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.

Have a chance to grab a fully working, very nice condition Hitachi V-1565 100MHz two channel analog oscilloscope for $95 locally.
I have an adequate digital 1 GHz two channel scope, but I’m intrigued with an analog one that has digital storage and cursors.
Any opinions on this one for the price and possible advantages (say in retro repair) of an analog scope (aside from the historical interest)?

And speaking of @ExtKits this is my 2026 haul from the #emfcamp #nightmarket . A mini computer, optical #theremin, a lightning detector, tiny #oscilloscope a #morsecode kit and of course, the #orphansauce.
One day I hope to find time to build all these! ❤️

i was recently gifted a Grundig oscilloscope from ~1977 IN PERFECT CONDITION (that is something that can casually happen to you(???)) - beside having YA, YB and X of course...it has a 5V intensity mod on the backside for the Z axis (did not get to try it yet though!).
anyway this is my new setup guys pls r8 my pc

Sometimes it’s helpful to have a digital and analog scope to look at the same thing.
I managed to get this HP 3497A test unit up and running, and roughly calibrated using a standard cell.

Any #vintage #electronics aficionados in #ireland interested in an apparently working vintage #oscilloscope?
Not my photo, not my ad, but this unit's price has been dropping steadily for a few weeks and I'd hate to see the seller decide this unit is worthless. Dates from 1985, 15MHz.
Comes with original manual, which I can't find online.

@ai6yr I have to share this. I was the lead on the PR team that helped launch this product back in 1996.
I LOVED this promo mug because a wave form showed up when you poured hot water in it, showing what people were missing with other 'scopes.
It was the hottest giveaway & I credit the marketing people at Tektronix for the idea & execution. I've kept in on my desk for 30 years! #Oscilloscope

Added some oscilloscope measured waveforms to my blogpost about the hc-sr04 ultrasonic distance sensor. Trigger pulse width was off from the expected width on linux. Ultrasonic pulses clearly visual as well

A while back I got a new digital 'scope. The one I'd been using was okay, but only 8-bit and had some other limitations. The vertical resolution was actually starting to make it difficult to get accurate-enough readings of some things I was working with.
The new one is 12-bit. That is likely to be better than I will ever need. I'm happy with it. Being several years newer (and a different brand) it brings some new #features to the table.
One is that you can use it as a digital logic analyzer - it can sample a whole lot of inputs (rather than just 4 analog channels) quickly if it only has to tell on from off. But you have to get a whole lot of #signals into the #scope before you can do that, so you need a #connector with a lot of pins/signals.
You could use something standard for this type of application (which is still going to be a limited-audience part), or a custom thing, but those options are expensive. So instead, if you're the manufacturer, you find a common (and therefore #cheap) #connector with lots of #pins, and you re-use that. Done and dusted!
They picked ... the HDMI connector. It's there at the bottom of the middle of the control panel. And in the manual is the prominent (not) warning:
> WARNING: Non-standard HDMI interface, Siglent device ONLY, or you will damage your device.
Yes, if you plug anything HDMI-related into this obvious #HDMI port, you will cause damage to your 'scope, or your other device.

Looking to turn my #Pico2 in a rudimentary #oscilloscope. Have been checking the ADC's samplerate and tried measuring an ultrasonic distance sensor's echo pulse. Not quite there yet, USB throughput is still a limiting factor.

Though a rudimentary DSO by today’s standards, I still find this 1980s era Tektronix digitizer plugin to be quite useful. At 100ms and under, it’s got a cool ‘continuous roll’ display that’s handy for slower signals.
This is one of several multi-bay plugins for the 7000 series, and it’s well suited for the 7603 mainframe, with its larger screen.

Question: I recently acquired an old TDS420A without probes (for free), getting the proper probes for it is going to be about €450. Should I just buy an equivalent modern scope? (€700-€800)
