Philips/Fluke PM339X Combiscope series are the true analog scope with proper digitiser, very easy to use and it performs well. The catch is it may not be very reliable. According to my experience,

Steve, the one I'm getting appears to be start with 3114A for the serial number with STD (Standard) for options. I assume the serial number is above the bar code and under the model number. I've

Yes. The Tek DPO, based on the 7704 (or possibly the 7704A) was the first AFAIK. Then there was the magnificent 7854. IMO, this is the BEST lab 'scope ever made. It is still my 'scope of

Bryce, Several Tektronix scopes work that way. The portable 2232, 2211, and several others have a STORE/NON-STORE switch that lets you look at the same signal in either mode. The Tek 7854

I'm not sure how to get a ROM dump out of the unit, but mine is version 2844. Help me with capturing the data and I'll happily give you a copy. 73 Dave K2DH

Haha, I guess not as it sold really quickly! Peter

It would be interesting to see if a newer rev is out there. My 3457A is s.n. prefix 2703, with rev 6,0 and option 0, CALNUM=34. I wonder if that's a default number for anything less than a full cal at

Did HP (or Tek, or anyone for that matter) make any oscilloscopes that were basically analog scopes, but with the ability to digitize what is seen on the display (at some lesser resolution than what

Almost two years ago I posted the above message, but till now did not get suitable answer. Maybe someone could read a recent ROM and post it? Please note K04BB's site only holds 2705 version of the

At the risk of shameless self-promotion, I've placed a GPIB-to-USB adapter on the E-place for sale/auction. I hope I've chosen a reasonable price range. If you want to have a look, it's item

Todd, the battery is already on my list of to do items. The security seal on the meter I've got on the way appears to have not been broken. I assume this is from the last cal back in 98. The fact that

Martin, Well that is the information I was looking for! Thank you, however that is not what I expected. That was option "2" for me. To me it seemed more logical to provide a 600 ohm load to the 600

It seems that for about $11 it would be worth buying some and experimenting with it. Dave

Dave, Thanks for pointing that out. Dave

Another important consideration will be the onboard battery BT501. See if you can determine its age. Also, according to my manual (dated Feb 1988 ed 3) on page 6-26, along with the list

Which nylon clutch parts? The attenuator gears on mine, that slide to engage, are brass, with what appears to be a standard 45degree tooth face. The only nylon parts are the switch finger cam and

Hello All, my first post :-) I have been searching the group history for any information about a possible source for the Nylon Clutch mechanism that is part of the input attenuator/reference level

Thanks Joe. Gives me a bit of piece of mind. I may have overlooked your details in the post. So I assume the self test OK message pretty much rules out failures I need to worry about ? My apologizes
