Scanner Parameters
Automatic Gain Control
AGC Sampling Mode
Disabled (Fixed Gain)
When AGC Sampling Mode is Disabled, the first parameter in the Gain Level command
defines the Fixed Gain used to amplify the analog signal. In most applications, when
changing the sampling mode to Disabled, the Gain Level will need to be changed. For
Fixed Gain operation, changes to gain adjustment settings can be performed in
Auto Calibration
.
Leading Edge
Leading Edge
uses only the first signal sample to calculate gain adjustments. The
Transition
Counter value is used to determine which transition triggers the sample.
Important: This option should only be used if recommended by a Microscan Sales or
Applications representative, as the other AGC modes cover most application requirements.
Continuous
Continuous will take the highest value among any samples within a scan and use that
value to make adjustments.
