Agilent/Keysight 34465A

The Keysight 34465A is a 6½ digit digital multimeter engineered with Truevolt technology to deliver measurement accuracy and noise rejection in demanding test environments. Its patented analog-to-digital converter architecture minimizes extraneous factors—AC ripple, power line noise, injected current, and input bias current—ensuring high-confidence results across electronics testing, research, and manufacturing applications.
