Error Handling and Recovery
— Point Mode trigger is not compatible with sweep setups that require
forward and reverse sweeps such as:
—Full 2port cal
—Cal ready (Full 2Port)
— Multiple displayed parameters that include the requirement for
forward and reverse sweeps such as S11 and S22 together on the
display
— When point mode trigger is already enabled, if conditions are changed
requiring forward and reverse sweeps, an error "Error: Point trigger
not compatible with 2-port cal." will be displayed and point mode
IMPORTANT!
If trigger signals come faster than the FieldFox can process them, some
triggers may be ignored or lost.
To ensure triggers are recognized and processed in order, use the external
trigger output function to indicate when the FieldFox is ready for another
input trigger. Alternatively, slow the external triggers coming in from
external equipment to a rate where FieldFox does not miss a trigger.
The External Trigger output signal is only selectable when Point Mode
Trigger is enabled. Not supported in other trigger modes.
External Trigger output signal is sent as soon as FieldFox has processed
the last trigger signal that was detected.
As each point is acquired, the data will show up on screen. If a trigger has
not been detected, a yellow Wait indicator will show on the sweep status
icon area.
