Does anyone have service info for this cute X-Y plugin scope? A schematic would be most helpful. Thanks George Plhak

That seems to be the way to destroy both ;=) In my 547s, some handle bar screws are PZ2, and some are PH2. You feel immediately that the wrong combination of bit and head is wrong indeed. Like Fred

A few years ago I purchased a "Security Bit Set" from the Cheap Chinese Junk Store AKA Harbor Freight, it has a number of Posi drive bits in it. Also HP used the Posi Drives in a lot of their

I bought posidrive bits at http://www.mcfeelys.com/pozidrive-bit . The bits seem to be good quality, do not round off easily. I used a posidrive bit on a Philips head screw where I could not get any

Just looked at some Teks, my 547 and scope mobile had philips, exceot the frontpanel seems to have some torque. The 453 had Philipd but the fan is nounted With pozidriv, the 7000 serie looked all

To be specific. I think you mean, hardware store in the USA. There is a wild outside the US, we use strange things like metric instead of Inch, Celcius instead of Fahrenheit ect. And so there are many

Here in Europe pozidrive is the standard for most mechanical screws. Mechanics screwdriver sets typically come with pozidrive, electricians sets typically come with philips, so we can easily get both

I am getting a Test 04 Fail 01 error on a 2445A scope and I have been through the cal proceedure four times. I keep getting the error but when I exit out of the self test, every thing works fine.

Tek used Pozi screws in all of their equipment as far back as the late 1960s. At casual glance they look like Phillips Head screws with four little marks at 45 degree angles to the slots. There is an

There are adjustments for the horizontal gain (for x1 and x10) and position and it is done in the Cal-01 process. The vertical adjustments are done in cal-02. A good read of the calibration section

Thanks for the responce. This id the scope I am waiting for the new U400 to arrive to fis the vertical compression issue. In the meantime I have been testing other functions. The vertical measurement

Re: 7B92 No Auto trigger

Hi Albert, I had a few minutes to do some probing, and it looks like CR364 is being triggered on the leading (falling) edge of the square wave from the collector of Q376 which is fed by the comparator

See '465 with DS' photos under Photos folder.

The adjustment of R1501 is done in the Cal-06 step, vertical transient response. It provides a termination for the vertical deflection plates. Cal-06 is one of the hardest to do in my opinion. If your

Those types of receivers are examples of the first type I discussed and are the most common. Both types can achieve 1 part in 10^12 accuracy but it takes more effort with the non-Thunderbolt type. You

Hi, Curious what this does and what is the adjustment procedure. Gave a quick look through the service manual in the CRT adjustemnt section and it is not listed. Thanks, B

Thanks for all of the very helpful replies! What about a non-Thunderbolt GPS receiver that only outputs a 1 pps signal and has no provision for a 10 MHz output? For example, a receiver that has

I asked about this not long ago on the time-nuts@... mailing list. Most receivers have a fixed frequency oscillator driving the numerically control oscillators so the 1pps output has significant
