All Signal Hound devices are calibrated to better-than-box specs during production. However, if you require a signed calibration certificate with a printed packet of calibration data, you will need to select it below:

The Signal Hound USB-SA44B is a Software Defined Radio (SDR) optimized as a 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 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.

We offer a two year manufacturer’s warranty and a 30 day Money Back Guarantee. If you are not completely satisfied with your Signal Hound, return it within 30 days for a full refund minus shipping cost.

Please note: The Signal Hound is not intended for use with spread spectrum signals. If your modulated signal is wider than 20 MHz, amplitude accuracy is not guaranteed. Frequency-hopping and pulsed signal measurements may require special settings.
