Vp-7723a user manual

More options. I have seen failed ram, eproms and CPU's but I'm not sure what you mean by leakage from memory cell. Perhaps you meant leakage from a capacitor, or a backup battery? The manual should have that info. Probably from the memory backup battery A large battery in the center of the unit. I might part with my if you cant fix yours. There is also an A for sale on ebay at this time. Now there is one for sale on which it says DC-range defective.

Wonder if that is easy to fix I would really need a audio analyzer, currently I use a bit FFT. It will show all harmonics, but range is max 90dB. Click to expand Thanks for the tips. I think Audio Rightmark is not real-time? Are the other two free? Problem is that I do not really have space for a computer in my lab, I will get a bigger table soon though.

Then I will have all instruments on a shelf above the table. A laptop will likely not fit on a shelf though, keyboard will be too high. Problem with computer based systems is that they need a display, attenuator, printer and some sort of input device like mouse or keyboard. Also frequency range is limited.

When operating the attenuation, the display comes back on, then it goes away once I stop. I looked at the user manual, and if this is the intended behavior of the unit or there is a way to make it stay either on or off, but I sure missed reading that part.. I am inclined to believe that there is a faulty component in the unit that causes this to happen and wanted to know if anyone here is familiar with this audio analyzer or has any other suggestions.

Your help would be greatly appreciated! Armadillo Super Contributor Posts: Country:. Panasonic VPA is a audio analyser.
