R&S

ESR

34User Manual 1175.7068.02 ─ 12

With option R&S ESR-B29, the minimum frequency is extended to 10 Hz at both RF

inputs.

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 ESR provides two connectors to supply accessories like transducers or

probes with power.

The probe power connector on the left supports supply voltages of ±10 V and ground.

The maximum permissible current is 200 mA. This probe power connector is suitable,

for example, for transducers from Rohde & Schwarz.

The probe power connector on the right 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 Agilent.

AF OUTPUT

Headphones equipped with a miniature jack plug can be connected to the AF output

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.

Risk of hearing damage

Before putting on the headphones, make sure that the volume setting is not too high to

protect your hearing.

Tracking Generator Output (GEN OUTPUT 50 Ω, Option R&S FSV-B9)

The R&S ESR is equipped with an optional tracking generator and therefore provides a

tracking generator output connector.
