2 Monitoring Receiver R&S® ESMB
General
The R&S ESMB is a monitoring and test 
receiver for all radio detection and 
radiomonitoring 
tasks in line with ITU-R, 
and for radio investigation services. The 
compact and sturdy design combined 
with low weight makes the R&S ESMB a 
versatile and universal unit for stationary 
and mobile use. 
Applications
The following measurements in line with 
ITU-R specifications can be performed by 
the R&S ESMB:

Operation
The Monitoring Receiver R&S ESMB 
features full remote control capability as 
well as manual control via the front panel.
The operating concept meets all the 
demands made on a state-of-the-art 
spectrum monitoring receiver, i.e. all the 
main functions such as type of modula-
tion, bandwidth, etc can easily be set 
directly via labelled keys.
Menu control is organized in priority 
levels so that signal processing is not 
interrupted by menu changes and the 
user...

Monitoring Receiver R&S® ESMB 5
Use in computer-controlled 
systems
Full use of the performance features of 
the receiver can be made in the remote-
control mode via LAN using a suitable 
PC and the Spectrum Monitoring 
Software R&S ARGUS or R&S RAMON.
R&S RAMON, which is primarily used in 
military and security applications, 
enables fast frequency detection and 
transfer to support monitoring receivers 
(concentration on interactive operation 
and signal identification). 
R&S ARGUS is intended for...
