Pendulum Instruments introduces the GSG-L1, a very cost-efficient GPS signal generator for production test or R&D purposes. GSG-L1 is suited for fast, efficient and low-cost production line testing of mobile phones with integrated GPS-receivers. Thanks to the very wide RF level range from –73 to –150 dBm with 0.1 dB resolution, the sensitivity of all types of integrated GPS receivers can be verified with a minimum of delay.
