Adjustment of Stereo Coder Module
The analog audio signal path gain and offset can be adjusted by performing the internal adjustment
(Setup/Internal Adjustment/Adjust All).
For adjustment of the digital audio signal path, an additional S/P DIF source is required:
Important: Allow the DUT to warm up for at least 20 minutes before adjustment is executed

Internal Self Test
After each module replacement, it is recommended to perform the internal self test (refer to chapter 3,
“Troubleshooting with Internal Self Test”). The self test checks the instrument by measuring internal
diagnostic points and verifies whether generator is operating properly.
If a self test failure occurs, check again whether all cables are properly connected. If the self test fails
continuously, contact your local service center.
