I decided to try to design a simple homemade spectrum analyzer, based on TI/Chipcon CC1100.
The SA will use the reading of RSSI from CC1100, covering 800-928MHz, and an input mixer to convert an input spectrum of 1-128MHz to 800-928MHz.
The problem - the minimum configurable bandwidth (RBW) for CC1100 is 58kHz, which is very high.
An SA with such RBW could be used for real measurements?
How can I reduce thid bandwidth?
Could you recommend a similar chip that can be configured for lower IF bandwidth, like 1kHz?
Thanks
