XL-805 Combined Unit Tester
The combined unit tester series products are designed according to standards such as "DL/T 1943-2018 On-site Inspection Specification for Combined Units". They are mainly used for laboratory and field testing of combined units based on analog input, digital input, non-traditional small signal input, and mixed input.
Product Description
Features
- Comprehensive test items: Supports test items including basic error, frame transmission delay, frame release discrete value, timing and holdover, resynchronization after slip, frame integrity, harmonic influence, frequency influence, harmonic measurement accuracy, etc.
- Multiple synchronization methods: Supports IRIG-B code, 1PPS synchronization signal output/input, and asynchronous delay methods to verify the accuracy of analog input merging units; synchronization signals support optical and electrical signals.
- Wide adaptability: Built-in three-phase standard voltage and current sources and high-precision AD sampling modules enable offline calibration of analog input merging units. The signal source supports superimposed multiple harmonic outputs for comprehensive testing of various accuracy indicators of merging units.
- Precise extended functions: Supports protocol testing, full frame analysis, multi-channel testing, harmonic analysis, harmonic verification, transient recording, FT3 anomaly testing, SCD file parsing, and other functions and troubleshooting methods.
- Integrated design: Integrates three-phase standard voltage and current sources, high-precision AD sampling, synchronization module, digital message parsing module, precision small signal source, and precision FT3 digital source in one unit, eliminating the need for various external modules. The integrated design ensures comprehensive and reliable performance.
- Powerful professional software: Can display standard and actual waveforms during testing, calibration points, effective values of standard and tested signals, signal frequency, harmonic bar charts, and distortion rate; can also statistically analyze mean difference angle, variation, extreme values, etc.
- Good human-machine interaction: Equipped with a large touch display screen, clear and intuitive value display, and multiple interfaces including RJ45, RS232, and USB, facilitating the construction of automated testing systems.
