Basic settings for analog inputs/outputs:
●
All channels of the generator and analyzer are active; the unbalanced generator
output signal with minimum output impedance and maximum analyzer input impe-
dance are used.
●
All inputs/outputs are floating; the auto-range function is activated.
●
Frequency sweeps are usually performed logarithmically from 20 Hz to 20 kHz; the
appropriate graphical windows are open on the screen; the x-axis is scaled auto-
matically in the associated configuration panels; the y-axis is permanently set to
standard values.
●
Voltages are mostly given in volts; the generator output voltage is set to 0.1 V; dis-
tortion and intermodulation values are given in dB.
Basic settings for digital inputs/outputs:
●
Both channels are active; the generator generates 24-bit words; the analyzer ana-
lyzes 24 audio bits. The sampling frequency is set to 48
kHz, the Professional for-
mat acc. to AES 3 is used. The digital pulse amplitude of the generator is 1 V at the
BNC outputs, which corresponds to 4 V at the symmetric outputs.
●
Levels are mostly given in dBFS; audio signals are usually generated at a level of –
20
dBFS.
Users can, of course, adapt the used basic settings to their own specific measurement
tasks at any time. To do this, the respective setup must be loaded and the appropriate
changes are then made in the panels. The setup can then be saved again.
The application setups are also updated when new audio analyzer firmware is instal-
led. Modified setups should therefore be saved under a different file name.
Users are also free to create new directories for their customized setups.
