ZY3690 Type Impedance Filter Combined with Filter Automatic Tester is an intelligent and fully digital instrument that adopts advanced international technologies such as vector detection, logarithmic compression, and digital direct synthesis (DDS). It has the characteristics of fast, accurate, and easy operation, and is suitable for measuring the high-frequency characteristics of impedance filters and combined filters.
The ZY3690 is a block wave combiner filter that offers fully digital operation, a high‑resolution LCD display, and vector synthesis (DDS) for precise impedance and loss measurements. It supports a wide frequency range, multiple capacitor options, and RS‑232C communication for data logging and PC control.
This manual describes the device’s dimensions, performance specifications, panel layout, step‑by‑step usage, and general fault handling. It also includes calibration procedures, RS‑232C settings, and safety guidelines for field measurements. This manual is written in Chinese.
