The VSAT Transmitter and Receiver Test Station is a low cost COTS-based test station for testing transmitters and receivers used in a VSAT (Very Small Aperture Terminal) antenna. Automated test software enables full test automation. The VSAT test station is capable of full range testing of block up-converters (BUC) and low noise block down-converters (LNB). For customers needing additional functionality, G Systems also provides full customization services.

Test Schematic

Custom software enables the test operator to select the device under test (DUT) part number and serial number and executes the test based on configured parameters for that part.  A configuration GUI enables entry and editing of DUT parameters.  At the end of each test, the software stores all results in a spreadsheet format and generates a printable report in PDF format.


Additionally, software screens instruct the user during the calibration measurement process.
