Test method
• Test the TA120E after 30 minutes of warm-up.
• Set the frequency of the 8657B to the values indicated in the table below and
confirm that the standard deviation
σ
(jitter) and the average value under the 3T
jitter measurement of the TA120E are within the allowable range in the table.
Test procedure
1.
Set the output level of the 8657B to 35 mVrms and the frequency to 720 kHz.
2.
Set the speed of the TA120E to [1.0].
3.
Read the standard deviation
σ
and the average value. Confirm that the values
are within the allowable range.
4.
Set the output level and frequency of the 8657B and the speed of the TA120E
according to the table below, then perform the test in a similar fashion.
