User Manual 1321.1011.02 ─ 06.00
Parameters:
<AttenMode>
LDIStortion | LNOise
LDIStortion
Selects "Auto Low Distortion" mode.
LNOise
Selects "Auto Low Noise" mode.
*RST:
LDIS
Example:
INP:ATT:MODE LNO
Sets the attenuation mode to Auto Low Noise.
INPut:ATTenuation:AUTO
<State>
This command couples and decouples input attenuation to the reference level.
Parameters:
<State>
ON | OFF
*RST:
ON
Example:
INP:ATT:AUTO ON
Couples the attenuation set on the attenuator to the reference
level.
INPut:GAIN:STATe
<State>
This command turns the preamplifier on and off.
Parameters:
<State>
ON | OFF
*RST:
OFF
Example:
INP:GAIN:STAT ON
Activates the preamplifier
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.
