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
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 “
Sampling Rate, and Multiplier for DSI
for the range of multiplier that can be set with
different DSI word length and sampling rate.
