TERMS AND CONDITIONS: We do not warranty consumables such as batteries. Lamps or software. EBAY requires sellers put in a CONDITION CODE on all listings. EBAY did NOT include a CODE that describes our products. Whereas. 95% of our USED items work for our customers, many we are unable to test(or do not know how to test) and therefore have a small chance of not working as intended.

We are surplus equipment dealers and do not have the ability or knowledge to test equipment for functionality beyond plugging it in and describing what we observe. Buyer is responsible for calibrations. Repairs, or upgrades if needed. 2. We have done our best to provide information that we found on websites.

Tektronix 500 MHz 4-Channel Digital Oscilloscope FOR PARTS. AS IS. Does not completely boot up. Screen display is dim. When powered on. The oscilloscope cycles through the self test and begins to boot up(you can hear the relays clicking on the attenuator assembly) But toward the end of the boot up process, the display screen freezes with a line at the top(see photo) and the 7-segment display on the processor board alternately flashes the top and bottom left side segments as it would during a normal boot(see picture) Using the Tektronix Service manual. The voltages inside have been checked and are in spec. The capacitors on the aquisition and processor boards have been replaced and the boards cleaned, but the problem remains. I suspect that the battery in the NVRAM is low and the checksum is bad. The Tektronix service manuals offer no help ... morefor how to fix this problem other than"replace the processor board" Also. The line on the screen display is very dim and probably needs to be replaced(see picture) RcmdId ViewItemDescV4,RlogId p4%60bo7%60jtb9%3Fuk.rp*a4%601gc%3E-14545485c77-0x113-
Working perfectly. Guaranteed by 6 months right of return. And 1 year repair/exchange warranty while I still have a backup unit. Note: TDS 644A is basically the faster sampling rate(2GS/s) version of TDS 544A(1GS/s) Passes all self-tests(including Signal Path Compensation. SPC) Comes with these options: Option 13: RS-232/Centronics Hardcopy Interface With this option. Tektronix ships the oscilloscope equipped with a RS-232 and a Centronics interface that can be used to obtain hardcopies of the oscilloscope screen. Option 1F: File System(Floppy) With this option. Tektronix ships the digitizing oscilloscope with a floppy disk drive and a variety of features for managing the floppy disk. With the file system you can save and recall setups, waveforms, and hardcopies on a floppy disk. Option 2F: Advanced DSP Math With this option. The oscilloscope ... morecan compute and display three advanced math waveforms: integral of a waveform, differential of a waveform, and an FFT(Fast Fourier Transform, Spectrum Analyzer) of a waveform. This has built-in GPIB interface for communication to computer. This unit has a color screen and connects to color monitors through VGA port. TDS 400. 500, 600 often have electrolytic capacitors leaked at this age. Regardless of whether they function well and pass the tests. They must be recapped and washed or it's a ticking timebomb. Once you see Acq++ fail. Chances are the electrolyte has eaten into the board traces and it's gone for good. All SMD electrolytic capacitors on Acq and main board and washed. Recapped and rewashed throughly. You can return in 6 months for ANY REASON as long as you pay for shipping both ways. If it fails with a year of purchase. I can have it repaired or replace it for free and will pay for all associated shipping costs. If I cannot fix it, I'll gladly refund.
