Title:
TESTER, DRIVER COMPARATOR CHIP, RESPONSE MEASURING DEVICE, CALIBRATION METHOD, AND CALIBRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/050607
Kind Code:
A1
Abstract:
A response measuring device (20) in which the output end of a driver (14) and the input
end of a comparator (16) are terminated at the earth potential through a transmission
path (30). The device (20) comprises a driver control section (32) for outputting
a first output waveform having a rising edge and a second output waveform having
a falling edge and a difference calculating section (38) for calculating the
difference between the response times according to the difference between a
first time from when a comparator (16) detects the rising edge of the first output
waveform until when the comparator (16) detects the falling edge of a first reflection
wave produced when the first output waveform is reflected by the termination
and a second time from when the comparator (16) detects the falling edge of the
second output waveform until when the comparator (16) detects the rising edge
of a second reflection waveform produced when the second output waveform is reflected
by the termination.
