R&S ESU
INPut<1|2>:IMPedance 50 | 75
This command sets the nominal input impedance of the instrument. 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 (75Ω / 50Ω).
Example:
"INP:IMP 75"
Characteristics: *RST value: 50 Ω
SCPI: conform
Mode: R, A
INPut<1|2>:MIXer[:POWer] <numeric value>
This command defines the desired power at the input mixer of the R&S ESU. On any change to the
reference level the RF attenuation will be adjusted in a way that makes the difference between
reference level and RF attenuation come as close to the desired mixer level as possible.
Example:
"INP:MIX -30"
Characteristics: *RST value: - 25 dBm
SCPI: device-specific
Mode: A
INPut<1|2>:MIXer:AUTO ON | OFF
This command enables/disables the automatic setup of the mixer level.
Example:
"INP:MIX:AUTO ON"
Characteristics: *RST value: ON
SCPI: device-specific
Mode: A
INPut<1|2>:PRESelection[:STATe] ON | OFF
In analyzer mode, this command switches the preselection on or off.
In receiver mode, the preselection is always switched on and cannot be switched
off.
Example:
":INP:PRES:STAT ON"
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
