Yokogawa Test & Measurement Corporation announces its new 720252 1 MS/s 16-bit isolation module, featuring wide-range DC offset-adjust capability, and the 720301 power measurement module, delivering guaranteed DC/AC waveform accuracy.

An evolution of the existing 701251, the 720252 covers a wider offset adjustment range than general digital oscilloscopes, enabling precise measurement of even the smallest DC voltage and current changes from batteries or sensors. Its offset adjustment function is capable of cancelling a broad spectrum of DC bias, such as battery voltage, DC voltage, and DC current. The module also enables the simultaneous observation of DC levels and microvoltage fluctuations, as low as 1 mV/div for battery applications. Another significant improvement introduced by the 720252 is its Hi Z (> 1 GΩ) input impedance mode, capable of reducing the loading effect of the input circuit on a battery cell.
The 720301 reduces setup complexity, providing an all-in-one solution that correlates power consumption and generation with parameters including temperature, strain, acceleration, and sound. The module features one direct voltage input and one current sensor input, integrating with the power analysis functions of the DL950 or SL2000 to ensure maximum accuracy in measuring DC and AC voltage/current waveforms. These features are supported by a user-defined measurement period for power calculations (from 0.1ms), cycle-by-cycle power calculations, and trigger functions on power measurement parameters and harmonic orders.
