This is a nice scope in good operating condition. It is a digital sampling oscilloscope with 1GHz rate and equivalent time sampling for higher frequency repetitive waveforms. The Tek 544A comes from the factory with all the options popular for the time. Advanced triggering modes, extended acquisition memory, floppy drive, and advance waveform math(FFT, differentiation and integration) When it came to me it had three issues common to the vintage- the standby regulator didn't function, the CRT was not operating, and the floppy drive had disk errors. I made the repairs and swapped out the original Tek CRT with color"shutter" with a"DIY" LCD from a donor scope. Generally, when I repair scopes of this vintage I also"recap" the surface-mount electrolytic caps on the processor, acquisition, and display boards. But ... morein this case I found the three boards were nice and clean with bright, pristine solder connections throughout. This indicates low total usage. In my experience it is better to leave things undisturbed unless there is a good reason. I ran through the operation modes, including GPIB(re-zeroed the error log) and the floppy disk hard copy.Several minor issues keep this scope from perfection. It has the usual dings and sticker residue(I cleaned some of the worst with IPA) The rear display connector(VGA 640 x 480 color) has been repurposed to drive the LCD. The LCD flashes"No Cable Connected" for a few seconds after turn on until the scope starts up the VGA. The AUTOSET button(handy in any DSO) has to be pressed quite hard, but works. The calibration is not current, in case that matters in your work. This scope should give you a long and very useful lifetime. You'll find the 544A far superior to those newer"lunchbox" scopes, especially in some of the advanced sampling modes. The LCD is set up for best contrast when viewed from above, so it will have nice contrast and viewing angles on the bench, but not so much if placed up above the operator.
Normally listed for $1600. Briefly lowered to $1499 from now Feb/2013 until May/2013 as tax season is coming. Working perfectly. Guaranteed by 6 months right of return. And 1 year repair/exchange warranty I still have a backup unit. 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(Standard on TDS 524A& TDS 544A) 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 1M: 50.000 ... morePoint Record Length This option provides a maximum record length of 50.000 points per acquisition(50,000/channel) and nonvolatile RAM storage of up to four 50,000 point records. Option 2F: Advanced DSP Math With this option. The oscilloscope can 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.
