DC890B

Demonstration circuit DC890B along with PScope™ software provides a USB based Windows PC hosted digital data acquisition system supporting CMOS/LVDS output ADCs up to 250Msps. The PScope evaluation software automatically detects the DC890B and can also detect many of the standard ADC demonstration circuits boards. The DC890B will not enable LVDS mode unless an external 6VDC power source is available. This system provides for fast and easy performance evaluation of high speed ADCs. DC890B collects up to 256K word samples and then performs various analyses on the data including calculating SNR, SINAD, THD, SFDR and ENOB. The digitized input, an FFT of the collected data, the primitive wave of the sample set or an IFFT of modified frequency domain data is plotted to a display window to facilitate analysing distortion products and sources.

• Must be powered from an external 6VDC ±0.5VDC power supply when operating in LVDS mode
• When operating in CMOS mode, the external power supply is optional
• connected to ADC demonstration circuit via a 100-pin edge connector
• Connected to PC by USB A-B cable and to optional power supply either by 5mm power plug or by turrets
