Condition
Used and in good shape on visual inspection, with both front-panel lock-down screws missing. It was working when last stored as a spare, and it has been powered on here but not tested beyond that. Front panel markings legible: AMX, Model 8224, Busy, Input, Enabled, channels 1 through 8, LLD, Signal, Gate, Canberra; rear: PI, ADC, MCA, EXP, Trigger. The unit pictured is representative of stock.
Selling online since 1999. It ships from our Idaho warehouse the same or next business day.
Product Overview
Canberra's Model 8224 AMX is an analog multiplexer in Nuclear Instrumentation Module (NIM) form. Eight BNC inputs on the front each have a red Busy lamp and a green Enabled lamp, and the module routes them to a single Signal output with a Gate connector beside it. That lets several detector channels share one ADC and multichannel analyzer instead of each needing its own.
Key Features
- Double-width NIM module, takes two bin slots
- Eight BNC signal inputs, numbered 1 through 8
- Busy and Enabled lamp for each input
- Signal and Gate BNC connectors and an LLD lamp
- Rear ribbon headers labeled PI, ADC, MCA and EXP
- Rear BNC Trigger connector
- NIM module with the standard NIM power connector on the rear
Applications
- Feeding up to eight detector chains into one ADC and analyzer in a counting lab
- Replacing a failed 8224 in an existing multi-detector spectroscopy system
- Holding a spare multiplexer in the rack for a system that cannot sit idle
Frequently Asked Questions
How many inputs does it have?
Eight, on BNC connectors, each with its own Busy and Enabled lamp.
Are the front lock-down screws included?
Not included. Both are missing.
What am I taking on with this module?
A used 8224 that worked when it was stored, has powered on here, and has not been run through a full test. Plan on supplying two panel screws. The photos are of this module. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Eight detectors, one analyzer, and a module that decides who gets to talk. Give it room in a NIM bin and let the lamps sort out the line.
