scope
The scope shows the waveform of the input signal. It measures the
• dominating fundamental frequency
• momentary peak level
and adjusts the X and Y-axis scaling automatically.
Y-Axis scale: Automatic scaling from 25%/div to 0.1ppm/div (allowing
to see the LSB of a 24 bit signal).
Actual level peak: Since it is sometimes difficult to get a feeling for
values of e.g. 0.6 ppm, the actual peak level of the data shown on
the screen is displayed in dBF.
X-Axis scale: Automatic scaling from 1 to 500 samples per
division.
pause: The scope display may be paused by selecting this field with
the cursor and pressing the enter key.
Fundamental frequency: The input signals that fundamental or most
dominant frequency are displayed.
NOTE The scaling of the SCOPE display cannot be changed
manually.
