Agilent / Keysight E1740A Time Interval Analyzer Module

The Agilent/Keysight E1740A is a 2-slot, C-Size VXI time interval analyzer module delivering high-resolution timing measurements for precision jitter characterization and synchronization analysis. This message-based, SCPI-compatible card forms the core component of the E1725C VXI system and rapidly collects large datasets into histograms, enabling statistically solid timing analysis across edge capture and pulse series configurations.

Technical Specifications

• Form Factor: 2-slot, C-Size VXI module


• Interface: Message-based VXI, SCPI compatible


• Edge Timing Rates (configuration-dependent):

Up to 80 MHz pulse series with 12.5 ns minimum continuous interval and 3.2 µsec maximum interval

Up to 40 MHz edge capture with 25 ns minimum continuous interval and 104 ms maximum interval

Data Collection: High-speed histogram acquisition supporting large sample populations for enhanced statistical confidence

Key Features

• High-resolution timing capture with sub-nanosecond precision


• Flexible measurement modes for both pulse and edge-based timing analysis


• Rapid data aggregation into statistical distributions


• Integrated within E1725C systems for modular timing test solutions

Typical Applications

• Jitter characterization and clock distribution analysis


• Telecommunications and SONET/SDH timing validation


• VCO/PLL phase noise and stability measurement


• Network synchronization verification


• Data storage device timing performance


• Radar and surveillance system timing analysis


• Digital design timing closure and validation


• High-speed mechanical system synchronization

Compatibility & Integration The E1740A integrates directly into VXI chassis architectures and operates under SCPI control. Compatible with HP E1742A/43A/44A/46A/48A analysis software packages for application-specific measurement automation and reporting.
