LabSat 3 Wideband has three bandwidth settings: 56 MHz, 30 MHz and 10 MHz.
The bandwidth of the GNSS signals varies, for example a GPS L1 C/A code signal has a bandwidth of 24 MHz. However, due to the signal design a bandwidth of 9.66 MHz will capture enough data to allow the receiver under test to acquire it, track and navigate.
Other signals with a different signal design like Galileo E1 PRS signal has a bandwidth of 46 MHz and a signal design spread across the bandwidth. They require a higher bandwidth to be recorded.
