10 Hz to 20 kHz Expected frequency of the audio input signal 100 Hz V3.0
Description of command
This command is to reduce the measurement time the audio analyzer uses to calculate the measurement results
(<Mode>=EXPF); see section Subsystem AFANalyzer... (Measured Values) on page 6.73. The measurement
time must be adapted to the period of the input signal, which is the reverse of the frequency. Therefore, the audio
measurement can be accelerated for high-frequency signals. In the LOWF mode, <Frequency> is not taken into
account.
Subsystem AFANalyzer...:CONTrol (Control)
The subsystem AFANalyzer:...CONTrol defines the scope of the audio analysis and sets the reference
frequency for the distortion measurement. The settings are provided in the Control and Distortion tabs
of the Analyzer Configuration popup menu.

Description of command
This command determines the number of statistics cycles and the stepping mode for the measurement. A stop
condition is not available.
Note: In the case of READ commands (READ: to) the <Repetition> parameter has no effect; the measure-
ment is always stopped after a single shot.
