Great to hear. Cast out those batteries! Something with a 10 year life doesn't belong in a Tek scope. Tektronix made a mistake in my opinion using these Dallas Lithium NVRAMs. I've designed equipment

Thank you for brightening my day! md

I have installed a RAMTRON FRAM FM1608-120-PG device in a 2465B (socketed in case it didn't work). So far it works beautifully. I had to perform all CAL procedures since the device was blank. I

Hi Andy, Others may call me careless in my approach to firing up an old 555, but I would just plug it in and turn it on. It is pretty well fused and I would not expect any to blow anyway. You can not

First, does there exist a front cover for the 492 Spectrum Analyzer, and, if it does, where can I get one ? Thanks, Dick, W1KSZ ps: santa came early !!

Hi Andy, I will try to help you with some of your questions: be unexpected effects (underload)? You will have an unexpected effect - it won't work. The AC for the power supply, as well as its filament

Hi all, There used to be such a thing as an electromechanical chopper (AKA vibrator), kind of like a relay tuned to operate at many 100's of Hz, or faster. Airpax was a popular manufacturer. Tek used

Hello all. Does anyone in the group know the type of coax Tek used for part number 012-0649-00? Thanks, Joe

The interesting thread about phase shift reminds me of a rule of thumb I have been using for years. 'ELI the ICE man'. Voltage (E) is before Current (I) in an inductor (L). Current is before Voltage

Hi all, recently got my hands on a 555 System in unknown working condition (probably been stored 10+ years). Can anybody here give me good hints from experience on bringing this up without risking

I'm lost with you going down too deep into details, right hand and left hand rule.... Back from school times I just simple memorized (sometimes it's helping to memorize!) - phase shift between AC
