Dual Channel Sampling Multimeter, 7 1/2 Digits. Two high-precision, 7½-digit DMMs in a 1U high, full rack width chassis No space requirements between instruments minimizes rack space Capture waveforms or identify transients with two 1 MSa/s 18-bit digitizers Trigger a waveform measurement on a signal level, a rising or falling edge, a window, or a digital trigger Store up to 27.5M timestamped readings on a waveform Basic one-year DC Voltage accuracy as low as 14 ppm 10 nV, 0.1 uΩ, and 1 pA sensitivities for making high resolution low level measurements such as measurements of portable device sleep currents High accuracy, low resistance measurements with offset compensated ohms, four-wire measurement, and dry circuit functions Auto-calibration improves accuracy and stability by minimizing temperature and time drift USBTMC-compliant and LAN LXI-compliant Interfaces Reduce test time by executing test scripts with the Embedded Test Script Processor, which saves PC command communication Overhead Tight synchronization between the two DMMs using TSP-Link® communication Reduce life cycle costs with a two-year calibration interval Remote Interface: LAN (RJ-45 connector, 10/100BT; Virtual Front Pane) USB Device (front Panel, type B): 2.0 full Speed, USBTMC compliant USB Host 8fron Panel, type A) : USb 2.0, Support for Flash drives, FAT 32 Dimension (HxWxD): Rack Mount: 44 x 483 x 696 mm (1.7 x 19 x 27.41 in.)
