Input Coupling
The RF input of the R&S ESW can be coupled by alternating current (AC) or direct cur-
rent (DC).
Note that the "Input Coupling" feature is only available for input 2 when the pulse lim-
iter is turned off. When the pulse limiter is on, the input is always DC coupled.
AC coupling blocks any DC voltage from the input signal. AC coupling is activated by
default to prevent damage to the instrument. Very low frequencies in the input signal
can be distorted.
However, some specifications require DC coupling. In this case, you must protect the
instrument from damaging DC input voltages manually. For details, refer to the data
sheet.
