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 50
Ω
The R&S
ESRP provides an RF input for connection of a device under test (DUT) to
the R&S
ESRP. The DUT is connected to the RF Input via cable and an approriate
connector (for example a male N connector).
The RF Input supports a frequency range from 9
kHz to f
max
and an attenuation range
from 0
dB to 70
dB.
With option R&S
R&S
ESRP-B29, the minimum frequency is extended to 10
Hz.
Risk of instrument damage
Do not overload the input. For maximum allowed values, see the data sheet.
For AC-coupling, a DC input voltage of 50
V must never be exceeded. For DC-cou-
pling, DC voltage must not be applied at the input. In both cases, noncompliance will
destroy the input mixers.
When measuring unknown signals, do not use a 0
dB attenuation level. Otherwise, the
input mixer may be damaged or destroyed.
PROBE POWER
The R&S
ESRP provides two connectors to supply accessories like transducers or
probes with power.
