32-Channel Rackmount Frequency Measurement System

Measure up to 32 signals simultaneously with a true parallel, rack-mounted frequency measurement system. Each channel features a dedicated counter, eliminating multiplexing errors and ensuring accurate, real-time results across a wide frequency range from kHz to 100 MHz. Built on a high-resolution heterodyne architecture, the system delivers ppb to ppt-level performance for both short-term measurements and long-term stability analysis. With flexible gate times, scalable expansion, and a compact 1U design, it is optimized for production testing, validation, and precision frequency characterization. Key Features 32 Independent Channels Dedicated counter per channel enables true parallel measurement with no switching delays Simultaneous Acquisition Capture all inputs in real time to increase test speed and throughput No RF Switching Required Eliminates switching errors and improves measurement repeatability High Channel Isolation Minimizes injection locking and cross-channel interference Wide Frequency Coverage Measures from low kHz up to 100 MHz using direct input or down-conversion High Measurement Resolution Delivers ppb to ppt-level precision using heterodyne techniques Flexible Gate Times Adjustable from 10 ms to 24 hours for dynamic or long-duration measurements Zero-Dead-Time (Optional) Continuous acquisition with no gaps in measurement data Integrated NCO (0.5–100 MHz) Supports internal mixing for multi-frequency test scenarios High Throughput Performance Up to 1600 measurements per second via high-speed communication Onboard Data Buffering Stores up to 4096 readings per system for efficient data handling External 10 MHz Reference Enables synchronization with high-stability lab references ADEV & Stability Analysis Ready Supports Allan deviation and long-term frequency characterization Scalable System Architecture Daisy-chain multiple units to support large channel counts Compact 1U Rackmount Form Factor Maximizes channel density while minimizing rack space PC-Controlled Operation Integrates easily into automated test environments Applications Production & Manufacturing Test RF Test & Measurement Signal Processing Validation Sensing & Instrumentation Systems
