DP3000 differential probe

The DP3000 differential probe is a high-performance product under the Micsig DP series high-voltage differential probe, upgraded from the previous model DP20003 with enhanced performance and a newly designed, more compact appearance (). This probe integrates advanced features to cater to various high-voltage testing scenarios, and it is compatible with other models in the series such as DP700 differential probe, DP1500 high-voltage probe, and DP7000 100MHz probe, each serving specific testing requirements.

Key Features

• Bandwidth: The DP3000 series includes models like DP3005, which is a 500MHz high-voltage differential probe, ensuring accurate measurements in high-frequency environments ().
• Max. Input Differential Voltage: It supports 300V(100X) and 3000V(1000X) (DC+AC PK). For higher voltage needs, the series offers 7000Vpk differential voltage probe such as DP7000 ().
• Noise Performance: As a low noise high-voltage probe, its noise under full bandwidth is ≤400mVrms (100X) and 500mVrms (1000X), ensuring high sensitivity for small signal detection ().
• CMRR: Being a high CMRR differential probe, it boasts excellent common mode rejection capability with specifications: DC: >-80 dB, 100kHz: >-70dB, 20MHz: >-40dB, 120MHz: >-26dB, suitable for high common mode voltage floating measurements ().
• Interface: Equipped with a BNC interface differential probe, it can work with any oscilloscope, enhancing compatibility ().
• Design: Based on optical isolation differential probe technology, it features low noise, excellent amplitude-frequency characteristics, and a compact design. It also includes one-press auto zero, dual-range, and overload alarm functions (, ).
• Input & Output Impedance: The input impedance is 20MΩ/0.5pF (differential) and 10MΩ/1pF (each input to ground), with an output impedance of 50Ω, minimizing load effect and improving measurement accuracy ().
• Applications: It is ideal as a floating measurement differential probe, motor drive design probe, and inverter UPS test probe, also suitable for electronic ballast design, high voltage isolation measurements, and more ( to ).
