The 7½ digit DMM7510 combines a precision, high-resolution digital multimeter (DMM), graphical touchscreen display, and high-speed, high-resolution digitizer to create the first graphical sampling multimeter. With pA-level sensitivity and 1Msample/s sampling, it accurately measures ultra-low sleep mode currents and transmit drain currents from wireless devices. The DMM7510 succeeds the model 2010 and 2001, and provides noise performance equivalent to or better than many 8½-digit DMMs
