Single/Cont
This field specifies how long you want the analyzer to decode incoming
signals:
• Single tells the analyzer to display the information received during
one Gate Time. Measurements are displayed until Arm Meas is
selected again.
• Cont is used to automatically re-arm the analyzer and display the
measurements on a continual basis until Single is selected.
Previous measurement results are over-written by subsequent
measurements.
Operating Considerations
To dis-arm the decoder in single mode, select the Stop Meas field. The
Stop Meas function is disabled when Cont is selected.
