Proprietary Information

2. The QR026 High Sensitivity VME Tuner
The QR026 Tuner integrates a 17 channel pre-selector, a high sensitivity receiver, a control module and a fast switching synthesiser based on Direct Digital Synthesis technology into a compact (19 in x 2U) unit.
The QR026 is suitable for ESM, ELINT and RWR applications across airborne, naval and land based platforms.
The individual VME modules are available for integration into a customer – supplied rack.
Some of the data in subsequent slides refers to the QR019 Receiver. The QR019 is a 3 channel system utilising the same modules as the QR026, which shows equal performance.
