Hi All, Just curious if anyone here has used a wide-band oscilloscope (along with a signal source, of course) for duplexer and/or filter tuning?
I use an older Tektronix 7904 500mhz scope along with an HP 8640B Signal Generator and it works great. I can't really measure filter response, but I can see amplitude changes both large and small very well, which allows for quite precise tuning. I've tuned a couple of pass/notch type duplexers and several notch-only units with this setup and they all work nicely. Anyway, wonder if anyone else does this and general comments on the technique. Thanks! - Darrell/KA7BTV
