The section comprises the settings necessary to adjust the trigger for the switch
between the segments of a multi segment waveform. The parameters displayed
depend on the selected trigger source.
The parameters in this sections are identical with the parameters in the section "Next
Segment Trigger In" in the "Trigger/Marker" dialog; for detailed information see
"Next
Segment Trigger In" on page 382.
State (ARB)
Enables/disables ARB modulation.
Switching on this standard turns off all the other digital standards and digital modula-
tion types.
The output is based on the waveform file that is loaded. The name of the waveform file
is displayed next to "Load Waveform".
If a multi segment waveform is loaded the section "Multi Segment Waveform Options"
is indicated. In this section, the segment to be output is selected.
If no waveform file is loaded, ARB modulation cannot be powered up. "None" will be
displayed next to "Load Waveform". An error message asks the user to load a wave-
form file:
"No waveform file loaded. ARB MOD state remains off. Please select a waveform file
to load, before switching ARB MOD state on."
