I have a crappy BK Precision function generator. It does what I need, more or less, but its crappy. Feels crappy to use. Dials are lighter than 80s American car steering, and worst, the frequency drifts if you leave it running overnight on a task etc. I dont need the latest, I just want a really nice piece that feels good to use and I know will last. Since I don't know this type of piece that well, I would like to know what everyone considers a really good classic unit. Please note, I don't want anything older than perhaps late 80s, just to contextualize what sort of era I am willing to go back to. I need a general purpose unit that goes all the way down in frequency, I see units that start at 10mhz etc, I dont want that. It would also be nice to read the voltage output of the signal, not just db or other scaling. |

Why used? Nowadays you can buy very nice low cost function generators like Feeltech FY6900 or the UNI-T UTG932E. Any used function generator is either crap or way more expensive compared to the units from Feeltech and Uni-t. Don't make the mistake thinking that older (>10 years) units are somehow better; they aren't. Technology has advanced a lot and nowadays you can build a very good function generator from cheap common parts that don't run extremely hot or are under stress. |

A cute display is, cute. If we had more serious companies, we'd have products which had the right characteristics, perhaps THEN introduce a cute display. The caveat is that if you spend a Gorillion Dollars, you can get a new nice piece of way overpriced kit like a Keysight. But we get Rigol. |

And yet cost wise the Feeltech FY6900 or the UNI-T UTG932E are the best choices if all you need is a simple, general purpose function generator. You can buy the Uni-t from various local suppliers in case you are worried about warranty & support. In the end it is your money; spend it wisely. |

What scope might you be pairing it with......there are serious reasons for these questions. |
