    Oscilloscope CPU architectures

    Technically, this involves part of a computer, which is the CPU.

    I am curious of what CPU architectures have been used in oscilloscopes.

    As far as I know, LeCroy used Motorola 68000, 68020 and 68030 CPUs in their scopes at one time, and I have seen a number of ARM CPUs being used in newer scopes, and some of them have the x86 (and even the x64) architecture - I've seen Tektronix logic analyzers use Windows (including 95 and 2000) too!

    What other CPU architectures have been used in oscilloscopes (past and present), particularly Hitachi Super H, MIPS, Motorola 68040 and PowerPC?
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

    UPDATE: Tonight, I have found that LeCroy was at least one of the manufacturers who used PowerPC CPUs in some of their scopes, but I am still wondering if the 68040 was used in oscilloscopes.

      UPDATE: During a random search, I found Yokogawa was at least one of the manufacturers who used Hitachi Super H CPUs in their scopes, but now I am wondering wherether MIPS CPUs have been used in oscilloscopes.

        honestly i don't think many people around here care enough to pay any attention, i'm not trying to sound mean but, i don't think anybody cares all that much as long as it works mate. its sort of like "your hardware RAID card has a MIPS processor" most would respond "ok" anyway its 17:00 over there? its 24:00 over here! so night.
        Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

        You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

        Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

          Re: Oscilloscope CPU architectures

          Oscilloscope architecture is fascinating.

          Most modern scopes use a high performance FPGA to capture data and write this data to the LCD panel. Some, like the ones from Agilent and Tek, use an ASIC. Usually the main processor is only responsible for features such as waveform math, FFT, and the user interface, so doesn't need to be particularly powerful. Agilent's new 3000X scope only has a 400MHz ARM processor (running Windows CE...), because most of the heavy lifting is done in their custom ASIC.

              Isay exactly what tom66 said.

              If you go on YouTube, there is a channel called "eevblog"

              There are a numberof digital oscilloscope teardowns on there. Be warned, the videos are sometimes over an hour long xD

                  How not to Damage an Oscilloscope
                  by Tarot Superstars
                  Hello.
                  I have jut got my first analogue oscilloscope. An Isotech 620 20MHz.

                  I want to learn how not to damage it, and I found instructions on the internet obscure.
                  They talk about ground, earth, floating ground, this, that....
                  But they don't actually say anything anything useful so far.

                  I want to know:
                  Don't connect exactly this to exactly there or it blows up.

                  For example, I am tracing a signal from a function generator in an audio amp, or testing for voltages in different parts of a circuit.
                  I want to know what not to connect...

                  Dynamco analogue oscilloscope
                  by Evets
                  I have recently acquired a Dynamco D7100 analogue oscilloscope without a user manual. As this is the first time I have owned or used an oscilloscope I would like to try and find an instruction book. The manufacturers no longer hold any information and a Google search only found one site but when I downloaded a 'service manual' all I got was gobbledegook. Any help would be gratefully appreciated or even pointers to a generic manual where I could learn more.

                  CRT Oscilloscope repair
                  by pavithra_uk
                  I received two GW Insteak GOS-622G 20Mhz Analog CRT oscilloscopes to repair. both have shorted transistors and fried resistors in Y plate drive circuit.

                  since both have same issue, I want to find if this common issue with this scope or any other cause. here I attached schematic of Y output circuit.


                  C2570 Transistor. this is Gigahertz range low power transistor (VCBO-25V, VCEO-12V, 50mA) for use in VHF/UHF range. but, that transistor here in the circuit of 160V supply. both scopes have both this transistor fried.

                  Transistors with heatsink - 2SB648A,...

                  Lenovo S145 -15iwl vcore inductor warm.. looking with oscilloscope there is a spike.
                  by Bartoloni
                  Hi, i have a Lenovo S145 that after 20 seconds shutdown and restart (it's working correctly on thse 20 seconds)
                  everything seems ok, but on Vcore inductor ( this is an i3 with just 1 switching power supply for CPU)

                  there is an output to teh CPU with a spike.. seems that inductor can't handle the input...
                  replaced the capacitor (330) and the inductor (R15) without any change
                  any idea? very thank you!

                  input of the inductor seems as usual... only strange thing is that the upper/lower voltages seems to be 21V (main power line is 19.3) ... but not sure this...
