AT3810A LCR Digital Bridge

CategoryBenchtop LCR Digital Bridge SeriesAT38XX Series

AT3810A features a true-color TFT-LCD display with a full Chinese operation interface (configurable to English). Large font display for more intuitive readings. Designed for laboratory quality control, incoming inspection, and component sorting. AT3810A offers continuous frequency points from 10Hz to 20kHz with a resolution of 0.001Hz. Test signal level: 0.01Vrms~2.00Vrms (10mV step). Compared to the AT28 series, it adds DCR measurement and internal DC bias (DC BIAS, ±2.5V).

AT3810A can test 4 parameters of components simultaneously, each parameter can be freely configured. The newly improved instrument achieves full 6-digit display for all four primary and secondary parameters. It can scan 10 frequencies or level lists, and allows calibration of 3 user-defined frequencies for improved accuracy. Built-in comparator for automatic component sorting via HANDLER interface combined with PLC.

The instrument comes standard with RS232, RS485, and USB interfaces, supports SCPI and Modbus protocols, and can be optionally equipped with a GPIB interface.
