This reminds me of my open hardware project electroporator. It's a pulse generator, (for low power pulses), with an ADC capturing each "shot". There's no need for a knob twister pulse generator like

Arbitrary Waveform Generators run a repeating digital to analogue conversion on a series of numbers, so a waveform library is sets of data corresponding to various patterns such as sine waves, saw

Why? The 576 has a "ZERO" and "CAL" button, placing the dot in the lower-left or upper-right corner of the graticule. You just have to align the amplification and offset of the scope to match. Of

Since you are planning to test vacuum tubes, David, look up Dennis Tillman's excellent write-up on how to mate a curve tracer with a tube tester.? If you haven't already.Jim Ford?Sent from my

I figured, Roman.? But it's good to get the information out there for those who haven't been designing boards for decades.JimSent from my T-Mobile 4G LTE Device

In the days of old storage on a 576 could be done with a grease pencil on the plastic or cameria system. There is someone who supposedly has a trace saver out on E-bay but they want $3500. And there

I'm interested in hearing what can be done for this problem. I have five 7000 instruments. My most recent aquisition has the outside cover for the horizontal bay refusing to stay snapped in place. The

A few days ago, I moved a side cover from a donor instrument to my extender (which had one cover missing). I found it a delicate process. The plastic seemed to be dangerously brittle; but, I got it

Jim, Yes, brain f**t, of course solder mask. Roman

Has anyone encountered a sweep discrepancy with the alternate mode on a 547? I have calibrated the caps and resistors in both time-bases to match each other. When using the A sweep by itself the trace

After years of wanting one, I've finally bought a 576 which I believe is currently sitting in customs 20 minutes from my place. Like quite a few people out there I'm mainly planning to use this for

Hi, It's been long time since I posted anything but hoping someone can help. Does anyone know if a 492 ( not an A,B,P etc) can be retro fitted with the 1st oscillator phase lock and pre-selector

Anyone???

I know this is 5 years old but I had the exact! same issue as yourself and found the problem. Let me know if you want the details. :)

I haven't moved any of them in about 3 years, so I don't recall, but I don't recall it being difficult.? I know I've removed and reinstalled cracked ones, so it's not THAT hard. -Dave

got the manual but had to go for an operation on my foot last wed,seems i wont be able to put weght on said foot for another 7 weeks,so cant look at scope untl then.

It doesn't surprise me. Just remember that information is sometimes defined as the logarithm of the probability: or, In = log (prob(x) ), where In is the numerical value of the information. The devil

As I approach 90 ( I'm 88 ) 7K scopes are a lot heavier that they used to be also. >

If, IF, I do find some replacements, I think I read where there's a specific way to clip them into place. I see where one edge is a bit wider than the other and I _think_ that edge goes towards the
