U8976 For the MR6000 and similar products
Note: Use it by installing it in the Memory HiCorder. Input code kind is not included so purchase separately.

Blazingly fast sampling that won't fail

The High Speed Analog Unit U8976 delivers a 30 MHz frequency band in addition to high-speed sampling at 200 MS/s. It has the performance needed to accurately capture switching waveforms during inverter testing, an application where high efficiency is critical. Adapted to the Memory HiCorder's direct input feature, it can accept inputs of up to 400 V DC.

Accurately measure inrush current with high-speed sampling

Combine the High-Speed Analog Unit U8976’s 30 MHz frequency band with the Current Probe CT6711 to measure inrush currents and minuscule currents.
Power can be supplied to current probes by using the Power Probe Unit Z5021 (MR6000 only).
