So is there a bottom line here?  I have ordered replacement NVRAM modules but now am leery of installing them, as I may lose calibration, which seems to be good even though the batteries are

Quite likely. True for the operational settings, not true for the Adjustment (chapter 5) data that is stored in the "store..." menus during Adjustment. Here I disagree. If this were true, what purpose

Hello friends, The 7854 that I recently bought, after some minutes of operation started emitting a whistle, a burst, some smoke from the rear ad an awful burning smell... "as usual!" I thought,

Dear Manuel, I may be able to do it, but am traveling away from the lab for a while. If you can wait till early or mid December remind me with private message and I will check my inventory. How many

I guess the following is relevant: The samplers as used in the 7S11 need much sharper/shorter strobe pulses and a special physical layout to achieve the much higher bandwidth and the battery circuits

Hi, No, there is no other writable store in the instrument what i know about, and there doesn't seem to be any on the schematics. I think what the SM says here is when you press the button, it

Hi, I scored a nice AWG 2021, in a rackmont setup. I had to do some metal bending, as it was dropped at one time, but it is working now nicely and has all the nice options of 2nd channel and the FFT

Thanks for your answer Raymond, I have studied 7S11 and 7S14 vertical blocs. Question is why 7S11 works without cells, and 7s14 need it. And if is possible to use 7s14 with the same scheme. 7s11

Hello, maybe this video helps you - soldering SMD leds, down to 0603 is doable. Just be careful not to "crush" the LED with the pincer when it is

Jamie, Same here! I was trying to figure out a way to pick this up or make arrangements. I just cannot make it happen. This is a treasure trove of great stuff! -- Michael Lynch Dardanelle, AR

You have to read the doc of the 7S11 and the sampling plugins as well. Note that the 7S14 is a complete horizontal and vertical sampling unit and the 7S11 is just a vertical plugin for the 7000

It makes me so sad I but I simply can't afford to travel and buy this beautiful gem right now. I thought someone here might be interested: https://www.facebook.com/marketplace/item/472746093502260/

Dan, You are correct. The 535 came from Stan Griffiths at the Vintage Tek museum in trade for a 570 they had. He said he tried to explain that Tektronix was a post war company and that any Tek scope

is the 453a-1 transfo the same,ie the one in the hv compartment?,as mine is stuffed!,cheers Paul m3-vuv.

Take a look at http://w140.com/tekwiki/wiki/7S14/Repairs and the 7S14 circuit diagram.

Congratulations! It will be the first of many. -Chuck Harris michele.trozzi@... wrote:

The cell voltage was 2.74 V, now it is 3.23 V. I just successfully replaced. I followed your advice, using a second cell soldered to pins 4-8 of DS1210. My wife saw me during the work and told me:

What is the cell's voltage now? -Chuck Harris michele.trozzi@... wrote:

Hi All, A long time ago someone said it is possible to lubricate the Oilite Bearing if you place the motor in a vertical position and allow oil to seep into the shaft area. I have not been into a

Reading the manual I have understood that after data loss in the NVRAM, you can do a simple re-calibration using the internal calibrator. This can allow to make just qualitative measures. All
