3.4.2 Setting the Frame Rate
Purpose:
Sets the camera’s frame rate in frames per second (Hz).
Syntax:
ssf f
Syntax Elements:
f
Set the frame rate in Hz in a range from
1-60.4
(4M60 full
frame, 80 MHz cameralink strobe, efd 1) or
1
-
30.6
(4M30 full
frame, 80 MHz cameralink strobe, efd 1). Range increases
when using a vertical window of interest.
Notes:
•
Camera must be operating in exposure mode 2.
•
Allowable range is dependent on the current Camera Link
mode, snapshot mode, number of fast frame dumps and
window size. Refer to section above for more information on
Camera Link modes. Refer to section 3.5 for more information
on setting a window size.
•
Changing the frame rate will automatically adjust the
exposure time if necessary. The camera sends a warning when
this occurs.
•
Refer to section 3.3.3 Setting the for more information on how
to set the cameralink strobe.
•
When in SEM 2, the help screen (h) will shown the limits for

3.4.3 Setting the Exposure Time
Purpose:
Sets the camera’s exposure time in µs.
Syntax:
set f
Syntax Elements:
f
Floating point number in µs. Allowable range is 10-999989 µs.
The following table lists allowable increments.
Notes:
•
Camera must be operating in exposure mode 2.
•
To retrieve the current exposure time, use the command
gcp
.
•
If you enter an exposure time outside of a valid range, the input
will not be accepted. Refer to the help screen (
h
command) for
the valid range.
•
If you enter an exposure time which overlaps with the frame
readout, the exposure time will automatically adjust to integral
units of exposure time increments (only in sem 2). The camera
adjusts the exposure without warning. Refer to Allowable
Exposure Time Increments.
•
Changing the exposure time will automatically adjust the frame
rate if necessary. The camera sends a warning when this occurs.
