You can get a 50 GHz 11801C with lots of good modules for a couple of percent of that number.

Thanks Phil, I found a price list in their product announcement here: http://www.agilent.com/about/newsroom/presrel/2010/27apr-em10050.html I wouldn't be surprised if the *probes* were in the high-four digits either -- maybe even hitting $10k+! It is kinda ironic that the 1st page there shows an eye diagram where you likely could get by just fine with a sampling scope... ....but I do expect it's pretty cool to see, e.g., a non-repetitive high-speed bitstream like SATA or PCI-E or similar at, say, 6Gbps go marching by... ---Joel

This can be a major problem with older Tek spectrum analyzers. Sometimes the first mixer is shot and so far I haven't heard from anyone of a successful low-cost fix, seemingly because this device is jammed into it really deep. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
