Parameters:
<AttenuationMode>
LDIStortion
Select "Auto Low Distortion" mode.
LNOise
Select "Auto Low Noise" mode.
*RST:
LNOise
Example:
//Select auto low noise attenuation
INP:ATT:AUTO ON
INP:ATT:MODE LNO
INPut:GAIN:STATe
<State>
This command turns the preamplifier on and off.
Parameters:
<State>
ON | OFF | 1 | 0
*RST:

INPut:IMPedance
<Impedance>
This command selects the nominal input impedance.
The selected impedance is taken into account in all level indications of results.
When you need to select a 75
Ω
impedance, the 50
Ω
impedance is transformed to a
higher impedance. A 75
Ω
matching pad is required for this transformation. The correc-
tion value in that case is 1.76
dB
=
10log(75
Ω
/50
Ω
).
