3.5 Small Tiger Gain & Offset Control Panel
(T8810/T8820 Gain & Offset Control Panel will be added in future)
Tiger cameras provide independent analog gain and offset control over each tap output.
Use the Gain & Offset screen to control the digital gain parameters, digital offset
parameters, and tap balance.
Figure 43: The Gain & Offset screen provides analog and digital gain.
Analog Gain
. Analog gain amplifies the image signal before converting the signal to digital
data. You can set the analog gain from 0 to 36 dB and shift the signal using offset from 0
to 25% of dynamic range in 4095 steps.
Select the Link Gain check box to link all analog gain controls for the four output taps
together so that changing one analog gain parameter changes all analog gain parameters
to the same value. The Link Offset check box provides the same linking capability for
Offset parameters.
Digital Gain
. You can set the digital gain from 1.0x to 4.0x in 0.001x-step changes and
digital offset from +/- 12.5% of dynamic range in 1024 steps (-512 to +511 in 1-step
increment).
Corrections
. Tap balance correction uses algorithms implemented in the firmware to
correct misbalances that might occur between the
camera’s separate output
video signals.
It compares the values between the adjacent taps and adjusts the corresponding tap gains
to equalize the average values. In multi-tap cameras, tap balance helps ensure a uniform
image.
From the Gain & Offset screen, click the Correction Tap Balance drop-down and select the
following:
•
Off
. Turns off tap balance.
•
Auto
. Balances tap outputs continuously.
•
Once
. Balances tap outputs once.
3.6 Output Control Panel
The Output Control panel lets you map camera output signals to strobes and control the
internal pulse generator settings (if available).
