Put the scope in X-Y mode, with no input signal, and measure each vertical deflection output to ground. They should be about the same voltage. If one is at zero, or the supply voltage, that driver is

those of you that have come to one of our previous stuff day events know that there is a great mix of free and cheap electronic "stuff" for everybody to snorkel through. it is a true BYOB (bring your

I have had another snoop around with my multi-meter and I find that test-points 4 and 7 on channel 1 both show +5.7V, the equivalent ones on channel 2 show +3.37V (TP 11) and +7.31V (TP 14). What does

Dual amplifier in left and right vertical (set to chop or alternate) and dual timebase (such as a 7B92A) in each horizontal compartment. Select vertical mode beam 1 right, beam 2 left. Set horizontal

Beamfinder is working properly. When pressed, the display compresses to a single position on the x-axis, but the amplitude remains. Here is a helpful hint...I pulled (disconnected) the upper and lower

Hi all?I for one have more scopes than i can or will ever use , but for some strange reason i keep getting them . For me it just fixing them that i enjoy and once fixed it goes in the pile that i

How?

Most men will know that is a question best not asked. My scopes: 2232, 2246 2445, 2465 7704, 7844, 7854, 7904 TDS210

John: I received the viewing hood today. Looks great. Thank you. I will send a check off to you today December 8 2018. Gary

Hi Bob??Thanks for your reply that you sent to me with pictures I would like to ask you if you could possibly let me know the gauge of the wires there and the possible length of the cord coming from

I'd say you've found the best source already. A lot of us use our scopes on the bench, and take the probe pouches off so we can stack things on top of the scope. So, post your requirements here.

My experience with failing capacitor is the strong smell of raw fish. Sometimes I can smell it as soon as the unit arrives or definitely during case removal. I don’t think I’ve noticed a

Mine actually has 3 in that position - I had assumed that was their purpose - thanks for the warning, though. Dave

Yes, that may work with the application of some self-adhesive Velcro. Dave

Thanks Dave. I suspected that a bad NVRAM will let the scope at least get as far as the DPO splash screen. I guess I have a deeper problem. Can anybody else suggest where I should look?

(No, he didn’t. That’s what you get for replying after just skimming a thread. Promise to better myself.) Grü?e, Carsten

Old devices often have a characteristic smell, e.g., from the dust that is being cooked inside the device. Some of this smell unfortunately stems from leaking capacitors. Is there a guide somewhere
