Key Facts

The compact and modular VLF-HF receivers are ideal for use in stationary, mobile and remote receiving systems. Due to the modern and flexible concept, the receivers can be used as communication receivers in communication networks and for fast search, scanning, radio detection and radiomonitoring tasks. Moreover, the units are optimally suitable as highperformance frontend units (e.g. for special post-processing applications (COMINT) as well as for DF systems.

The R&S® Series 890 VLF-HF Receivers use digital signal processing (DSP) for IF, demodulation and AF. The DSP, equipped with a very powerful microprocessor, offers a variety of additional features to the user such as automatic signal processing, signal optimization and high operating convenience. All this significantly improves the attainable reception quality.

The very compact ½ 19" single receivers or 19" (rackable) single or dual receivers allow any type of system combinations in the form of operator positions or handoff receivers (master-slave operation). Handoff or remote receiving operation over any distance is possible without any constraints using master (R&S EK896)/slave (R&S EK895) concepts.

Due to the excellent RF characteristics and the uncomplicated and full remotecontrol capability the R&S® EK895 is suitable for all civil, administrative and military shortwave applications. The R&S® EK895 is an ideal choice for receiving systems which have to fulfill extremely high reliability requirements, in particular under harsh environmental and EMC conditions.

Main features

  • Digital signal processing (DSP) for convenient and versatile operation
  • Clear-cut front panel for simple, menu-guided operation
  • Realtime remote control or masterslave mode
  • Well-proven system concept
  • Excellent price/performance ratio
  • Extremely reliable operation under harsh environmental and EMC conditions
  • Application-specific options and accessories available

Brief Description

The R&S® EK895 is a powerful VLF-HF receiver which is a top-end product benefiting from many years of experience in this field. Due to the advantages of digital signal processing embedded in the R&S® EK895 receiver, a number of additional features and operator convenience have been added. The operational features additionally incorporated into the R&S® EK895, such as preamplifier (PREAMP), noise blanker (NB), squelch (SQ), notch filter (NOTCH) and passband tuning (PBT), are selected in submenus using softkeys. If one of these features is active, a bargraph appears on the display above the relevant inscription (PREAMP, NB, SQ, NOTCH, PBT).

Clearly organized, menu-guided selection and programming of the receiving settings ensure excellent processing and handling of the received signal content. Due to its full system compatibility, the receiver provides the basis for extremely economical customer-specific solutions.

The R&S® EK895 thus fulfills the requirements for versatile use in voice receiving and any kind of data communication systems as well as for all radiomonitoring, radio detection and radio intelligence (COMINT) applications.
