Yokogawa oscilloscope high-sensitivity current probes

Two new high-sensitivity current probes are now available for the Yokogawa families of mixed-signal oscilloscopes and ScopeCorders.

The 701917, covering a frequency range from DC to 50 MHz, and the 701918, covering DC to 120 MHz, offer sensitivities ten times higher than previous models (typically 1 V/A) along with low noise levels of typically 60 µA RMS. They are ideally suited to the measurement of low-level currents from about 1 mA to 5 A.

The probes feature a slim, lightweight sensor head which is easy to use in confined spaces. Automatic zero adjustment and demagnetisation are accessed via a button on the termination box, making setup quick and easy. An overload/jaw-unlocked warning is included for added safety.

Connection to the instrument is via the front-panel BNC connector. The power can be provided from the oscilloscope’s probe power option or from a separate probe power supply.

Applications include tests on LED drivers, controllers and power supplies, evaluation of embedded power supplies, measurements of the power consumption of low-voltage devices such as FPGAs and tests on embedded components in domestic appliances.

The 701917 and 701918 probes are designed for use with Yokogawa’s DLM2000 and DLM4000 Series of mixed-signal oscilloscopes and the DL850E and DL850EV Series of ScopeCorders.
