Product Details
✓TinyGTC ZC412: A dual Timer/Counter frequency counter blending ultra-precision, portability, and advanced functionality—engineered for accurate measurements. Complemented by a 4" touchscreen, physical buttons, and USB remote operation. Data handling is effortless with a micro SD card slot (up to 32GB) for storage and USB for readout, streamlining workflows. Built for mobility with a 4000mAh Li-ion battery (USB 5V 1.3A max charging)
✓Ultra-High Precision Measurement: The counter boasts 40ps time resolution (4ns for GPS PPS counting) and dual independent high-resolution counter/timers, enabling gapless measurements of frequency, time, phase, and count (no limit on inter-event time). It covers up to 12GHz frequency range with 12 digits/s frequency resolution. Measurement intervals for frequency/phase/count are adjustable from 10ms to 10s
✓Advanced GPS Integration: Equipped with a built-in GPSDO, it locks to GPS to sync the internal clock with UTC time, guaranteeing high long-term accuracy. Time measurements can be relative to the device's start time or linked to UTC (when GPS-locked), enhancing reliability for time-critical tasks
✓Reliable ADEV & Versatile Analysis: Unique gapless interval measurement delivers reliable ADEV results. Measurement data is displayed flexibly via 5 numeric rows (with selectable formats) and graph modes (vs. time, up to 400 measurements), plus advanced transforms (histogram, linear residue, ADEV) for in-depth analysis. Accumulated data (up to 3000 measurements) can be output via USB or stored on an SD card
✓Robust Hardware & Precision Engineering: Features three counter/timer sources (A Input, B Input, REF Input/Output) and an internal 4ns-resolution counter for GPS PPS. Core hardware ensures gapless event counting (no count loss) and precise event timing. High-precision storage & calculation (10ps time units, 64-bit processing, ≥17 significant digits) supports versatile parameter derivation (frequency, time, phase, count) and flexible short/negative time difference measurements
✓Battery-Powered & Complete Package: As a battery-powered handheld unit, it features a 4000mAh capacity, combining professional-grade functionality with convenient mobile operation for on-the-go use. The tinyGTC ZC412 comes equipped with essential accessories: a 32 GB micro SD card, a USB cable, an SMA Tee, 2 short SMA cables, and an active GPS antenna
