Digitizer cards handle wide-ranging applications
-- Test & Measurement World, 5/1/2009 2:00:00 AM
Engineers often use high-speed digitizer cards for radar, communications, and disk-drive testing. The Razor series of PCI digitizer cards provide two or four channels with 16-bit resolution and sampling speeds of 100 Msamples/s or 200 Msamples/s. The 200-Msamples/s models feature 125-MHz analog bandwidth; the 100-Msamples/s models have 65-MHz bandwidth. All models feature 12-bit ENOB (effective number of bits).
The Razor cards have separate ADCs for each channel, so you can simultaneously sample on all channels. You can trigger acquisitions on an internal clock or an external clock and store 128 Msamples of data (options up to 2 Gsamples).
Software support includes drivers for Windows XP and Vista. The cards also come with GageScope Lite edition, which you can use to verify card operation and to make measurements. Standard and professional editions are optional, as are software development kits for C/C#, LabView, and Matlab.
Prices: two-channel card—$6495; four-channel card—$8995. Gage Applied, www.gage-applied.com.
