Compact Receiver ESMC 3
ESMC is equipped with demodulators 
for AM, FM, LOG and PULSE modes. 
SSB reception for LSB/USB and A1 is 
optional. The log demodulator allows a 
dB-linear level indication over 9 dec-
ades. Average value or peak weighting 
may be selected. The absolute accuracy 
of the level display is further improved 
by taking into account the frequency re-
sponse of the preselection filter and the 
tolerances of the log amplifier in the 
measurement of the signal level. 
ESMC may be equipped...

Real-time spectrum display 
with EPZ 513
The external Spectrum Display 
EPZ 513 provides highly versatile dis-
play modes. An analog CRT guaran-
tees display in real time. 
RF mode 650 MHz within 50 ms
In this mode the tuner section of ESMC 
is directly controlled by the EPZ513. 
The period of the sweep is 50 ms, inde-
pendent of the span. 
The spectrum is displayed on the screen 
within the tuner range. A superimposed 
marker indicates the frequency to 
which the receiver has...

ESMC-RAMON – access to 
computer-aided radiomonitoring
Compact radiomonitoring system
With its favourable price, ESMC-
RAMON is an ideal compact radio 
monitoring software. It is configured to 
control one ESMC and can be expand-
ed to set additional ESMC and 
ESM500 slave receivers to perform ra-
diomonitoring and radiosurveillance 
tasks.
The system provides three operating 
modes:
Static mode: the receiver can be 
tuned for monitoring
Search mode: the receiver scans...
