content: Hi, I'm here to sell my Exact 524 Function/Pulse generator. I've had this unit for some time and am reluctant to let it go, but I have my eye on a low-cost 7904 mainframe that I want to buy. (I try to keep my hobby as money-neutral as possible, meaning I don't spend extra money on it, but rather sell and buy things as needs come and go, or in this case, desires)I have this listed on eBay to make shipping to other parts of the nation or world easier.EEVblog members get a $10 discount. Just message me on eBay or reply to this topic to let me know the buyer is an EEVblog member. If you are an engineering student, you get another $5 off.eBay link here:https://www.ebay.com/itm/166590213570?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=CTI57OxBQDq&sssrc=2047675&ssuid=CTI57OxBQDq&widget_ver=artemis&media=COPYThis is located in Sacramento California.What this is:This is an Exact Model 524. Exact as in the company from Oregon state, not the adjective. The Exact 524 is a pulse/function generator, meaning it can operate as a function generator or a pulse generator. The available functions for this unit are, sine, triangle, ramp, square, positive pulse, negative pulse.It also features a VCF input, or voltage controlled frequency. It also features a number of different outputs such as TTL and ECL. Delay is also available.The maximum output power for this unit under a 50 ohm load with the sine function seems to be two and a quarter watts. My two 100 ohm 1/4 watt resistors tied in parallel get very hot.Condition:This unit is in perfectly fine working order as far as I can tell.Physical cosmetics are okay for its age I guess. It has a cracked bezel (that I glued back together), and some minor scratches. It also has some crusty sticker residue.The switches are a bit scratchy, so if you aren't getting any signal output, or something is wrong, you can try wiggling the switches a bit. I've tried using isopropyl and BW-100, and they have improved the problem a lot, but the problem still persists to some extent.I've tried calibrating this unit as best as I can, but I can't find a proper service manual for it. The dials seem to be accurate enough though for most applications.It looks like the unit may have had a lockable dual-duty tilt-bail carrying handle, however, it looks like it was purposefully removed to allow accommodation for shelf mounting by the previous owner.What you'll get:You'll get the Exact 524 as described above. Only that. You will not receive the Tektronix 2230 used to test the device, nor any cables apart from the power cable.Questions?:If you have any questions at all, feel free to reach out to me. I'll try my best to answer your question.Ei:Q: Do you know the date of manufacture?A: By the looks of IC date codes inside, during or after the 17th week of 1984 was the date this unit was manufactured.Q: By how much can you lower the price?A: Send me your best offer first.Q: Can I have the Tektronix 2230, the BNC cable, and the whole bundle of a mess of junk behind the Exact 524 included for free with the Exact 524?A: Hell no.Note:Make sure to check out my other sales! I sell a little bit more than just this function/pulse generator!(I really like USPS shipping, as you have probably noticed with the shipping options)
