Hi, That is correct. Two red wires are connected together. I modified all my 222,222a, 222ps and 224 (cca 6 scopes): - used 7x 2700mAh NiMh cells, - put thermal switch in serial - put external

Hi group, i have harvested a TDS540 which shows aquisition board error during self test. I could get a TDS540A for low quote with a smashed CRT and i think about to swap the aqui-board if

Sorry about the repeat of my original post below. I was trying to write an update and one of my cats walked over my PC keyboard. Anyway, measured the PSU voltages and all except the 130V are high by

Hi Michael, Another company selling the idential stuff is Vector Electronic (http://www.vectorelect.com/)s. It is quite commonly available here in the US from at least these three parts

It is there to protect the ICs on the main board from being crushed if you hit the bottom of the case (like when you slide it off a bench). The seam of the case extended too far into the interior if

Sorry for the long post – detailed troubleshooting info follows: Here is the latest in my attempts to repair the HV section in my SC-504 Scope. The circuit is drawing excess current from the

Just an update on this. I checked the PSU voltages at the test points and all, except the 130V line, are high by about 10% which is pre-regulator voltage. I did a swap of equipment with another member

Both red wires are connected to the positive battery terminal. It allows the battery connector to be mated either way roubnd and still work without letting the smoke out !! John Barnes

Thank you kindly, Geoff and John. I feel rather stupid now. Clearly haven't been using the right search terms. :-) Michael

Not sure what your design is but there are many 0.1" boards.?If you are?more specific about what you want to accomplish, we might be able to help.??? ? Maranne for atSpeed www.atSpeed.net

Dear group, Please pardon an off topic question; it's the only place I can think of asking since many of you are designers and may have worked with this. I've been searching for Vero boards for

I think you should leave alone the 7Axx inputs, they are perfectly fine as they are ;-) (I say this because this is not like the 222 probe issue where the probe is non-standard and hard to get, Tek

You could also remove the protection diode and other components paralleling the 1 meg input resistor to further reduce the capacitance, but you might run into inadequate adjustment range for the

Err, what exactly does the calibration of input capacitance do then? If you have a 'scope with input impedance of say 20pF in parallel with 1Meg, putting a parallel resistor capacitor of 1Meg/20pF in

You cannot "change" the input capacitance of any Tek vertical input. It is what it is. Use a Tek probe. HankC, Boston
