Coupling. Coupling allows you to filter the trigger signal used to
trigger an acquisit ion.
Option Details
DC Passes all components of the signal
Noise Reject Adds hysteresis to the trigger circuitry; this reduces sensitivity
which reduces the chance of falsely triggering on noise
HF Reject Attenuates the high-frequency components above 80 kHz
LF Reject Blocks the DC component and attenuates the low-frequency
components below 300 kHz
AC Blocks DC components and attenuates signals below 10 Hz
NOTE. Trigger coupling affects only the signal passed to the trigger
system. It does not af fect the bandwidth or coupling of the signal
displayed on the screen.
Pretrigger. The trigger position is typically set at the horizontal center
of the screen. In t his case, you are able to view five divisions of
pretrigger information. Adjusting the Horizontal Position of the
waveform allows you to see more or less pretrigger information.
