Utilization scenes

Observe microcurrents

[ SS-531 / SS-530 / SS-521 / SS-520 ]
In combination with a high-resolution oscilloscope, a 100µA stepped current can also be observed in high quality. The device also supports the observation of 100µA ripple currents.

Observe small currents with low noise

With a high S/N ratio and 10x output rate, you can observe microcurrents more clearly.

Observe high-speed rising currents

This device supports frequency bands up to 120MHz (SS-531/521), allowing current waveforms with high frequency components to be observed with low distortion.
