General Radio Type 874-VQ Voltmeter Detector, New In Box

General Radio Type 874-VQ Voltmeter Detector, New In Box.

A GR874 voltmeter detector is used as a general purpose rf level detector with a dc indicator or as a modulated signal detector with a sensitive amplifier. It can be inserted into a 50 Ω line without introducing appreciable discontinuity or, with a GR874 50 Ω termination, it can be used as a matched detector to terminate a line.

• 874-VQ non-locking, 874-VQL locking
• Frequency: 500 kHz to 2 GHz when used as a matched detector
• SWR: <1.1 at 1 GHz, <1.2 at 2 GHz 
• Input voltage: 2 V maximum
• Impedance: 50 Ω, bypass capacitance: ~300 pF, diode: 1N23B

While this is shiny-new in the box, due to its age it is being sold as is, for parts or repair.
