These multimeters have the precision and versatility to handle your most demanding measurements on the bench or in a system. Their dual graphical display can reveal signal quality issues like drift, intermittent, and stability by viewing the measurement data as a real time TrendPlot™, histogram, or statistics using the unique analyze mode. Resistance and current ranges have been extended to cover the widest range possible. The 8846A’s resistance measurement range is extended from 10W up to 1GW with a resolution of up to 10mW. For DC current measurements, the 8845A and 8846A ranges from 100mA to 10A with a maximum resolution of 100pA. Patented split terminal jacks for 2x4 ohms function allow you to perform precise 4-wire measurements with only two leads instead of four. The 8846A increases basic Vdc accuracy to 0.0024% plus adds measurements like capacitance, RTD temperature, and dBm. The 8846A also includes a USB port to connect standard USB memory devices for convenient storage or transfer of critical data to your PC. Both instruments include RS-232, IEEE-488, and Ethernet interfaces, as well as popular DMM emulation modes that make systems integration a simple task.
