I Had a big difference configuring for to use ASIO driver in measures. The programs that allow ASIO driver is Arta and Rightmark.

Sound Card EMU 0404 PCI with Chipset ATI (using PCI card may have problems with new chipsets Intel) SO- Windons XP 32.

I believe it is related to latency WDM in Rightmark the value was 142ms, ASIO driver the value was 50ms.

Has anybody here used vector signal analyzers like the 89410a or the 89441A instead
of the usual FFT analyzers? In comparison to the newer Stanfords or HP/Agilent FFT
analyzers they seem not to be costly, and the BW is 10 MHz vs. 50 KHz on many HPs
when used dual channel.

A source is also there, cross spectrum/waterfall/spectrogramm, everything available,
and the RF unit is not needed for AF people.

regards, Gerhard

Interesting option but they are $2K+ on eBay and will require some learning to use. The Omichron is an alternative VNA with similar coverage .
I can get the VNA functionality along with good post processing from Praxis. Once you understand the VNA well you can do really interesting things with one. I use an 8753 often so I'm no stranger to the concept, but its way beyond most audio hobbyists.

I find the Anritsu MS420B to be better suited for audio and HF. It covers a freq range of 10Hz to 30MHz. When calibrated, it easily exceed all specs and hold specs well. But there are no spare parts - an obsolete model. but built like HP gear - lasts forever.
