Description
Made by Hewlett Packard, model 424A, this is a waveguide Crystal Detector, in X-Band sized guide, WR-90, 8.2-12.4GHz. I have checked thwe diode and its OK, very sensitive type, uses same diode as in the HP 423A crystal detector. BNC(F) out. Handy for the test bench! Now you can put that waveguide diectional coupler to work as a VSWR detector, or use this as an "RF sniffer" with a DVM as readout! Good condition, used.
