RF Test Gear Job Lot 41372-051 41372-052 HP Crystal Detector Cossor Untested
Item Description
A lot of four vintage RF / microwave test-gear items — avionics/radar test-bench accessories and HP coaxial parts. Sold together as an untested spares-or-repair bundle.
Sold as untested — not calibrated. These are ex-equipment surplus items. Some carry lapsed “Cal Due” / “calibration invalidated” stickers. I have no calibrated RF bench to verify their performance, so they are sold strictly as-is for spares or repair, with no functional or calibration guarantee. Sold for their part value to someone who knows these items.
The lot comprises (as marked on the items):
- Matching Network 41372-051 — inline RF unit, BNC connectors.
- Impedance Changer 41372-052 — inline RF unit, BNC connectors (matched sibling to the above).
- Hewlett-Packard Crystal Detector — knurled coaxial diode detector, marked HP, Made in USA.
- HP coaxial component — serial approx. 6531311, orange band, with lapsed Cal Due sticker (function not verified — see photos).
- Cossor Electronics RF cal lead / probe — cabled probe with “removing this invalidates calibration” wrap and Cal Due dot.
Please study the photographs — they show the actual items and all readable markings. Buy on the basis of what is visible, not on any assumed specification.
Cosmetic condition: used ex-service — general wear, tarnish, sticker residue and handling marks throughout, as photographed.
