The Advantest R5363 is a high-speed frequency counter engineered for precision measurements across multiple parameters. It performs frequency, cycle, pulse width, and totalized count measurements with continuous operation capability—acquiring up to 14,000 data points without measurement interruption. The instrument delivers 10-digit resolution per second using a 100 ns reference clock and Advantest’s proprietary Reciprocal Method, which magnifies fractional parts up to 1,000 times to achieve measurement sensitivity equivalent to a 100 ps clock. Built-in data processing includes OK/NG decision logic, PPM display, and statistical computing functions for immediate result analysis.

– Compatibility & Integration
The R5363 connects to test systems via standard GPIB interface. BCD and DA output units (R13017 and R13018) enable integration with legacy digital and analog control systems. Optional battery pack (TR15801A/B) supports portable or field measurement scenarios. Optimal performance requires operation in a stable, temperature-controlled environment free from vibration, moisture, and magnetic interference, with minimum 10 cm clearance around air vents.
