Line
It is synchronized with AC power frequency, it will start sweep. Line trigger is
conveniently used when observing waves related to power.
TRIG >> Line
■
External Pos Neg
It is synchronized with external trigger source, thus, it will start sweep. The sweep
starts from the ascending/descending angle of the signal wave form inputted on
EXT TRIG input connector of the back panel. To start the trigger, TTL input signal is
required.
TRIG >> External
■
Trig Delay On Off
You can set the delay of the time that the analyzer is awaiting, or turn it on or off
before starting sweep after receiving the external trigger signal. This function can
be used only when it is an external trigger.
TRIG >> Trig Delay
5-22. Trace
Allows the user to manipulate and save trace information displayed on the LCD screen. The
spectrum analyzer renews the trace information after every sweep.
■
Trace 1 2 3
To select a trace, press the softkey Trace 1 2 3 until the number of the desired
trace is underlined.
TRACE >> Trace
■
Clear Write
It deletes data previously saved in trace memory. It saves amplitude data newly
acquired after sweeping, and indicates the amplitude data on display LCD screen.
This function is applied to trace 1 when inputting power.
