MICROWAVE SPECTRUM ANALYZER - The Agilent 71200C microwave spectrum analyzer offers a wide variety of price and performance options and a frequency range of 50 kHz to 22 GHz. The standard configuration gives unpreselected microwave capability at just over the price of an RF analyzer with similar performance in terms of speed, phase noise, and feature set. For RF measurements and microwave signals, this analyzer may be ideal. If measuring known signals in a controlled environment such as manufacturing, this analyzer offers high performance at an economical cost. For coverage to 325 GHz, add an Agilent 70907B external mixer interface module. The Agilent 70620B preamplifier modules can be used with the 71200C spectrum analyzer for improved sensitivity. Option 001 on the Agilent 70620B provides coverage down to 100 kHz.
