INPut:IMPedance
<Impedance>
This command selects the nominal input impedance. The set impedance is taken into
account in all level indications of results.
The setting 75 Ω should be selected, if the 50 Ω input impedance is transformed to a
higher impedance using a 75 Ω adapter of the RAZ type (= 25 Ω in series to the input
impedance of the instrument). The correction value in this case is 1.76 dB = 10 log (75
Ω / 50 Ω).
Parameters:
<Impedance>
50 | 75
*RST:
50 Ω
Default unit: Ohm
Example:
INP:IMP 75
Sets the input impedance to 75 Ohms.
INPut:IMPedance:PAD
<PadType>
This command selects the matching pad connected to the R&S Spectrum Rider.
Parameters:
<PadType>
RAM | RAZ | HZTE
Example:
INPut:IMP 75;PAD RAZ
Selects 75 Ω input impedance and the R&S RAZ as the match-
ing pad.
