DISPlay Subsystem (Noise Figure, K30) R&S <strong>ZVL</strong>‑<strong>K1</strong><br />

DISPlay[:WINDow]:TRACe:Y[:SCALe]:RLEVel:AUTO<br />

This command enables or disables <strong>the</strong> automatic reference level detection.<br />

The numeric suffixes are irrelevant <strong>for</strong> this command.<br />

Parameter<br />

ON | OFF<br />

Example<br />

DISP:TRAC:Y:RLEV:AUTO ON<br />

Turns on automatic reference level detection.<br />

Characteristics<br />

*RST value: ON<br />

SCPI: con<strong>for</strong>m<br />

Mode<br />

NF<br />

DISPlay[:WINDow]:TRACe:Y[:SCALe]:TOP<br />

This command sets <strong>the</strong> maximum (top) Y–axis display value <strong>for</strong> <strong>the</strong> specified trace display. It<br />

has no affect if automatic scaling of <strong>the</strong> Y–axis is enabled or <strong>the</strong> specified trace is not currently<br />

active.<br />

The numeric suffixes indicate <strong>the</strong> measurement results: Trace 1 is always used <strong>for</strong> noise<br />

results, and trace 2 is always used <strong>for</strong> gain results.<br />

Parameter<br />

noise figure: –75 dB to 75 dB<br />

noise temperature: –999990000 K to 999990000 K<br />

gain: –75 dB to 75 dB<br />

Example 1<br />

DISP:DATA:TRAC1 NFIG<br />

Sets <strong>the</strong> noise figure to trace1.<br />

DISP:TRAC:Y:TOP 30<br />

Sets <strong>the</strong> maximum Y–axis display to 30 dB <strong>for</strong> trace 1.<br />

Example 2<br />

DISP:DATA:TRAC1 TEFF<br />

Sets <strong>the</strong> noise temperature to trace1.<br />

DISP:TRAC:Y:TOP 100<br />

Sets <strong>the</strong> maximum Y–axis display to 100 K <strong>for</strong> trace 1.<br />

Example 3<br />

DISP:TRAC2:Y:TOP 10<br />

Sets <strong>the</strong> maximum Y–axis display to 10 dB <strong>for</strong> trace 2.<br />

Characteristics<br />

*RST value: 20 dB <strong>for</strong> noise and gain figure, 10000K <strong>for</strong> noise temperature<br />
