Used Tektronix TDS2000 Oscilloscopes: TDS2024C, 2024B, 2012 and 2022 Prices in 2026, and What to Check

The short answer

From a US seller on eBay on 7 October 2026, a working Tektronix TDS2012 is a $250 to $400 scope, a four-channel TDS2024 or TDS2024B is $400 to $900, and the TDS2024C that everyone searches for is not for sale from a US seller at all. Zero US listings. The 85 TDS2024C listings you will see at $440 to $700 are China-based drop-shippers, and so are 72 of the 76 TDS2024B listings. Filter by location before you believe a price.

• Two channels, 100 MHz, lowest cost: an original TDS2012 at $250 to $400. Seven US listings, the deepest market in the family, and the same 1 GS/s and 2.5k record as the TDS2012B that sells for $540.
• Four channels, 200 MHz: a TDS2024 at $400 to $725 or a TDS2024B at $600 to $900. The B adds USB and a lifetime warranty you will not get to use. The original has a module slot instead.
• If you do not specifically need Tektronix: a new Rigol DS1054Z at $349 to $369 has 24 million points of memory against 2,500, serial decode and a 7-inch screen. The TDS2000 was a great scope in 2008. Its record length is why it is not one now.

Every number here is a dated sample of asking prices, not a quote. The method is in how our price reports work, and the wider bench-scope market is in the used oscilloscope buyer's guide.

TDS2000, 2000B and 2000C: what changed across three generations

Tektronix sold this body for about twenty years. The original TDS2000 series arrived around 2001 alongside the monochrome TDS1000 series, the B generation followed in 2006, and the C generation in 2011. Tektronix has since discontinued the line and names the TBS2000B as its replacement. The analog front end, the 8-bit converters, the 2.5k-point record and the 5.7-inch screen size barely moved. What changed was the display technology, the connectivity and the warranty.

Two things follow from that table. A TDS2012 from 2003 and a TDS2012C from 2015 capture the same 2,500 points at 100 MHz; the C doubles the sample rate and adds a USB stick, nothing more. And the four-channel 200 MHz models, the 2024, 2024B and 2024C, are the only members of the family with a real price gap between generations, because that is the model the overseas resellers have cornered.

What they cost used vs new

Read the overseas column carefully. The China-based listings carry titles that end in seller tags like "*yiso" and "&lhy", the same few operations under many accounts, and the pillar found the same pattern on 28 September. Their medians are real and some buyers do fine. But a return means shipping a 2 kg scope back across the Pacific at your cost, and import handling fees land on top of the price. For a $600 instrument, the US TDS2024B with free shipping and eBay's return window is the safer buy, and the gap is about $50.

The new-price column tells the other half of the story. Tektronix's cheapest current 100 MHz two-channel scope is $1,378 and its 100 MHz four-channel is $3,430. A used TDS2014B at $400 is 88 percent off a TBS2104B, and the new scope's 5 million points of memory and 9-inch screen are what the discount buys you.

Which one to buy, by job

Audio, power supplies, microcontroller work, education. An original TDS2012 at $250 to $400, or a TDS1012B if you can live with a mono screen for $140 less. You will not use more than 100 MHz, and a USB port matters less than you think when the capture is only 2,500 points long.

Repair bench that needs four channels. A TDS2014B at $385 to $420 is the quiet bargain in this sample. Three US sellers at that price, 100 MHz on four channels, and the same USB ports as the 2024B. If you need 200 MHz, the original TDS2024 at $400 to $725 does it, with a module slot in place of USB.

Anything with serial buses, long captures or a budget under $400. Buy the new Rigol. Seven inches of screen, 24 million points, UART and I2C and SPI decoding, and a warranty that is actually yours. The Tek wins on front-end quality and on being a Tek. It loses everywhere else.

A TDS2024C specifically. Wait for a US listing, or buy a TDS2024B and accept 2 GS/s and 12 measurements instead of 16. Paying $620 to a drop-shipper for a C when a B is $600 with free returns is paying for a letter.

What to check on a used TDS2000

The family is reliable, which is why so many are still around. The faults it does have are visible if you ask.

1. The display, in a photo with the scope on. The LCD is lit by cold-cathode tubes, and they age. A pink or yellow cast, a dim corner, or a screen you can only read in a dark room means the CCFL is on its way out. Repair is an LED backlight retrofit or a panel swap, both fiddly, and one US seller today lists a TDS2024B as "light faded display" at $342 for exactly this reason. Ask for the photo in normal room light.
2. Self test and self calibration. Every TDS2000 runs a self test at power-up and has Do Self Cal under the Utility menu. Ask the seller to run self cal with the probes disconnected and send a photo of the pass screen. A unit that fails self cal has a front-end or converter fault you cannot fix for less than the scope is worth.
3. The calibration label and the About screen. Utility, then System Status, shows the firmware version and model. Compare the model on screen to the one on the bezel and the rear label. A cal sticker from a lab is a bonus, not a requirement; what "out of cal" does and does not mean is in what "out of cal" actually means.
4. Hacked bandwidth on B-series units. Every TDS1000B and TDS2000B runs the same firmware; the model number and calibration constants live in a block at the end of the ROM, and a documented EEVblog project patches that block to turn a TDS1012B into a "TDS2022B". The patched unit reports the new model on screen and runs an auto-calibration on first boot, but its frequency response above the original bandwidth is not flat. If the bezel says 100 MHz and the screen says 200, or the label on the rear has been replaced, treat it as the lower model. On C units the same trick has not been published.
5. A real signal, not just a boot screen. Ask for a photo with the probe on the front-panel Probe Comp terminal, the 1 kHz square wave the scope generates for itself. A clean square wave on each channel confirms the front end, the attenuators and the probe in one shot. Rounded corners on one channel and square ones on another is a channel fault.
6. Every channel, every attenuator range. Vertical sensitivity runs from 2 mV to 5 V per division through relay-switched attenuators. A channel that reads correctly at 1 V/div and garbage at 10 mV/div has a sticky relay or a damaged input. Ask for the Probe Comp signal at three different volts-per-division settings.
7. Buttons and encoders. The rotary encoders for volts, seconds and position skip or jump when the contacts wear, and the rubber menu buttons go hard. Ask whether every knob turns smoothly in both directions and whether Autoset responds first press.
8. USB ports, on B and C units. Plug in a flash drive, save a screenshot, confirm the file. The front USB host port is the one most likely to have been abused. The rear USB device port is what OpenChoice talks to.
9. The module, on original units. An original TDS2000 without a module in the rear slot has no way to move data to a PC except a photograph of the screen. The TDS2CMAX adds GPIB and RS-232; two of the six US TDS2024 listings include one, at $400 and $443, and they are the two cheapest. That is not a coincidence, so do not read a bundled module as a reason to pay more.
10. Probes. A B unit shipped with P2220 switchable probes, a C unit with TPP0101 or TPP0201. Many listings are "scope only". A pair of decent 200 MHz probes is $40 to $80, and a set of four is what turns a $400 four-channel scope into a $500 one.
11. The power supply and fan. The internal supply is a known weak point on heavily used units; a replacement board sells for about $100 on eBay today. A scope that takes several seconds to light up, or restarts under load, is telling you. The fan should spin up immediately and run without a bearing whine.
12. Cosmetic tells about history. Lab scopes have asset tags and calibration stickers and have lived on a bench. Field service scopes have cracked handles, missing feet and dust in the vents. Neither is disqualifying, but the price should match.

The lifetime warranty and why it does not help you

The TDS2000B and TDS2000C datasheets both say "lifetime warranty, limitations apply", and sellers repeat it. Here are the limitations. Tektronix's limited lifetime warranty runs to the original end-user purchaser only and is not transferable. "Lifetime" means five years after Tektronix stops making the product, with a floor of ten years from purchase. If the original buyer sells the scope within three years, the warranty becomes three years from that original purchase date. Probes, accessories, batteries and fuses are excluded, and a claim needs proof of purchase from Tektronix or an authorised distributor showing you are the original buyer.

So for a used TDS2000C bought on eBay in 2026 the warranty is worth nothing, and the "lifetime warranty" in a listing title is worth exactly as much. Price every used TDS as an as-is instrument and value the eBay return window instead.

Should you buy a new TBS1000C or TBS2000B instead?

Tektronix's current entry line is the TBS1000C, two channels at 50 to 200 MHz with a 20k-point record and a 7-inch screen, from about $900 for the 70 MHz TBS1072C to $2,300 for the 200 MHz TBS1202C. The TBS2000B adds four-channel models, 5 million points and a 9-inch screen, at $3,430 for the 100 MHz TBS2104B. Both carry the same limited lifetime warranty, and this time it is yours.

If the job is a professional bench where a Tek is expected and memory matters, the TBS1102C at $1,378 is the honest comparison and it beats any used TDS2000 on everything but price. If the job is a home bench, the Rigol at $349 beats the TBS on price and matches it on most of the rest. The used TDS2000 sits between them: Tek build at Rigol money, with a record length from another decade. Buy it when you want exactly that.

FAQ

Is a used Tektronix TDS2024 still worth buying in 2026?

At $400 to $725 from a US seller for the original, or $600 to $900 for a 2024B, only if you need 200 MHz on four channels and want a Tektronix front end. The 2,500-point record length means you cannot zoom into a long capture and there is no serial decode. A new Rigol DS1054Z at about $350 does more for less, and a TDS2014B at about $400 gives you the same four channels at 100 MHz with USB.

What is the difference between the TDS2024B and TDS2024C?

Both are 200 MHz, four channels, 2 GS/s, 2.5k points, with front and rear USB. The C has a 5.7-inch active TFT display, 16 automatic measurements instead of 12, built-in limit testing and data logging, and shipped with TPP0201 probes instead of the P2220. Used, the difference is where it ships from: on 7 October 2026 there were four US TDS2024B listings and no US TDS2024C listings at all.

Why are all the TDS2024C listings on eBay from China?

Large volumes of the C series left Asian factories and schools and are now sold by a few drop-ship operations under many eBay accounts, with titles that end in tags like "*yiso" or "&lhy". eBay's "results matching fewer words" block ignores the US-only filter, so they appear even when you filter. Their median asking price was $620 on 7 October 2026. The risk is the return: a 2 kg scope back to China at your cost.

Does the Tektronix lifetime warranty transfer to a used TDS2000?

No. It covers the original end-user purchaser only, requires proof of that purchase, and is not transferable. If the original owner sold the scope within three years, the warranty ended three years after their purchase anyway. Treat a used TDS2000B or TDS2000C as having no warranty, and treat "lifetime warranty" in a listing title as decoration.

Can a Tektronix TDS2012B be upgraded to 200 MHz?

The TDS1000B and TDS2000B series share one firmware, and hobbyists have patched the model block at the end of the ROM to make a lower model report as a TDS2022B. The patched scope will run, but its frequency response above the original bandwidth is not flat, a channel-count mismatch bricks the unit, and the result is not a TDS2022B. For a buyer, it is a reason to match the model on screen to the bezel and the rear label before paying for bandwidth.
