•From Sensitivity select Normal for normal input sensitivity, or High for
increased input sensitivity (<1 µV) to locate low level signals. Sensitivity
also is used to set the vertical scale (dB/Div).
NOTE: Using High Sensitivity may cause erroneous amplitude or AM side-band
amplitude measurements.
•From Normalize
select Save B to save the current trace (can only be performed when
A Only is selected).
select to display a continuously updated screen (normal operation).
