HP / Agilent 53152A 46 GHz CW Microwave Frequency Counter

The HP/Agilent 53152A is a microwave frequency counter delivering precision measurements up to 46 GHz across dual channels. Channel 1 spans 10 Hz to 125 MHz with 40 mVrms sensitivity, while Channel 2 extends to 46 GHz for RF and microwave applications. The instrument combines frequency counting with simultaneous power measurement on Channel 2, eliminating the need for separate instrumentation in mixed-signal test scenarios.
