Example 5: Configuring the system clock reference settings

In this example, you will learn how to configure the U8903B system clock reference
settings.
To configure the system clock reference source to external Master clock in with word length
of 24 and multiplier of 192, perform the following steps.
1 Connect the external Master clock signal to the Sync In connector in the rear panel
using a BNC cable.
2 Press
3 Press Output Config > Ref Clock > Source, and select External as the reference clock source.
4 Press Output Config > Ref Clock > Type, and select MCLK to set the external clock source
type as Master clock.
5 Press Output Config > Ref Clock > Word Length, and set the Master clock word length to
24.
6 Press Output Config > Ref Clock > Mul tiplier, and set the Master clock multiplier to 192.
[1] Sampling rate constrains the master clock in word length values. Refer to "Append ix 25: Word Length,
Sampling Rate, and Multiplier for Master Clock In" on page
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 "Append ix 25: Word Length,
Sampling Rate, and Multiplier for Master Clock In" on page
set with different master clock in word length and sampling rate.
