Detailed description of PCB impedance tester:
Purpose: the characteristic impedance test system is designed with time domain reflection technology, which can test the characteristic impedance of PCB trace in batch, automatically, quickly and accurately, and provide functions such as test waveform analysis, statistical data analysis, automatic recording of test data, automatic issuance of test report and printing. It is applicable to the R & D, design, production and quality control units of circuit board manufacturers. It provides a fast, accurate, standard and economical solution for the characteristic impedance test of high frequency circuit board.

Solutions to common problems of PCB impedance tester
1. The numerical error is too high during the calibration.
Cause: caused by misoperation.
Solution: shut down for 1 hour, turn it on again for calibration.
2 software error is reported in single deletion.
Cause: operation is too fast.
Solution: you need to restart the software.
3 power on for 48 consecutive hours, and the log is not updated in time.
Cause: the machine will have self-protection function for a long time (no operation for more than 12 hours).
Solution: restart the software.
4 the horizontal resolution shows that part of the grid disappears.
Cause: the horizontal resolution adjustment is too small.
Solution: adjust the horizontal resolution to what you need.
