Because I have GR bridges, detectors, oscillators etc I also need the accessoires. GR used their famous unisex GR-874 connector. A brilliant system suited for very high frequencies. I’m always on the hunt for this sort of things.
An attenuator to couple power from a transmission line to a spectrum analyser or RF voltmeter, or scope etc. Some fixed attenuators, T and L pieces, inline probe pick-offs, airline and several adapters to GR-874
This is a GR-MR mixer, a brand new GR-874 locking version and 4 pieces off high percision airline. To bad I do not have any GR-900 adapters because that is what they used on these things.
A gift from my friend Mans and brought here by my friend Eric who found it. Two General Radio Trombones. That is a linestretcher used for instance to match the phase between a VNA test and reference receive. They were also used for the GR admittance meter. The top one is GR, the second one is a rebranded Philips and they mounted a centimeter on it. The Philips was in bad shape. The inner tubes where stuch because someone took it apart and mounted it wrong. This has damaged the inner springcontacts in one tube and that finger was stuck in de innertube. I need to replace connector innerpin that was bend. The GR one is in perfect state.
