CPC G01R 31/3177 (2013.01) [G01R 31/31703 (2013.01); G06F 11/10 (2013.01); H04L 25/4917 (2013.01)] | 8 Claims |
1. An error rate measuring apparatus that inputs a Non Return to Zero (NRZ) signal of a known pattern as a test signal to a device under test, receives a signal from the device under test with the input of the test signal, and measures whether or not a forward error correction (FEC) operation of the device under test is possible based on a comparison result of the signal received from the device under test and the test signal, the error rate measuring apparatus comprising:
a processor configured to:
set a codeword length and an FEC symbol length of the FEC corresponding to a communication standard of the device under test; and
compare bit string data obtained by converting the signal received from the device under test with error data to detect an FEC symbol error of each FEC symbol length; and
a display configured to, based on a detection result of the FEC symbol error, associate the bit string data of the FEC symbol length as one point with one unit region of a display region of the display, and perform color-coding display on the display depending on presence or absence of occurrence of the FEC symbol error by each FEC symbol length.
