Obviously if that is the case you don't have enough Tek gear ;-) ST <TekScopes@...> wrote:

Hi All... I have several pieces of Fluke equipment. I have tried to find a Fluke Group, with no avail. Can anyone point me to one? Also note: I have several pieces of Tek gear as well and all of

Yes, they do. Actually, it's the 1813,1823,1833,1843 trigger chips (1813, not 1812). Yes, about 0.25" square, not larger. When I put my 50 W temp-controlled soldering iron onto one, the top of the

Hi RaY; Thx for those. So the bottom solder pad/via blocks represent the PCB cooling for the 1812,1823,1833,1843 trigger chips? Can you give an idea of the dimensions of those solder via/blocks? I'm

I created a photo album entitled "TDS694C Trigger Problem". I put in 3 photos that I took a while ago, showing the trigger chip area on the bottom of the acquisition board with the four pads ("solder"

Hi to All, Just uploaded a picture of this 670-3277-03 Board into the Photo Section. Greetings, Egge Siert

Hi to All, Just out of curiosity I acquired recently for little a nice good working 7B92A with a high SN (B101040). This one has allready the Clear/Transparent Rear Panel of the later production

I think David has actually outlined the reason for using the aliased display for setting the CCD clock timing. If you use the real time display in repeat mode it requires a significant fraction of a

The regulator circuit is made up of Q4228 and Q4233. They increase drive to Q4008 and Q14009 until the current through R4127D from the -2450 balances the current through R4127C from the +55.6

The problem with vertical positioning and lack of full signal traces on the screen of my 7D20 was tracked down to a bad inductor L480 on the +15V supply line to generate reference voltage for the 2

I do not think that schematic is correct where it shows a direct connection between the intensity potentiometers and the non-inverting amplifiers or maybe there were two versions of the 2247A. The

The intensity controls work through the processor and do not control intensity directly. Start by bringing up the Service Menu by pressing the top and bottom CRT buttons simultaneously. Then go to

Tried attaching the photos but it won't work. Anyone know how to add attachments? Tried sending email manually using outlook, but still failed. Here are links to the photos in google

My 2247A operates just fine and the display is good (nice and bright), except the front panel pots for A, B, and Readout Intensity have very little effect, if anything at all. The Readout pot will

Also are those IC types TQFP or QFN? what size? QFNs have the thermal pads.

Thx, for any pics. Did u notice any electrolytic/SMD caps inside the system? They could be one cause of oddball probs if they corrode data traces.

Hi- I had triggering problems with all modes. They all use the same trigger chip. As for photos, I don't have any, but if I dissemble the unit again in the coming days, I will take some for you.

well, at least inexpensive progress was made.

Thanks for your replies. Yes, I replaced every electrolytic cap in the oscilloscope and cleaned the Boards with aerosol. Just took out the front panel board again and cleaned it with water, dried
