4.7.4

Setting the Frame Rate

To set the camera frame rate, the camera must be operating in exposure mode 2.
Changing the frame rate will automatically adjust the exposure time if necessary. The
camera sends a warning when this occurs.

Refer to section 4.6.2 Setting the Camera’s Pixel Rate

on page 33

for more information on

how to set the camera’s pixel rate

Allowable range is dependent on the current Camera Link mode and window size. Refer
to section 4.6.1 How to Configure Camera Output

on page 31

for more information on

Camera Link modes and section 4.8 Setting a Vertical Window of Interest

on page 42

for

more information on setting a window size.

Serial Command

Purpose:

Sets the camera’s frame rate in Hz.

Syntax:

ssf

Syntax Elements:

Set the frame rate in Hz in a range from

0.1-101.9

(full

frame, 80 MHz pixel rate) or

0.1-51.1

(full frame, 40 MHz

pixel rate). Range increases when using a window of interest.

Related Commands:

sem, set

Example:

ssf 25.0

CamExpert Parameter

The frame rate can be specified using the Frame Rate (Hz) parameter available through
the Camera Control tab.

Falcon Frame Rate (Hz) – on Camera Control Tab
