The 71210C microwave spectrum analyzer provides full sweep from 100 Hz to 22 GHz. Above 2.9 GHz the built-in preselector is dynamically tracked, ensuring optimum amplitude accuracy and flatness. Fundamental mixing provides sensitivity of -139 dBm at 1 GHz and -133 dBm at 22 GHz, allowing fast, accurate spurious-response measurements. As part of the Modular Measurement System (MMS) family, you can choose a configuration that best meets your requirements in performance, size, and price. Adding accessories such as a preamplifier or tracking generator is very easy. For automated testing, the Keysight 70000 series of spectrum analyzers are compatible with the 8566B. Their proven reliability and repeatability allow a three-year calibration cycle, giving you a very low lifetime cost.
