Operating instructions

INPut Subsystem R&S ESCI
1166.6004.12 6.110 E-1
INPut<1|2>:LISN:PEARth GROunded | FLOating
This command selects the setting of the protection earth of the V-network.
Example: ":INP:LISN:PEAR GRO"
Characteristics: *RST value: GROunded
SCPI: device specific
Mode: R, A
INPut<1|2>:UPORt[:VALue]?
This command queries the control lines of the user ports.
Example: "INP:UPOR?"
Characteristics: *RST value: -
SCPI: device-specific
Modes: all
This command is a query and therefore has no *RST value.
INPut<1|2>:UPORt:STATe ON | OFF
This command toggles the control lines of the user ports between INPut and OUTPut.
Example: "INP:UPOR:STAT ON"
Characteristics: *RST value: ON
SCPI: device-specific
Modes: all
With ON, the user port is switched to INPut, with OFF to OUTPut.
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: conforming
Mode: all
INPut<1|2>:GAIN:STATe ON | OFF
This command switches on the preamplifier for the instrument. The switchable gain is fixed to 20
dB..
In analyzer mode, the command is only available, if the preselector measurement has been
activated.
Example: "INP:GAIN ON" 'Switches on 20 dB preamplification
Characteristics: *RST value: OFF
SCPI: conforming
Modes: R, A
