High Speed AD Storage Device: PH304-024/1CH


The High Speed Storage Device: PH304-024/1CH records high-speed/large-volume signals. This unit contains a circuit board which has a 1 channel A/D converter and a 2-MW memory storage unit. The circuit board configuration is made up of units whose volume of memory is dependant on the number of built-in curcuit boards.
Sampling frequency is arbitrarily configurable to 20, 40, 80, 160, and 320ns. The recorded data is transmitted to your PC via P-I/O port.
