Test method
• Warm up the TA120E and FG300 for 30 minutes before the test.
• Set the frequency of the FG300 to 74.04665 kHz and confirm that the standard
deviation
σ
(jitter) under the D-to-C jitter measurement of the TA120E is within the
allowable range in the table. The average value is reference value.
Test procedure
1.
Load the arbitrary waveform data PLL.WVF into the FG300. Set the output
frequency to 74.04665 kHz, the output voltage amplitude to 0.3 V
P-P
, the phase
to 0.0 deg, the offset voltage to 0.0 V, and the output attenuator to 1/1.
2.
Turn ON the PLL of the TA120E.
3.
Set the TA120E in the statistical value debug mode, and read the standard
deviation
σ
. Confirm that they are within the allowable range. The average
value is reference value.
