4.4 ghz spectrum analyzer and measuring receiver

only $919




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抎 expect in a unit many times its cost.

the original usb-sa44 has sold out! our new "b" model has added 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 one 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.

discuss the signal hound at our new signal hound discussion group on facebook

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.
