  • Two rather different communications testers.

    I spotted 2 Hewlett Packard 3784A Digital Transmission Analyzers on Ebay recently. I thought they might be interesting for the boxes but when I looked more closely I realised that they were a bit more interesting because they should be able to talk to…

  • RT1-M Digital Audio Analyser

    I got quite lucky (I think) at an auction a couple of weeks ago and got a lot of three Neutrik RT1-M digital audio test boxes for £99 (including commission and VAT). It's quite an old design with a slightly quirky instruction set, but very cheap for…

  • HP 3325A Synthesizer/Function Generator

    I recently bought this instrument on Ebay - it's quite an old design and if you fancy one the 3325B might be a better bet since it has a much more modern processor and a few extra functions (but will cost more). It was first released in 1979, at $3000…
