The 1271 was a pretty nice design, both in terms of the circuit and the ergonomics. I had one, probably purchased around 1978 (it came out in 1974, discontinued in 1987) and used it in my home lab. It always worked very well, but I found it a bit difficult to use in the more advanced circuits I was working on, since it only had the most basic waveforms. I sold mine on eBay when I acquired a reconditioned HP that I still use, which itself has been partially supplanted with a digital function generator that is even more flexible. The one thing that always bugged me about the 1271 was that Heath put a standard round LED behind the triangular shaped "arrow" opening next to the Frequency dial, and they did not include a diffuser, so instead of a nice illuminated triangle, it just had a round lighted dot in an otherwise dark triangle. There is good reason why probably most Heathkits of this so-called "Post New Look" styling are missing their combination carrying handles/kickstands.....the design sucked! The star washer Heathkit provided to give enough 'lock' to the handle/stand was too weak, and when the equipment sagged, the washer's teeth dug gouges into the aluminum case, further reducing surface area and making the 'sag' worse and worse. I think only on the oscilloscopes of that period did Heath include proper detent locks for the handles/kickstands.
Thanks Jeff, always enjoy your reviews of so many of the boxes I built back in the day and of course your Classic book is a great reference! 73 - Dino KLØS
@@itrstt66 Maximum output voltage is 10 volts peak-to-peak and the minimum would be with 70dB attenuation, about 1 uV, although in practice I don' t think it will go that low.
@@jefftranter yes i get that it outputs 10vpp, thing is that it could be 10vpp from -5v to +5v, from 0 to 10, 20 to 30. What are the voltage values for the peaks?
@@itrstt66 The output voltage is approximately centred around zero volts. There is a DC offset adjustment to set it to zero, but not all versions had this adjustment. My unit was modified to optionally switch in a capacitor so that the output was AC coupled and there would be no DC offset.
