¿ªÔÆÌåÓýI worked at a boutique hifi shop for a few years around 2015. I had an 8640 and it was fime for aligning FM tuners, as well as AM/SW and the occasional communications receiver. The shop had a Sound Technologies ST-1000, but the other technician laid total claim to it. I got a Heathkit generator for working on? stereo FM decoders. Considering the technical standards and audio processing of stations in this area, a tip top quality alignment with a sweep generator would? be a waste of time.? I did borrow and use a spectrum analyzer with a tracking generator to repair a really beaten up Marantz 10 tuner. Trying to align an IF with Butterworth filters can drive you crazy, especially if you don't have the secret factory repair manual. I never had an unhappy customer. ??

Probably hard to find these days, but an 8690 sweeper mainframe with the solid state 8698 100 KHz to 110 MHz plugin should do the job. The 8698/8690 combo has a full range calibrated attenuator on the output(+10 to -110 dBm) and both internal and external modulation capabilities are available. But- it IS big and heavy!

Does anyone know of a HP signal generator thats got a sweep section for FM (87.5 - 108 MHz) tuner alignment? The old Sound technology ST1000 was ideal for that but now long out of production but seeing that in the UK at least the FM Broadcast band is to be retrained till at least 2030 and we do have some FM Rebroadcast receivers to look after, that would be a useful unit to have! Thanks if anyone can recommend an HP one... -- Tony Sayer |
