Cleveland, O.— Model 5201 data acquisition system has four isolated, high-speed channels with one that multiplexes to eight additional inputs. Channels have 16-bit resolution, speeds up to 100 kHz, and full scale accuracy of 0.03%. Each channel has independent gain configurable on-the-fly via USB and independent measuring rates. It has 4-pole analog Butterworth with 10-kHz breakpoint and 5-pole digital Butterworth filters. Peak signal isolation between channels is 400 V dc. Other capabilities include bridge excitation for resistive loads, and four TTL trigger lines assignable to any channel. Keithley Instruments Inc.
