Trigger

Field Two, lines 314 to 625

As the Field is changed, the appropriate value for Line is chosen to keep triggering on the same
line as before, or if this is not possible, the corresponding line in the new Field. For example,
suppose line 264 is selected while in the NTSC-M standard and the Entire Frame mode. This is
the first line in Field Two. If Field Two is then selected, the Line number changes to Line 1, the
same actual line in the TV signal. If Field One is then selected, the line number stays at 1, but
now we are triggering in the first line in Field One. The only exception to this is if we are on the
last line of Field One and change to Field Two. In this case, we go to the last line in Field Two.

Dependencies

This key only appears in Modes which support TV Trigger, otherwise the key is blanked.  If the
SCPI command is sent while the key is blanked, an error is returned.

Readback

This key displays the value read back from TV Line

Status Bits/OPC
dependencies

The Status Operation Register bit 5 "Waiting for Trigger" is set at the same time as the Sweeping
or Measuring bit is set. It is cleared when the trigger actually occurs (that is, after the trigger
event occurs and all the applicable trigger criteria have been met). A corresponding pop-up
message ("Waiting for trigger") is generated if no trigger signal appears after approximately 2
sec. This message goes away when a trigger signal appears.

Initial S/W Revision

Prior to A.02.00

TV Line

Selects the TV line number to trigger on. Line number range is dependent on the settings of the
Standard and Field menus within the TV trigger setup functions. When the line number is
incremented beyond the upper limit, the value will change to the lower limit and continue
incrementing from there. When the line number is decremented below the lower limit, the value
will change to the upper limit and continue decrementing from there.
