I
NPut<1|2>:ATTenuation:AUTO
This command automatically couples the input attenuation to the reference level (state ON) or
switches the input attenuation to manual entry (state OFF).
Parameter
ON | OFF
Example
INP:ATT:AUTO ON
Couples the attenuation set on the attenuator to the reference level.
Characteristics
*RST value: ON
SCPI: conform
Mode
all
INPut<1|2>:GAIN:STATe (option RF Preamplifier, B22)
This command switches the preamplifier on or off. The preamplifier only has an effect below
6 GHz.
Parameter
ON | OFF
Example
INP:GAIN:STAT ON
Switches on 20 dB preamplification.
Characteristics
*RST value: OFF
SCPI: conform
Mode
A, NF, CATV, WCDMA, CDMA, EVDO
INPut<1|2>:IMPedance
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  should be selected, if the 50  input impedance is transformed to a higher
impedance using a 75  adapter of the RAZ type (= 25  in series to the input impedance of
the instrument). The correction value in this case is 1.76 dB = 10 log ( 75 / 50).
Parameter
50 | 75
Example
INP:IMP 75
