While I am sure there are many tips that others have, I found a thin hot soldering iron pressed into the iron screw socket head will sometimes add enough heat(expansion) to get things going. I have

I'm sure you'll get a lot of great suggestions. Until then, here are my bodges. One is to use a sacrificial metric wrench that fits tightly, perhaps with a little tapping to encourage insertion. A

The "Re: [TekScopes] NEW TOPIC: Outstanding Rockland Instruments 7000 Plugin; WAS: Slightly OT- Wavetek 7530B?" post got me thinking about? "rom rot" and wondering if anyone has archived the eprom

Correction, the cable used for BW test, GenRad type 874 connectors, 75" RG214/U (Not RG/6u 75 Ohm !) Jon

They are typically 1/20" or 0.050" keys. Sometimes it's Bristol drive but if someone forced a hex key in there it's probably not a Bristol drive anymore. Unfortunately I have found no way to extract a

Need to remove the horizontal control knob on my 576 so I can remove the board to get at the display selector board. One of the grubscrews undoes easily enough, but the other appears to have its hex

Hello all just checked the Yokogawa DL7440, with Leo B 40 ps BNC pulser, get 570 pS RT, OS ~ 14.5% Using HP RG gen 8640B , Gen Rad RG/6U cable and 20 db atten, getting 3 db at 607 MHz. 0.35/Tr gives

Carbon comps with metal end caps have bulges, too, so you can't always tell by sight. Crack yours open to be sure (but I'm pretty sure it's a CC). Cheers Tom Sent from an iThing, so please forgive the

Yes. That is a good recommendation. However, I don't know how to follow it. If one parses effects into: "short term" exor "long term" OR "acute" exor "chronic"...(to suggest some combination of

Colin,- Ooooh! Thanks for the part number. I have a pair of used ones on the way from Q-service now. Lord knows how long that will take with the current state of our post office... <sigh> I agree, it

I think you might be able to get one of these 3-conductor BNC sockets from Qservice or Sphere. It is described in the Service Manual as "connector, Rcpt,: BNC, Male, 3-contact", the Tek p/n is

Ed and Raymnond: HAve several Yokogawa scopes, with 500 MHz BW will try out and post images. The transient response on analog scopes can be tweaked for best risetime but sime overshoot, and usually

Hi Dennis, This job is indeed very busy and complex. The temperature, ice and wind conditions at 3600m altitude forced me to develop a lot of specific equipment for the task. The problem is not only

Hi Raymond, I meant to look at effective bits as a general view on all DSOs. I don't know what the detailed differences are among the TDS scopes. I actually find it quite confusing with all the

Said switch is on the front panel of the 7104 - turn the readout pot fully clockwise into the detent at the end (PULSED position). To quote page 2-10 of the manual: The READOUT control determines the

I have a couple of TDS3054Bs and have had one TDS3064A, and have done rise time and -3dB measurements on them. Just as others have mentioned, I saw around 700pS rise times and 600MHz -3dB points - on

Also back in the 1960’s - > early 2000’s most (but not all) HP/Agilent ETE was very conservatively spec’d so that most of the ETE would easily pass spec (if not broken). It was common to see ETE

Jim, I was one of those HP/Agilent field cal guys doing the MTE, never did it for Raytheon, but did it for 100’s of other customers. We verified that every instrument made published specs - no

Hi Mark, Very nice to see you here! Your review article on sampling scopes is a true classic. I blame and thank you for the happy hours I've spent trying to chase down and then read, all the
