Input (AC/DC)
Toggles the RF input of the R&S ESR between AC and DC coupling.
Remote command:
INPut:COUPling
Input (1 2)
Selects the RF input the signal is applied to.
The first RF Input supports a frequency range from 9 kHz to f
range from 0 dB to 75 dB. The second RF Input is a pulse-resistant input. It supports a
frequency range from 9 kHz to 1 GHz and an attenuation range from 10 dB to 75 dB.
Attenuation levels smaller than 10 dB are not possible at RF Input 2.
With option R&S ESR-B29, the minimum frequency is extended to 20 Hz at both RF
inputs.
Remote command:
INPut:TYPE
User Port
The user port (AUX port) can transmit bit patterns in two directions, depending on the
