Input (AC/DC)
Toggles the RF input of the R&S
ESR between AC and DC coupling.
Remote command:
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
max
and an attenuation
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:
User Port
The user port (AUX port) can transmit bit patterns in two directions, depending on the
actual selected signal direction. The user port is available on the rear panel when you
equip the R&S
ESR with option R&S
ESR-B5.
●
"Direction" = "In" (read only)
Opens a dialog box. Select the "Read" button to read out the user port configura-
tion. The value is displayed in the dialog box.
●
"Direction" = "Out"
Select the required bit pattern by changing the state of the individual ports ("Port
<x>").
