2.3.1 Buffer amplifier box
The buffer amplifier box contains active circuitry to attenuate, amplify or filter the
incoming signal and pass it to the 50 Ω input of the oscilloscope. There are no controls
or indicators on the buffer amplifier box.

2.3.2 Probe interface

The R&S RT‑Z1M is designed for connection to the Rohde & Schwarz probe interface
of the oscilloscope. The interface provides also a USB interface and supply voltages
(+5 V USB, +12 V high power). It transmits analog signals and digital data simultane-
ously.
The output of the R&S RT‑Z1M is connected to the oscilloscope. It consists of male
precision 7 mm (276 mil) coaxial connector and six pogo pins to ensure a thorough
connection.
Probes are connected to the input of the R&S RT‑Z1M. The Rohde & Schwarz probe
interface at the input provides the power supply and USB interface to recognize and
support active probes. It has also a contact ring to recognize a passive probe by its
readout pin. In any case, the probe is recognized automatically by the oscilloscope.
