This is a Keysight N6781A Source/Measure Module. This unit is in GREAT condition, and guaranteed fully operational. I have TWO of these, one per bid.

The Keysight N6781A is a source / measure unit (SMU) designed specifically for the task of battery drain analysis. Whether the device under test (DUT) is an eBook reader, MP3 player, mobile phone, or pacemaker, the N6781A’s seamless measurement ranging, programmable output resistance, and auxiliary DVM combine the best set of advanced features on the market for battery drain analysis. When used with the 14585A Control and Analysis software, the N6781A becomes an even more powerful battery drain analysis solution, offering additional insights into your measurements.

Seamless Measurement Ranging

Seamless measurement ranging eliminates the challenges of measuring dynamic currents. With seamless measurement ranging, engineers can precisely measure dynamic currents without any glitches or disruptions to the measurement. As the current drawn by the DUT changes, the SMU automatically and instantaneously detects which current measurement ranges will return the most precise measurement and changes to that range seamlessly. When combined with the SMU's built-in 18-bit digitizer, seamless measurement ranging enables unprecedented effective vertical resolution of 28-bits. This provides unrivaled productivity gains and insights into power consumption by enabling engineers to see the complete current waveform they have never seen before, from nA to A, in one pass and one picture.

Other Features and Benefits

glitch-free sourcing and measurement: change output and measurement ranges without any glitches
