XenICs XEVA XC-130 Camera Operation

This section describes the camera controls that are unique to the XenICs XEVA XC-130 camera. Common
controls are covered in other sections of this manual.
D.3.3.1 Exposure|Gain|Black Level
D.3.3.2 Camera Correction File
The following settings are preset in the TrueNUC or NUC
file to optimize the camera dynamic range for best beam
measurement accuracy. Only the Exposure setting can
be altered by the user. The Exposure setting is saved in
a BeamSquared setup file.
The Exposure control operates much like any other type
of camera. It sets the exposure duration in milliseconds.
When operating in external trigger mode, the exposure
time begins upon receipt of the electronic trigger pulse.
When using a regular NUC file (not a TrueNUC) the
exposure setting should not be changed.
The Gain setting, ADC Vref, and ADC Vin indicators are
preset to the value that corresponds to the TrueNUC/NUC
file. Displayed here for verification purposes only.
To successfully use an InGaAs camera, such as the XC-130, a
camera correction file must be applied. The file must match how
the camera is setup for use. When the Xeneth software is
installed it copies the camera correction NUC files into a folder
called:
C:\Program files\Xeneth\CalibrationPacks\...
This folder contains 2 or more .xca NUC files specific to each
camera's serial number. The name of the file gives details about
when it should be applied. A file that contains the letters LG or
HG are for low gain/high gain settings respectively.
To load a NUC file click on Ellipses, and then browse to the
CalibrationPacks folder shown above. Select the appropriate
TrueNUC/NUC .xca file and click Open.
The Two Point Correction box should always be checked to
operate with the NUC table applied. If unchecked you can
observe what the camera output looks like without NUC.
This file name is saved in a setup file and automatically applied
to the camera upon opening the setup if the camera is already
attached. If the camera was not connected then you may need
to manually restore it.
