Title:
TESTING APPARATUS, ADJUSTING APPARATUS, ADJUSTING METHOD AND ADJUSTING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2007/072738
Kind Code:
A1
Abstract:
A testing apparatus for testing a device to be tested is provided with a plurality
of signal inputting/outputting sections each of which has a signal outputting
section and a signal inputting section. In each signal inputting/outputting
section, a phase difference between output of the signal by the signal outputting
section and input of the signal by the signal inputting section is adjusted to
be substantially equal to that of other signal inputting/outputting sections.
Then, in a status where the signal inputting/outputting sections are connected
with each other, a shift quantity by which signal inputting timing is to be shifted
for permitting the second signal inputting section to input the signal outputted
by the first signal outputting section is detected. A shift quantity by which
the signal input timing is to be shifted for permitting the first signal inputting
section to input the signal outputted from the second signal outputting section
is also detected. Based on such shift quantities, the phases of the signal input
and output of the first and the second signal inputting/outputting sections
are adjusted to be substantially the same.
