INPut Subsystem R&S <strong>ZVL</strong>‑<strong>K1</strong><br />

INPut Subsystem<br />

The INPut subsystem controls <strong>the</strong> input characteristics of <strong>the</strong> RF inputs of <strong>the</strong> instrument.<br />

Commands of <strong>the</strong> INPut Subsystem<br />

– INPut:ATTenuation<br />

– INPut:ATTenuation:AUTO<br />

– INPut:GAIN:STATe (option RF Preamplifier, B22)<br />

– INPut:IMPedance<br />

– INPut:UPORt[:VALue]?<br />

– INPut:UPORt:STATe<br />

INPut:ATTenuation<br />

This command programs <strong>the</strong> input attenuator. To protect <strong>the</strong> input mixer against damage from<br />

overloads, <strong>the</strong> setting 0 dB can be obtained by entering numerals, not by using <strong>the</strong> DEC<br />

command.<br />

The attenuation can be set in 5 dB steps. If <strong>the</strong> defined reference level cannot be set <strong>for</strong> <strong>the</strong> set<br />

RF attenuation, <strong>the</strong> reference level will be adjusted accordingly.<br />

In <strong>the</strong> default state with Spectrum Analyzer mode, <strong>the</strong> attenuation set on <strong>the</strong> step attenuator is<br />

coupled to <strong>the</strong> reference level of <strong>the</strong> instrument. If <strong>the</strong> attenuation is programmed directly, <strong>the</strong><br />

coupling to <strong>the</strong> reference level is switched off.<br />

Parameter<br />

in dB; range specified in data sheet<br />

Example<br />

INP:ATT 30dB<br />

Sets <strong>the</strong> attenuation on <strong>the</strong> attenuator to 30 dB and switches off <strong>the</strong> coupling to <strong>the</strong> reference<br />

level.<br />

Characteristics<br />

*RST value: 0 dB (AUTO is set to ON)<br />

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

Mode<br />

all<br />

INPut:ATTenuation:AUTO<br />

This command automatically couples <strong>the</strong> input attenuation to <strong>the</strong> reference level (state ON) or<br />

switches <strong>the</strong> input attenuation to manual entry (state OFF).<br />

Parameter<br />

ON | OFF<br />

Example<br />

INP:ATT:AUTO ON<br />

Couples <strong>the</strong> attenuation set on <strong>the</strong> attenuator to <strong>the</strong> reference level.<br />
