Enables or disables signal amplification inside the instrument for an input.
Parameter syntax: Preamplifier<Input>
where Input is one of A, B, D, E. For example: PreamplifierA
Possible values: Off, On
Default value (RST condition): Off
Description
Allows to amplify input signal. It is recommended to turn amplification on only if input signal has low amplitude.
Off - Preamplifier in off for corresponding input
On - Preamplifier in on for corresponding input
Correct auto-trigger operation and voltage measurements are possible for the following input signal voltage ranges depending on attenuation and preamplifier settings.
| Preamplifier=off | Preamplifier=on | |
|---|---|---|
| Attenuation=1x | -5 … +5 V | -1.5 .. +1.5 V |
| Attenuation=10x | -50 ... +50 V | -15 .. +15 V |
| Attenuation=Auto | -50 ... +50 V | -1.5 .. +1.5 V |
