Example 6: Configuring the digital generator DSI output settings
In this example, you will learn how to configure the U8903B digital generator DSI output
settings.
To configure the digital generator DSI output settings to DSP format, sampling rate of
192 kHz, word length of 24, and multiplier of 192, perform the following steps.
1 Press on the FUNCTION panel to switch to audio generator mode, and press
on the FUNCTION panel to switch to digital interface.
2 Press DSI Config > Format , and select DSP as the DSI output format.
3 Press DSI Config > Sample Rate , and set the sampling rate to 192 kHz .
4 Press DSI Config > Word Length , and set the DSI word length to 24 .
[1][2]
5 Press DSI Config > Multiplier , and set the DSI multiplier to 192 .

[1] Sampling rate constrains the DSI word length values. Refer to “ Appendix 24: Word Length, Sampling
Rate, and Multiplier for DSI ” on page 583 for the range of word length that can be set with different
sampling rate.
[2] When setting the word length, the error message, –221,“Settings conflict...” may be generated. This error
message can be ignored as this is to notify that the word length or multiplier is auto adjusted to the
nearest allowable value due to the settings conflict.
[3] Sampling rate and word length constrain the multiplier values. Refer to “ Appendix 24: Word Length,
Sampling Rate, and Multiplier for DSI ” on page 583 for the range of multiplier that can be set with
different DSI word length and sampling rate.
