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.
