Product Description

Compact

The CA7801 is a full featured wideband HF receiver in a compact form-factor with low power consumption.

True Wideband Stare

The CA7801 has the ability to continuously digitise the entire HF spectrum in real time.

Built in Preselector

Preselection for wideband HF  improves immunity to in-band interference

Digital Drop Receivers

Configure multiple digital drop receivers (DDRs) for simultaneous processing of wanted signals.

Customisable DSP Resources

Add software defined functionalist to dedicated customisable digital signals processing resources.

Phase Coherent

Synchronise multiple CA7801 units for Super Resolution DF, MIMO and and advanced signal enhancement techniques.

Precision Time-Stamping

Precision time-stamping with for TDOA (Time Difference of Arrival) Geo-Location.

Advanced Architecture

  • Robust performance in strong signal environments with integrated sub-octave preselector
  • Selectable modes: normal mode or high linearity mode, allowing configuration for optimum performance
  • Direct Digitisation topology for full HF spectrum capture
  • Extremely stable group delay and absolute delay characteristics - crucial for enduring DF accuracy
  • Capable of synchronising with multiple units for phase coherent operation

Full Bandwidth Processing

The CA7801 digitises the entire HF band. It is capable of streaming full bandwidth VITA 49 I/Q data of 10 GigE Ethernet in real time. Full remote control functionality is implemented with a simple SCPI command set.

Customisable Digital Signal Processing

On-receiver software defined functionality can include: channellisation, demodulation, and automatic signal detection. For system integrators, the CA7801 has dedicated processing resources enabling upgrades with software defined functionality.

Rugged Carrier Chassis

The CAM91579 Dual Receiver Carrier Chassis is the recommended option for mounting multiple receivers into 19" equipment racks for mobile or static use. The rugged carrier chassis CAM91579 has been designed to meet MIL-STD-810G in the following categories:

  • High Temperature (Method 501.5, Proc. II, Cat. A2 (ambient))
  • Low Temperature (Method 502.5, Proc. II, Cat. C1 (ambient))
  • Vibration (Method 514.6, Proc. I, Cat. 4)
  • Acoustic Noise (Method 515.6, Proc. 3)
  • Shock (Method 516.6, Proc. VI)
