AM700 Audio Measurement Set Service Manual
4–37
12. Set DUT as follows:
Set Long Cable Simulation = OFF
13. Connect the DUT to the test AM700 as follows:
DUT Digital Out signal to the test AM700 Digital In connector
DUT AES REF OUT to the test AM700 AES REF IN connector
14. Touch the Interface Timing soft key, and then touch the Clock Phase Offset
soft key. Press the Units button until the units are set to UI.
15. Set the DUT Clock Phase Offset to: –1, +1, –64, and +63.5. Check that the
test AM700 Phase Diff. reads the same as the DUT. (Note that –64 yields
+64.)
1. Connect the DUT the the test AM700 as follows:
DUT Digital Out to the test AM700 Digital in
Test AM700 AES REF OUT to DUT AES REF IN
2. Set the DUT as follows:
Touch Interface Timing soft key
Select Mode = From Ref
3. Set the test AM700 as follows:
Mode = From Audio
4. Check that the test AM700 has a Peak to Peak Jitter reading of 0.08 UIp-p
or less. If reading is >0.09, check again with the test AM700 sample rate
at 44.1 kHz.
1. Connect DUT AES REF OUT to the test AM700 Digital In.
Set DUT: Mode = From Audio
2. Check that the test AM700 Peak to Peak Jitter reading is 0.03 UIp-p or less.
3. Set DUT:
Mode = Variable
Var Freq = 52 kHz
4. Check that the test AM700 Peak to Peak Jitter reading is 0.08 UIp-p or less.
Check Main Output
Residual Jitter
Ref Output Residual Jitter
