- Seesii TinyGTC ZC407 Handheld Frequency Counter: A cost-effective device with an ultra-wide 0.1 Hz—7 GHz frequency range, delivering precise data for RF development and frequency calibration. It features a built-in GNSS/GPS disciplined oscillator for measurement accuracy, and is equipped with a 4.0-inch HD touchscreen and a Micro SD card slot supporting up to 32GB for full-process data handling and storage
- Broad Frequency Coverage: The Frequency Dual Timer/Counter offers an impressive frequency range from 0.1 Hz to 7 GHz, encompassing both ultra-low and high frequencies. It accurately measures ultra-low-frequency and audio signals starting at 0.1 Hz, while the 7 GHz band supports mainstream wireless communications. With its extensive coverage and versatility, this single unit handles diverse full-band testing needs
- Dual-Channel Measurement: The device is equipped with two independent input channels (A & B) for simultaneous measurement and comparison, improving test efficiency and reducing errors. Channel A supports 0.1Hz–350MHz, extendable to 7GHz/12GHz with a GHz prescaler. Channel B is identical to Channel A, except that it does not include the GHz prescaler function. Ideal for interference troubleshooting, amplifier gain measurement, lab and field testing
- Ultra-High Precision: The TinyGTC features two independent counter/timers with 40 ps resolution, enabling gapless time, frequency, and phase measurements. Advanced reciprocal counting and ADEV stability deliver frequency-independent accuracy of 1e-11~1e-12 per second—providing lab-grade precision for research, development, and testing in TDR, pulse, and long-term stability applications
- GPS Synchronized Internal Clock: The TinyGTC incorporates a built-in GNSS/GPSDO that locks to GPS UTC for continuous calibration and long-term high precision. Its disciplined oscillator delivers stable 8kHz–150MHz frequencies as a clock source and accepts external references, including atomic clocks, to fully utilize its 12-bit resolution—designed for precision timing in communication base station testing, distributed sensor networks, and field research
- Built-in 4000mAh Battery: Delivers up to 5 hours of continuous operation on a single charge, meeting the demands of most testing scenarios. The USB-C port enables convenient charging and data connectivity
- Convenient PC Control & Data Transfer: This Frequency Dual Timer/Counter supports real-time data display and transmission. Built-in USB port enables remote control and direct access to measurement data via connected devices, and it is compatible with up to 32GB MicroSD cards for efficient data storage and sharing, meeting the needs of spectrum scanning, signal detection and radio noise measurement
- Package List: 1 x Frequency Counter (Built-in 4000mAh Battery, 4-inch Touchscreen); 1 x USB Charging Cable; 1 x T-Type Adapter; 2 x SMA Cables; 1 x GPS Antenna; 1 x 32GB Memory Card (Pre-installed); 1 x Wrist Strap with Touch Stylus; 1 x Extra Touch Stylus
