These settings are:
●
Offset
●
Input coupling
●
Lowpass filter (bandwidth)
●
Self-alignment
The gain or attenuation of the adapter is automatically set by the oscilloscope depend-
ing on the vertical scale.
3.5.1 Offset Compensation
The DC offset voltage is subtracted from the signal at the input of the R&S RT
‑
Z1M.
The offset is part of the vertical settings of the channel to which the adapter is connec-
ted. For details, refer to the user manual of the Rohde
& Schwarz oscilloscope.

3.5.2 AC/DC Switching
Without the adapter, the input coupling is limited to "DC" for a 50 Ω input impedance.
When the R&S RT
‑
Z1M adapter is connected to the channel input, AC coupling is also
possible. Note that the R&S ProbeMeter does not show the correct DC voltage on the
probe tip if AC coupling is active.
The coupling is part of the vertical settings of the channel to which the adapter is con-
nected. For details, refer to the user manual of the Rohde
& Schwarz oscilloscope.
3.5.3 Analog Bandwidth
The R&S RT
‑
Z1M features two lowpass filters of 200 MHz and 20 MHz. The filters
reduce bandwidth and thus noise during the measurement.
