Yep, covered that in less words..... <grin> Harvey

Use a 74LS90, which is a divide by 2, and a separate divide by 10.  (This assumes a 9 Mhz can oscillator, and that it's 5.0 volts supply, and that the rest of the circuit needs a 5 volt signal. Note

Hi folks, Is there a way to tell (for example by serial number) which scopes had which version of the A5 board? I am aware of 3 variants 1) leaky surface mount electrolytics 2) through hole

Hey folks, Wondering if there is someone here who is a readout system whisperer. I have me a 7904 that wasn't working when I got it. It's a rather interesting one, with all available options

Ed has an excellent idea (as always). There could be a small issue related to the additional mixing products you would get from the harmonics of the square wave output typical of such oscillators, so

Could also get a programmable oscillator from someone like Digikey and request it be programmed for 900Khz. I think they have oscillators down to +/-15ppm for ~$5. Might need a buffer/driver. Would

The 1L10's 900 kHz crystal appears to be for an oscillator, so you could make a 9 MHz - a very common crystal frequency - oscillator and divide it by 10, if you can't find a 900 kHz one. Ed

Hi Jeff, You're right, it's absolutely meant for / suited to the P6008. I couldn't imagine, because of the relatively small BW (still 100 MHz) of the P6008, so some series inductance wouldn't harm so

Joel, I have a working mint condition 1L10 that I'm not planning to ever use. Would trade it for a working 1A4 or 1S2. Regards, John

Now, THAT's a museum piece! Please take some pics of its innards and outards when you get a chance. I'll rummage through my Mystery Box of Crystals (a cousin of Jeff's probe box) and see if by some

Thank you Ozan. It’s been a long day, but I’ll make those measurements later on or tomorrow. (I’m 9h ahead of you). Il report back as soon as it’s done. Thanks again for your help.

Welcome! I’m also somewhat new. I’ve been here less than a year I think. Nice, great and extremely knowledgeable people. They always go out of their way to help mere mortals like me. You’ve

Glad you are here. You will be amazed what you can learn from this group. -- Michael Lynch Dardanelle, AR

Raymond, The reasons that I suspect that <A> is an accessory for P6008 are: 1. the same lot of odds and ends contained a sealed Tek bag of accessories, that appears to have the same part in it along

Hello all. I have a Tektronix 475 that I have been working on. I've got it repaired electrically so now comes the mechanical repair. It has 2 good volts per div knobs but the silkscreend values have

Hello All, New member here. I have a Type 1L10 Spectrum Analyzer plug-in that I've owned for several years. It's nice and clean, however the previous owner removed some parts for some reason. It was
