other then big, noisy and somewhat of a power hog, they to me are one of the best bargains out there if you don't have a big budget.
HP Journal that talks about them http://www.hparchive.com/Journals/HPJ-1974-06.pdf if your not in a hurry and you use GPIB or think you will in the future, look for option 12. I have seen fully working 5345As go for as little as $25 on the E. One day I went to do a local pickup of a piece of Tek gear and the guy had about 10 5345A's all not working from a DOD sale. I went home with a full pickup for $50. 001 - Room Temperature Time Base 010 - General Purpose Interface ( gpib format, talk only) 011 - General Purpose Interface (Digital I/O plus control of all functions except input amplifier) 012 - General Purpose Interface (similar to option 011, but adds slope and level control) Where I will never give mine up is the combination of the 5355A plug-in and one of the 5356A/B/C heads. It brings the counters input as close as you want to your work. You do have to be careful on getting a non damaged head There is 5245A that will take you to 4Ghz. and an App note http://www.hpmemory.org/an/pdf/an_173.pdf Lastly there is the HP10590A plug-in adapter that lets you use the 5245 plug-ins. For me I use the Video plug-in and one that I made myself from a gutted one. Lastly there are S/N ranges but I can't remember them .. -pete On Sat, Dec 25, 2010 at 3:17 PM, Burt I.
