Tektronix made a number of oscilloscopes like you describe including some interesting hybrids. Phillips made some oscilloscopes contemporary to the Tektronix 2232 series but supporting 4

That would be the Tektronix 7D20 (as a combined timebase/dual channel scope) which was intended to run at least in the 760x series. and I'd like to have one, but that's still out there,

Look at the Tek 468 scope. It had a digital backpack, capable of about 10 Mhz bandwidth. The processor was (IIRC) and 8051 style, with limited memory, etc. The basic scope was a 465, a 100 Mhz

Hi all. I have a mint HP 8447D 0.1-1300MHz amplifier for sale. It is in full working condition and in good shape. It is excess to my needs and so selling it away. Asking $250 plus

HP 1980B has a digital sampler board used to store a waveform. It has a whole 501 points of resolution. This is an Analog scope with Digital controls. Very nice " AUTO-SCOPE " for it's age.

Tom, you may have a valid point. I'll have to look at the schematics. I think it's a bit safer however to use a battery substitution voltage then to have the entire instrument up and running. Heaven

Christian, I have an 8970B, SN 2947Axxxxx, OPT H18, and when I enter '99.9 Special Function', I get '08844' in the left hand display. When I enter '47.1 Special Function', I get no errors.

The 7854 does take some learning, especially if you want to use the keyboard functions. BTW, a 7B53A is not the correct PI as a sweep. It is a sweep for something like a 7603 or other 100 MHz

Steve, Thanks for the data. Mine is also 2703A prefix with REV?:6,0 and CALNUM?:98. Not a multiple of 34. Would be interesting to see what the CALNUM increments by after an Agilent CAL. I,

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
