Tektronix developed the TDS3000 series under the code name Raptor and started building it in 1998, a light scope that could run on a battery. The TDS3054B is the 500 MHz, four-channel model of the B generation. It samples at 5 GS/s and captures up to 3,600 waveforms a second with intensity grading, the digital phosphor display Tek sold it on. The B added a built-in 10BaseT Ethernet port and e*Scope, Tek's browser-based remote control, and kept the floppy drive and Centronics port that the later C swapped for USB. It weighs 3.2 kg on its own and runs about three hours on the optional TDS3BATB lithium-ion pack. Extras plug in as modules, the TDS3GV for GPIB, RS-232 and VGA, and analysis packs like TDS3AAM. Look for one with four P6139A probes and the modules you need.
Options and accessories
Check the listing photos and the rear panel against this list, and ask the seller about anything you can’t see. A missing option or probe should come off the price.
The LCD is lit by a cold cathode lamp, and owners commonly report dim screens as it ages. The floppy drives are old too, and many owners swap in a USB floppy emulator.
New to used bench gear? How to check used test equipment covers self-tests, fuses, the voltage selector and shipping, and what “calibrated” means in a listing.
Buying guide
We'd buy kellyjo_13's TDS3054B at $1,231 delivered, because it's a US dealer's unit titled with TRG and FFT and its photo shows all four channels running. There are at least 58 for sale, nearly all from China resellers asking $714–1,180 delivered here, and most complete ones fall in the $800–1,600 band. The equipwise auction titled as passing SPC and self test sits at $651 delivered but will climb. None of these is titled with the four P6139A probes or a battery, so price those in, and on a China listing ask for a photo of the actual unit with its serial and self-test, since the FUMISO and zecenke watermarks here turn up across many sellers. Skip 2465b's $2,770 unit titled very low 429 hours, which shares its photo with the same seller's 10K-hour listing.
$651.30est. delivered
Titled as passing SPC and self test, from a US seller, at $550 with no bids, or $651 delivered at the current price. It will climb, and we'd stop near $1,000 delivered, just under the $1,074 median, since no probes are titled.
