State
Enables/disables ARB modulation. Switching on the ARB generator turns off all the
other digital standards and digital modulation types in the same signal path.
The output is based on the waveform file that is loaded. The name of the waveform file
is displayed next to "Load Waveform". When a multi-segment waveform is loaded, the
display expands and lists more settings, grouped in the "Multi Segment Waveform
Options" section.
Note: ARB generator cannot be activated.
You cannot activate the ARB generator in the following cases:
●
No or empty waveform file
If no waveform file is loaded, as in the default state, "None" is displayed next to
"Load Waveform". An error message indicates that no or empty waveform file is
selected.
Select a waveform file, before switching on the ARB.
●
Missing burst gate marker in the waveform but "RF Power Ramping with Burst
Gate Marker > On"
If "RF Power Ramping with Burst Gate Marker > On" but the loaded ARB waveform
does not contain control list or the burst gate marker is not defined, the ARB gener-
ator cannot be activated.
An error message indicates this situation, too.
