When testing Global Navigation Satellite Systems (GNSS)-reliant equipment, many manufacturers and chipset integrators will use record and playback solutions to reliably test real-world signal environments in the lab.
However, depending on what bit depth your record and playback system (RPS) is capable of, the process of converting analog signals into digital testing files could create a flawed image of a signal environment – and compromise the fidelity of your testing efforts.
This paper explains how this happens; the impacts of using an RPS with low bit depth; and what manufacturers and chipset integrators can do to accurately recreate signal environments and ensure they test against authentic real-world conditions.
