Frequency, time, and photon counters for precise measurements in electronics, optics, and research applications. The range includes frequency counters, time interval counters, photon counters, and multichannel scalers with high resolution, fast measurement rates, and stable reference sources.
3 GHz frequency measurement with 10-digit resolution, AC/DC switching, variable threshold, multiple measurement modes and USB control for flexible signal analysis.
2-channel photon counter with up to 200 MHz, 5 ns gate resolution, discriminators, gated/continuous modes, gate sweep for time resolution and GPIB/RS-232.
5–10 ms time bins, up to 100 MHz counting, 1k–32k bins, built-in discriminator, no inter-channel dead time, screen analysis, and GPIB/RS-232 and 3.5" storage.
25 ps time resolution, 0.001 Hz–1.3 GHz frequency range, 11-digit resolution, phase and time measurement, statistical functions and GPIB/RS-232 interface.
Rubidium time base with 11-digit resolution, 2 GHz prescaler, 10 MHz reference output, statistical functions, Allan variance and GPIB/RS-232 interface.
