The sampling frequency corresponds to the frequency of the FSYNC signal. All fre-
quency information of measured audio data relates to this setting.
If the selected frequency does not correspond to the applied frequency, all filters and
frequency measurements are shifted accordingly with respect to frequency.
Standard sampling frequencies can be set directly in the selection field.
"Auto" The sampling rate is measured, set and displayed in the following
line. If the applied sampling rate is changed the set value is automati-
cally updated.
Note: The digital analyzer must re-initialized for each new sampling
frequency. To avoid the need to repeat this time-consuming proce-
dure too often, minor deviations and fluctuations (below 3
Hz) are
ignored.
"8 kHz to
192 kHz" Standard sampling rates 8 kHz ... 192 kHz
"Value:" Variable input of sampling rate
Value range for numeric input: 6.75
kHz to 200 kHz
