Preparing for first article tests
The first article of the Antenna Unit (AU) will arrive at the Production Engineering and Test (PET) test site, located at EISCAT in Kiruna, in July. After installation by the vendor, ECRIEE, the initial AU tests will verify dimensions, cabling, electrical installations and the environmental control system (cooling, heat, etc). For the RF tests, the AU will be equipped with Solid State Power Amplifiers (SSPA) – from Japan which are controlled by the in-house developed Pulse and Steering Control Unit (PSCU) system.
In preparation for those tests, the project staff, here represented by Robert Juhlin and Assar Westman, have setup parts of the transmitter system at our offices for pre-tests. For synchronisation of the individual channels, a white-rabbit system has been deployed. The control system is GUI based.
The PSCU logic and amplifiers used here will not be the ones used in the final system. Both the PSCU and the transmitter system are sourced via external contracts.
