Test method
• Warm up the TA120E and FG300 for 30 minutes before the test.
• Set the frequency of the FG300 to 180.18 kHz and set the polarity of the data
signal and the trigger mode of the TA120E according to the table below. Confirm
that the standard deviation
σ
(jitter) under the 3T jitter measurement is within the
allowable range in the table below. The average value is reference value.
Test procedure
1.
Load the arbitrary waveform data SLICE.WVF into the FG300. Set the output
frequency to 180.18 kHz, the output voltage amplitude to 6 V
P-P
, the phase to
0.0 deg, the offset voltage to 0.0 V, and the output attenuator to 1/10.
2.
Set the polarity of the data signal of the TA120E to
and the trigger mode to
[MAN].
3.
Set the TA120E in the statistical value debug mode, and read the standard
deviation
σ
. Confirm that the value is within the allowable range. The average
value is reference value.
4.
Set the polarity of the data signal and the trigger mode of the TA120E according
to the table below, then perform the test in a similar fashion.
