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.
