1.1 Introduction of BERTWave
The MP2100B BERTWave is a measuring instrument that combines the
functions of a pulse pattern generator (PPG), bit error detector (ED) and
sampling oscilloscope all-in-one instrument.
The PPG creates a digital signal with editable data transmission speed,
pulse voltage level, and send data pattern.
The ED compares the received data bit string with the expected data a bit
string and calculates the number of different bits (bit error count). It
calculates the bit error rate from the number of received bits and the bit
error account. The voltage level for recognizing 0 and 1 of the digital
signal, and the data bit string (pattern) can be edited.
The sampling oscilloscope displays the periodic signal waveform. An Eye
diagram can be displayed by summing the signal waveforms and signal
waveforms can be analyzed and mask tested.
