 ===== Operation ===== ===== Operation =====
-The [[VHF]] [[UHF]] receiver ​system Rohde & Schwarz ET001 carried ​the Swiss Army designation ​E-652 when used as monitoring ​receiver.+The ESM 500 VHF / UHF receiver ​in a 19” cabinet can be used as a monitoring receiver and replaced ​the [[E-652|ESM2]] ​receiver ​in the [[P-736]] VHF / UHF direction finder ​.
  
-{{:​images:​e-652-rohde-schwarz-esm2-front.jpg?​400 |P-728: Empfänger ESM2}} ​The VHF-UHF receiver **ESM2** covers 25 - 1000 MHz in nine band segments, it has an analog dial with a conventional tuning knob, reception ​modes [[AM]], [[FM]] and PULS are selectable. The IF bandwidths are 15, 30, 250 kHz and 1 MHz, the receiver has several AGC and MGC options. +The receiver covers the entire ​VHF UHF range from 20 - 1000 MHz , for SSB reception, the tuning step sizes can be switched ​down to 10 Hz.
- +
-The frequency ​can also be controlled with the frequency controller **EZK** with an up / down tuning switch featuring different tuning speeds; the digital frequency display with a resolution of 1 kHz is part of the frequency controller. The receiver can be controlled alternatively via TTL signals with BCD code or in master-slave mode from another receiver. +
- +
-{{:​images:​e-652-rohde-schwarz-ezp-front.jpg?​400 |P-728: Sichtgerät EZP}}  In the panoramic display **EZP**, a smaller or wider frequency range at the level of the second IF of 10.7 MHz can be displayed.+
  
 +The 99 memories can also be written externally via an IEC / IEEE bus or RS232C interface, a scan function allows to scan the memory channels - this functionality anticipates the possibilities found in a scanner receiver from the nineties. ​
