  1. Calibration is priced by the work an instrument requires — bench time, test points, reference standards. It is not priced as a fraction of what the instrument is worth. That single fact reshapes what used test equipment is actually worth once it's tested across a price range.

    At one accredited lab, calibrating a $475 Keithley multimeter runs about 12.6% of its sale price, and closer to 23% at retail rates. Calibrating a $78,500 20 GHz oscilloscope runs about 1.2%. Same service, wildly different weight on the sale price.

    The counterpoint: large refurbishers like Keysight and Tektronix recalibrate everything on intake regardless of certificate status. For that channel a fresh certificate doesn't save the buyer a cost they'd pay anyway. What it does is narrow the risk that the unit turns out to be a repair job.

    What that means for sellers, and why installed options and probe accessories often move price more than the calibration sticker, is in the full piece on used test equipment value.

  3. I noticed that I had a Pico Technologies PicoScope 2204A USB-based 2-channel 10 MHz oscilloscope with arbitrary waveform generator (AWG) that I bought back in 2021. I don't recall what I paid for it, but it now sells for $185 (with 2 probes as I got, or $149 without).

    Installing the software on Linux Mint Debian Edition 6 (LMDE6) was easy and it works well on the couple of laptop computers I've tried it on, so this might turn into something that I often pack with one as basic lab equipment.

    I was delighted to find that the software includes a spectrum analyzer function. (With the cheapest hardware, it tops out around 760 kHz, so it's not very useful, but easier to carry than my two HP units.) It also seems to have serial data decoding functions (which I haven't explored yet.)

    Pico is based in the UK, but seems to ship from Tyler TX. (National Instruments, based in Austin TX, has long offered similar products built around its LabView software.)
