Universal Frequency Counter
SS7000 Series 200MHz Universal Frequency Counters/Timers serve all of your frequency and time interval measurement needs. 4 available models offer resolution capabilities up to 11 digits/s. Single-shot time interval measurement can be resolved down to 25ps typical. Meanwhile, additional RF channel options maximum to 40GHz can be added to meet your special test requirement.
Applications
Telecommunications & RF Testing
Measures frequencies of multiple communication signals (e.g., GSM, LTE, 5G, Wi-Fi).
Verifies transmitter/receiver stability by comparing multiple channels.
Monitors clock synchronization in base stations and network equipment.
Electronics & Embedded Systems Development
Tests clock signals in microcontrollers, FPGAs, and DSPs across multiple channels.
Measures PWM (Pulse Width Modulation) frequencies in motor control systems.
Validates oscillator stability (e.g., crystal oscillators, TCXOs, OCXOs).
Industrial Automation & Robotics
Monitors encoder and servo motor frequencies for precision control.
Checks timing signals in PLCs (Programmable Logic Controllers).
Validates sensor outputs (e.g., ultrasonic, optical encoders).
SS7000 Series frequency counters can measure maximum 200 MHz frequency on CH1 and CH2.
CH3 can be configured with maximum 40 GHz option to meet higher frequency measurement.
SS7000 Series can provide minimum 11 digits/s measuring resolution, which makes the high accuracy measurement possible.
Besides the basic functions, statistics such as multi-average, max, min, PPM are also available.
