Audio Bits
If the word width is decreased, the values of the audio samples are rounded to the
specified word width. Unused data bits are encoded as zeroes in the digital audio sig-
nal.
Value range: 8 ... 24

Sample Frequency
Used to set the clock rate of the digital audio signal for the generator.
The sample frequency setting is used as a reference whenever audio data signals are
generated.
The selected clock rate determines the maximum signal frequency which can be input.
For sine-wave signals, it is 49.9
% of the sampling rate.
If the sample frequency entered does not match the actual clock rate (e.g. with external
synchronization), all audio data signals shift accordingly in frequency.
This setting is also used to select the correct range for the Sync PLL.
Value range for numeric input:
30 kHz ... 200 kHz
Standard sampling frequencies can be set directly in the selection field.
Synchronization ranges for the generator sync PLL:
Base rate range 30 kHz ... 64 kHz
High rate range 65 kHz ... 128 kHz
Extended rate range 129 kHz ... 200 kHz
"32 ...192 kHz" Standard sampling rate 32 kHz ... 192 kHz
"Value " Variable input of sampling rate
