Agilent/Keysight E1752A

The Agilent/Keysight E1752A is a C-size VXI pulse distribution amplifier that buffers and distributes clock signals, timing pulses, and broadband waveforms across up to six isolated outputs. Operating from 100 kHz to 10 MHz (or 1 pps to 10 million pulses per second), the module accepts input levels between +7 dBm and +19 dBm and maintains phase and frequency integrity across varying environmental conditions. High port-to-port isolation and low crosstalk make it suitable for precision timing distribution in laboratory, factory, and automated test equipment systems.

Key Features

• Built-in automatic gain control (AGC) for phase stability and rapid deployment without manual level adjustment


• High isolation between output ports to minimize crosstalk in multi-channel distribution


• Channel fault alarm with front-panel status indicators for system monitoring


• VXIbus register access enables real-time signal presence/absence detection on individual channels


• Preserves input signal phase and frequency characteristics under temperature and humidity variations

Typical Applications

• Precision clock distribution in ATE and test systems


• 1 pps timing reference distribution


• Broadband pulse and sine wave buffering


• Multi-channel signal distribution in synchronized measurement environments

Compatibility & Integration Designed as a plug-in module for VXIbus systems, the E1752A integrates via register-based VXI controller communication. Accepts standard clock signals, timing pulses, sine waves, and pulse trains across its 50 Ω input.
