Connectors on the Front Panel

This section describes the front connectors and interfaces of the R&S ESR. Optional
connectors and interfaces are indicated by the option name in brackets. Most connec-
tors on the front panel (except for USB) are located at the bottom right-hand side.
EMI impact on measurement results
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated electromagnetic interference (EMI):
●
Use suitable shielded cables of high quality. For example, use double-shielded RF
and LAN cables.
●
Always terminate open cable ends.
●
Note the EMC classification in the data sheet.
USB
The front panel provides two female USB connectors to connect devices like an exter-
nal keyboard or mouse. You can also connect a memory stick to save and restore
instrument settings and measurement data.
NOISE SOURCE CONTROL
The noise source control female connector is used to provide the supply voltage for an
external noise source, for example to measure the noise figure and gain of amplifiers
and frequency converting DUTs.
Conventional noise sources require a voltage of +28 V in order to be switched on and
0 V to be switched off. The output supports a maximum load of 100 mA.
RF INPUT 50Ω
The R&S ESR provides two RF inputs for connection of a device under test (DUT) to
the R&S ESR. The DUT is connected to the RF Input via cable and an approriate con-
nector (for example a male N connector).
The first RF Input supports a frequency range from 9 kHz to f
range from 0 dB to 75 dB. The second RF Input 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.
