PAN-1000
Plug-in units (modules)

PAN-1000 was a high-end intercept receiver in a 19" rackmount case, designed and built in the early 1980s by the Dutch Radar Laboratory (NRP), for use by the Dutch Radio Monitoring Service. This page provides detailed information and images of each of the plug-in units, or modules of the main unit of the PAN-1000. The the list below to jump straight to the desired section.

UNDER CONSTRUCTION — This page is under construction and currently acts as a placeholder for future descriptions and information about the individual modules of the PAN-1000. The page is far from complete, but additional information will be added in due course. Photographs are already available.
Modules
The table below lists all modules of the PAN-1000 system. Note that only modules 1—19 are part of the main unit. Module 20 is the power supply unit (PSU) and is housed in a separate rack. The other modules are the peripherals. Each module is described in more detail further down this page. The corresponding PCB numbers are displayed in grey in the title of each section.

1. Input selector   83161
The input selector is located at the far left of the upper rack. It connects the antenna to one of the six RF converters to its right (modules 2-7). It consists of a high quality 6-position RADIALL coaxial selectors, and suitable electronics to select each of the six channels.

It also contains a 40dB attentuator that can be inserted between the antenna and the relay by means of two RADIALL coaxial relays.

10. IF Amplifier and Demodulator   82055
This module takes the 10.7 MHz signal from the 50 MHz IF stage (module 9) and splits it into two separate branches: one for the FM demodulators and one for AM and SSB demodulators.

The FM branch – built around a CA3089 – is further split into a wideband (WBMF) path and a narrowband (NBFM) path, with the WMFM section delivering the signal for a pilot tone detector. When a stereo signal is sensed, the letter 'S' will be shown on the display.
