The internet can be a wonderful resource of information... my local branch #f07 has a #signalgenerator Adret Electronique 7100D, a device at least 10 years older than me... most manuals you find are in french, but another member found a lot of information in english.
now I can not only test if the #hermeslite2 does receive anything on #50mhz but also how well it performs above its nyquist frequency of 38.4 MHz ( half the samplerate of the #ad9866 in the #hl2 )

I've written this micro-website blog on the Fourier series, and how it may be applied to analysing waveforms produced by signal generators. It may be useful to someone.

I've created a free online Audio Signal Generator, that works straight out of the browser. Which you may or may not find useful.

O M G. 🚨CUTENESS OVERLOAD🚨

I was actually debating the necessity of this little Arbitrary Generator- after all I have a Siglent SDG 1032X - but wow this is a keeper! 😃🥰

First impression is really good, seems reasonably accurate in frequency and amplitude and it’s super easy to operate, haven’t touched the manual yet.

We’re so privileged (spoiled) today. 20 years ago, performance like this was almost unheard of for any kind of private use.. Today people would likely argue that this is an ‘entry product’ 🤷🏼‍♂️🙂

Clearly I’ll recommend this for anyone setting up a small bench at home 👌🏻🙂

More tests to follow 👍🏼

Ist schon spannende Technik, aber ich hätte das Gerät an jemanden gegeben, der sich mit der alten analogen TV-Technik auskennt und das Equipment hat, den #Signalgenerator wieder in Betrieb zu nehmen. Nur zum auseinanderrupfen ist's doch ein wenig schade drum.

Hat mir meine Kollege gerde gezeigt... ein mini #Oszilloskop mit #Komponententester und #Signalgenerator und #Akku für schmales Geld.

Ja es ich weiß es ist kein #Tektronix oder der gleichen, dafür kostet es aber auch nur ein Bruchteil. Und um mal schnell nen Signal zu identifizeiren oder nen Transistor auszumessen sollte es reichen :D

Have. The input isn't very accurate (noise) but for that extra channel you didn't have, it could be a lifesaver.

And it's small enough to get a permanent home in my already over-full toolchest.

And believe it or not, it has a built-in signal generator.

For about US$20.

A Nixie Clock, the Hard Way

Notice: no vintage Hewlett Packard test equipment was harmed in the making of this overly complicated Nixie clock. In fact, if anything, the HP 5245L electronic counter came out better off than it went into the project.

Beautiful hand-wired backplane in the HP 5245 counter.

We mention the fate of this instrument mainly because we've seen our fair share of cool-looking-old-thing-gutted-and-filled-with-Arduinos projects before, and while they can be interesting, there's something deeply disturbing about losing another bit of our shared electronic heritage. To gut this device, which hails from the early 1960s and features some of the most beautiful point-to-point backplane wiring we've ever seen, would have been a tragedy, one that [Shahriar] wisely avoided.

After a bit of recapping and some power supply troubleshooting, the video below treats us to a tour of the Nixie-based beauty. It's a wonderful piece, and still quite accurate after all these decades, although it did need a bit of calibration. Turning it into a clock non-destructively required adding a little bit of gear, though. Internally, [Shahriar] added a divide-by-ten card to allow the counter to use an external 10-MHz reference. Externally, an ERASynth++ programmable signal generator was used to send a signal to the counter from 0 Hz to 23,595.9 kHz, ramping up by 100 Hz every second.

The end result is the world's most complicated 24-hour clock, which honestly wasn't even the point of the build at all. It was to show off the glorious insides of the counter, introduce us to some cool new RF tools, and as always with [Shahriar]'s videos, to educate and inform. We've always enjoyed his wizardry, from his look into automotive radars to a million-dollar scope teardown, and this was another great project.
