Product Description

Signal Hound USB-SA44B

BRL Test is your authorized signal hound distributer.

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. Analyze with state of the art sensitivity, accuracy and dynamic range that 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. 
Upgrade to scalar network analyzer when you couple the USB-SA44B with the USB-TG44A (combo savings price $1472.46)
