My 585 manual says “with 485 EMI mod option 4 meets mil 1-618D req: power line conducted, 150khz -25mhz; radiated , 150khz-GHz [sic]. Don’t know what the mod is though. If someone knows, please

Ah, the HP 54503A must be similar to the 400 MHz 54504A DSO that we have unused in the storage area at work. Came from a power supply vendor who went out of business, but we have more modern Tek

The 2440 can be a real craps shoot. I had one on the shelf for many years that was failing self tests so bad that it would never boot to even crippled functionality. One of the failures, as I recall,

I just got a 19.5 volt 45 watt HP supply today. The connector is a large 3 contact coaxial, Positive Center pin, Negative Outside Sleve and Voltage control on the Inside Sleeve. Voltage measured 13.4

The outer diameter. I've seen 6, 9 and 12 volt adaptors where the plugs will not go into something with the "wrong" voltage requirement. The older ones seem to standardize on one thing and it's up to

You mean the outer diameter ? It seems the pin is more based on the current. this laptop, I can plug its adapter into a smaller and older laptop, but the for it will not plug into this one because of

Speaking of the 7104 I have a very nice R7103 ( rack mount 3 slot version of 7104) that as Harvey says I no longer wonder why I need it .....I dont!! _*Make an offer*_ , pick up ONLY in Tampa FL area.

I have a 7104. I use it only when I need the MCP or the 1 GHZ bandwidth. That requires either a direct coax input or a 1 GHz probe (and, for that matter, something where the bandwidth is needed).

The 1982 catalog lists Option 04 for the 485 indeed as EMC option -DC manuals@... -- Dave Manuals@... www.ArtekManuals.com

The 2400 series digital are pretty cool. What I’ve dealt with over the years of repairing them is yes the NVRAM batteries can be failed which adds up to replacement recalibrate. . But rebuilding the

I just got a nicely refurbished 485 which lists "opt4" under the SN. I could find no information despite several searches. I was surprised at how little information there was at the w140.com/Tekwiki.

I'd say that could be likely.? I bought a 2440 at a flea market for more, and it was stone dead when I got it home.? With the help of people on this list, I got it running.? The archives should

I think I'm going to pass it up. I need to start being selective on my scope choices. I think my next scope will be one I really want. Which is a 2467 or 7104 with a MCP CRT.

Just remembered something - there is also a safety circuit designed to stop powering up in the case of short for any of DC voltages rails - so theoretically if there is a short at some other board the

Personally I would offer less - in addition to power supply caps and possible damage to the traces under the caps there is a possibility that the NVRAMs will have to be changed ( dead batteries ) .

Gentlemen, The vast majority of comments on this topic are completely lacking any relevance to the TekScopes. Please stop wasting our bandwidth. Thank you, Dennis Tillman W7PF

I'm looking at a 2440 that won't power on for $85. Worth it or not? What is the likelihood of just power supply issues and no IC problems? Thanks fellas

I had a boss who made that necessary. I go in the office, tell him what a job needs, we got it, callem am tell me if I should do it. He gets on the phone and I hear "OK, we'll be there with it around

Everyone knows that Scotty always pads the estimated time by a factor of 3.5 to 1. The Outer Limits episode with the monkey working in something was on Comet TV last night, at midnight. Michael A.

Well, yeah- but if he had ever failed to get the engines working again at one of those critical junctures... -Dave To: [email protected] Sent: Wednesday, July 18, 2018 11:08 PM Subject: Re:
