Operation
except you also need to set a power threshold to avoid triggering on the apparent frequency fluctuations that occur at low
amplitude. You
can select the time-domain bandwidth and trigger on the rising or falling edge.
Frequency Mask Triggering. Frequency Mask Triggering allows you to trigger the instrument when a signal in the
frequency domain violates the mask. You can draw a mask to define the conditions within the r eal-time bandwidth that will
generate the trigger event. It allows you to trigger on weak signals in the presence of strong signals. This triggering is
also useful for capturing intermittent signals.
Power Trigge
ring.
Power triggering triggers the instrument on time-domain signal characteristics. The incoming data is
compared to a user-selected level in dBm. You can select the time-domain bandwidth and trigger on the rising or falling edge.
In addition to defining the trigger event, you can define the following parameters by selecting the appropriate tab in
the Trigger control panel:
Position and Delay parameters that define where a trigger occurs within the acquired data record and whether to
delay the t
rigger for a set amount of time.
Whether a s
ingle event can trigger an entire sweep, or each segment of the sweep requires a new trigger event in
swept acquisition mode.
