User's manual (5MB). Q&A: Q: How to hear radio stations on the spectrum analyzer? A: The SCANWIDTH has to be set at either ZERO or 0.1MHz. It sounds better on ZERO than 0.1MHz. Only noises can be heard if the scanning bandwidth is set above 0.1MHz. Local FM radio stations are mostly at frequencies from 90MHz to 100Mhz. The BAND WIDTH button should be at the up position (400kHz). Q: Does the track signal generator work at the same time when there is input signal? A: Yes. But the track signal generator will feedback noise to the spectrum analyzer itself. What you see on the screen will be greatly affected by it. Also, the generated signal is affected by input noise. The signal is most clean and stable when SCANWIDTH is set at ZERO. FM radio signals around 90Mhz 900Mhz cordless phone handset and station signals
