The Keysight/Agilent/HP E1333A is a 3-channel universal counter module for VXI test systems, delivering precision frequency, period, pulse width, time interval, and event counting measurements. This register-based B-size module integrates into single-slot VXI mainframes to enable automated test environments and benchtop signal analysis with software-selectable measurement functions and edge triggering.
Technical Specifications
Measurement Capabilities
The E1333A provides six primary counter functions: frequency measurement, period average, pulse width measurement, pulse width average, time interval measurement, time interval average, totalize, and ratio measurement across multiple channels.
