More, Ron - I checked the 1975 catalog. It lists the P6056 as X10 and P6057 as X100, both working into 50 Ohm scope input. There is a super probe out there, a FET probe, P6201 that goes to 900 megaHz

Ron, The 7A19 is a very wideband instrument. An input impedance of 1 megohm and 20 or 25 pf would cause it to roll off to quickly, limiting its bandwidth. You can use a probe designed to work with 50

I have a 7A19 plugin which has an input impedance of 50 ohms. Why was this input impedance selected ??.(most scopes are 1M ohm). What happens if you use a high impedance probe with this plug in?? What

Hi All, Thanks for letting me join TekScopes. As I look around I see some familiar faces from other groups. Hello everyone! I have a problem with a recent acquisition from the big auction. It is a TeK

hello, group! oscilloscope: tek 5304 display unit: D40 horizontal unit: 5B40 vertical units: 5A38 (i have two) settings on the horiz unit are 0.1 sec/div and auto trig on. everything else is off.

I have an ugly but original manual for the Type 549 Storage Oscilloscope that I will send for $5.00 to the first person who tells me they want it. The $5 includes shipping by media mail. It is ugly

Hi, Michael: The aluminum chassis in Tek scopes has been Alodized or Anodized (I can't remember which process is used). This process cleans the surface and hardens it. I'm no chemist, but I think part

Hi, Dave: The vertical signal connections are where the coax is used, plus two more for the "flipped version (580). Before the 580, they were not coax. For the rest of the connections, you can check

Hi Michel, The only part that I know of in that scope that can be damaged by water is the power transformer and then usually only if you submerge it in water or use water with a lot of metal ions in

Hi Michael, The black capacitors I am talking about are located in the -150, +100, +225, +350, and +500 power supplies and not in the high voltage area. You should be able to remove and replace these

Well, I have just taken a cover off my 012-038 500-series flexible extender, and the cable is just 16-core plain wire. No coaxes in there at all. BUT it is a good job I took the cover off, since there

I've searched the archives a few times, but I haven't found a really good description of the 500 series scope extension cable. Based on what I did find (and looking at my MFs and PIs), the 93 ohm coax

I have a fully functional SC504--except for the channel 2 attenuator. The SC504 attenuator has a cam that causes individual contacts to be pushed into contact with plugin boards containing the

its like a meter , reference level= full scale. scopes are volts per division so are chart and xy recorders division= 1 inch or 1cm on most chart or xy recorders
