content: Can you pop the lid and show us whats it's like inside.I scrounged a 50MHz Hitachi junker, but when opened, it resembled a cheap color television.The Hitachi looked nice on the outside but the build was disappointingly mundane although adequate for the spec.For anyone interested, the PM3065 SM can be found here.http://elektrotanya.com/philips_pm3065_pm3067_oscilloscope_sm.pdf/download.html

content: yay. that was me second scope i bought. ( Hameg 603 was my first )these beasts are different from classic scopes. they are a full analog machine. even when you turn the digital on....the digital uses a CCD ( no not the optical sensor but a charge coupled device, although the optical thing is also a chrage coupled device ). the ccd is a chain of capacitors that get analog charge for a given time period. a multiplexer cycles through the cap pool. so there is NO A/D or D/A. to 'replay' the image they simply send the CCD output back to the tube.there is a slow A/D that can sample the CCd output so you can do cursor measurements on it.they use a real scope tube with two beam guns. ( like the good old dual beam scopes ) in analog mode this is a true two beam scope. in 'digital mode' they use the first beam to project the ccd outputs alternately and use the second beam to write text and cursors.it is all under control of a motorola 68000 and a big fat asic.very clever machines.-edit- now that i think of it : the scope above looks like it does not have gthe digital options. in that case its a single beam tube with alt and chop i'm afraid..

content: philips scopes have always been good quality . only prolbem is they are full of those dreaded 0Q chips .... those are chips specifically made for these products and pure unobtainium.

content: Found an operating manual for the PM3055, it covers the functionality of the higher numbered models (excepting the smart cursors found in the 3070). Might help others get familiar with general layout and testing.http://ahars.com.au/documents/Philips%20PM3055%20Operating%20Manual.pdf

content: Just scored one of these babies (PM 3070/74)(100 MHz) and was searching for documentation, particularly an Operating manual, the SM is easy to find. The post above is to a dead linkbut I found this Philips basics pdf that shows the operation of this range of models.Sorry nothing in detail, but enough to get one started.http://www.ee.ryerson.ca/guide/instrument-manuals/Phillips_ScopeBasics.pdfAnybody knows of an active free OM link, I'd be grateful.For those that are interested ...... a sales brochure.http://www.test-italy.com/Specifiche%20strumenti/PHILIPS/PHILIPS%20PM%203055/PM%203055.pdf@ ShockYou might like to edit the thread name to this model/range of Philips scopes.
