Hi guys, I'm in the market for a signal generator -- I'm trying to get a PLL to = lock onto an RF (low hundreds of kHz) carrier, then use a phase detector = to decode the ~12.5bps phase-modulated data that's riding on top of the = carrier. Yes, I'm making a Radio 4 Timecode decoder. Though IIRC the BBC spec = calls it "LF Radio-Data". Catch: the Hameg signal generator I'm using now doesn't do any form of = modulation besides some quick-and-nasty AM which I've been using to = tweak the filters. 1024-point 12-bit arbitrary waves is about as = advanced as it goes, which isn't going to get me a 198k sine with PM data. So I'm looking at a new signal generator -- the Agilent 33220A and Tek = AFG3021B are on my shortlist and have basically identical specs (aside = from the Tek's bigger display). I'm leaning towards the 33220 because = it's smaller than the Tek (desk space is at a premium), and it's going = to be tethered to a PC most of the time anyway so the large LCD is = pretty irrelevant. It's also about =A3200 +VAT cheaper... Now before I plunk down ~=A31k +VAT on one of these boxes... has anyone = actually used one of these boxes? Any comments or criticisms? Most of what I'll be using it for is <20MHz or so RF testing, bandwidth = tests / frequency response of amplifiers, that sort of thing. I'm also = open to suggestions of similar equipment from other manufacturers...
