SA44B-DATASHEET

Product Description

The Signal Hound USB-SA44B is a Software Defined Receiver (SDR) optimized as a narrow-band real-time spectrum analyzer. It is compact, simple to use, and an effective troubleshooting tool for general lab use, engineering students, ham radio enthusiasts, and electronics hobbyists. Using recent innovations in RF technology, the Signal Hound has the sensitivity, accuracy and dynamic range you’d expect in a unit many times its cost.

The USB-SA44B has a preamplifier for improved sensitivity and reduced LO leakage. There is also a thermometer for temperature corrections, allowing accurate amplitude measurements over the entire operating temperature range.
