INZ<br />

Input Impedance<br />

Specifies the value of input impedance expected at the active input port.<br />

Syntax<br />

Equivalent Softkey: fIJKIl’ Z 508 75Q .<br />

Preset Value: Returns impedance to the power-on value.<br />

Related Comm<strong>and</strong>s: AUNITS.<br />

Example<br />

OUTPUT 718;"INZ 75;" Changes input impedance to 75 ohms.<br />

OUTPUT 718 ; "AUNITS V; ” Changes amplitude units to volts.<br />

Description<br />

INZ Input Impedance<br />

The actual impedance can be affected only by internal hardware. With the exception of Option<br />

001 or 011 (<strong>HP</strong> 859OL or <strong>HP</strong> 85913 only), the spectrum analyzer hardware supports 5Ofl only.<br />

The INZ comm<strong>and</strong> is used for computation purposes during power or voltage conversions.<br />

The INZ comm<strong>and</strong> affects only the amplitude results that are reported in absolute relative<br />

power (dBm units or watts). (See “AUNITS.“)<br />
