HP 5245L 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 repair-a-thon! No kidding, we repaired them all, the main counter and 10 plugins! 5245L Repair-a-thon 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, - Electro-Rent: - 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!
