4.1.5
RF Input 50
Ω
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 connector (for example a male N connector).
The first RF Input supports a frequency range from 9
kHz to f
max
and an attenua-
tion 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.
With option R&S
ESR-B29, the minimum frequency is extended to 10
Hz at both
RF inputs.

Probe Power
The R&S
ESR provides two connectors to supply accessories like transducers or
probes with power.
The probe power connector with five pins supports supply voltages of ±10
V and
ground. The maximum permissible current is 200
mA. This probe power connec-
tor is suitable, for example, for transducers from Rohde
&
Schwarz.
The probe power connector with three pins supports supply voltages from +15
V
to -12.6
V and ground. The maximum permissible current is 150
mA. This probe
power connector is suitable, for example, for high-impedance probes from Agi-
lent.
4.1.7
AF Output
Headphones equipped with a miniature jack plug can be connected to the AF out-
put female connector. The internal impedance is 10
Ω. The output voltage can be
set by using the volume control to the right of the female connector. If a plug is
connected, the internal loudspeaker is automatically switched off.

Tracking Generator Output (Optional)
The R&S
ESR is equipped with an optional tracking generator and therefore pro-
vides a tracking generator output connector.
