRelative measurement frequency (relative)<br />

CN carrier–to–noise ratio<br />

ALL Results of all measurements above, separated by commas.<br />

If a measurement result is not valid, a comma will be output only.<br />

Example<br />

CONF:ATV:MEAS CN<br />

Configures <strong>the</strong> analog TV Carrier–to–Noise Ratio measurement.<br />

INIT;*WAI<br />

Starts a new measurement and waits <strong>for</strong> <strong>the</strong> sweep end.<br />

CALC:ATV:RES:CN? NFC<br />

Reads <strong>the</strong> result of <strong>the</strong> noise floor correction measurement.<br />

or<br />

CALC:ATV:RES:CN? ALL<br />

Reads all measured values.<br />

Characteristics<br />

RST value: –<br />

SCPI: device–specific<br />

Mode<br />

CATV<br />

CALCulate:ATV:RESult:CSO?<br />

This command reads <strong>the</strong> measurement values of <strong>the</strong> Carrier–to–Second Order Beat Ratio<br />

measurements.<br />

The numeric suffixes are irrelevant.<br />

This command is a query only and thus has no *RST value.<br />

Parameter<br />

RPOWer reference power<br />

NFCorrection noise reference bandwidth<br />

MFRelative measurement frequency relative<br />

CSO carrier–to–second order beat ratio<br />

ALL Results of all measurements above, separated by commas.<br />

If a measurement result is not valid, a comma will be output only.<br />
