ODP6000B Series of Probes

The ODP6000B series represents the newest generation of optically isolated voltage probes, offering exceptionally high common-mode rejection ratio (CMRR). Unlike conventional differential probes, which experience a rapid decline in CMRR at higher frequencies, the ODP6000B maintains strong performance across its entire bandwidth. This makes it especially effective for accurately capturing small voltage signals—such as the gate drive voltage of the upper MOSFET in a half-bridge circuit—even in environments with significant common-mode interference. By leveraging advanced optical isolation technology, the ODP6000B series provides a cost-effective solution for tackling these demanding measurement challenges.

Series Features

• Can be calibrated and zeroed online without disconnecting from the tested equipment.
• Multiple attenuators available, able to meet the measurement requirement of different voltage.
• Extremely high CMRR.
• Bandwidth over 1 GHz.
• Isolation voltage over 60 kV.
• High accuracy and stability in wide temperature range.
• Smaller size.

Applications

ODP6000B series can be widely applied in the R&D, debugging or maintenance of switching power supply, motor driver, new energy inverter, converter, LED power supply, household appliances and other electrical power devices.

• Floating signal test.
• Measure the gate voltage drive of power devices like Si/SiC/GaN.
• Small signal measurement of differential mode under high common mode voltage.
