HP 5245 L Nixie Counter Part 7: HP 5264 Preset, HP 5262 Time Interval, HP 5257 Transfer Oscillator

We test a pile of new plugins, and fix the king of them all: the HP 5257A 18 GHz Transfer Oscillator. While we are at it, we demo the HP 5264A Preset Unit and the HP 5262A Time Interval Unit. This completes our repairathon No kidding, we repaired them all, the main counter and 10 plugins 5245L Repairathon Playlist: Further documentation on my website: Stuff that supports the channel: Amazon links for the tools I use in the lab (supports the channel if you buy from there) Channel merch on Teespring: Support us on Patreon: Our lovely sponsors PCBWay: fast turn PCBs, ElectroRent: Keysight: test instruments: Samtec: connectors: R D Microwaves: Get more technical info on the companion site: Contact info: 00:00 Recap of previous episodes 00:43 New pile of plugins 01:47 HP 5264A Preset Unit Plugin Test 04:11 HP 5262A Time Interval Unit Test 05:53 HP 5257A Transfer Oscillator Test 08:05 Transfer Oscillator Explanation 13:27 Fault, 1 Debug 20:00 Fault, 2 Debug 25:14 It works again 26:41 Now part the Apollo setup
