3.21. Signal Delay
With the system, you can set the signal delay time or pulse width for the various signals that are input
and output. Pulse width and delay settings for the various signals to input/output are made with PFV
or the remote controller (optional). The content of each setting is listed in the chart below.
Setting Item Setting Range (Value)
TRIG TTL IN DELAY 0-60 (s) 100 ns units
SYNC IN DELAY 0-1/frame rate (s) 100 ns units
GENERAL IN DELAY 0-60 (s) 100 ns units
TRIG OUT WIDTH 0-1 (ms) 100 ns units
SYNC OUT DELAY 0-1/frame rate (s) 100 ns units
SYNC OUT WIDTH 0-500 (us), 1/frame rate (s) at 2,000 fps or higher 100 ns units
EXPOSE OUT DELAY 0-1/frame rate (s) 100 ns units
SYNC OUT TIMES 0.5, 1, 2, 4, 6, 8, 10, 20, 30 (* x1 is standard output)
•
SYNC OUT TIMES
Values 1, 2, 4, 6, 8, 10. A value of 1 is normal output.
Set from the SYNC IN/OUT menu, SYNC OUT TIMES submenu.
Output a SYNC (vertical synchronization signal) from SYNC OUT that is 30 times SYNC.
Example: For a frame rate of 1,000 fps, SYNC OUT TIMES setting of 2.
Example: For a frame rate of 1,000 fps, SYNC OUT TIMES setting of 4.
•
An accurate frequency is output, but when SYNC OUT TIMES is set to a large value with a high
frame rate, the setting may result in frequency errors.
