AGC Status Tile

The AGC tile displays the Automatic Gain Control (AGC) data for the G-III Reference Receiver.

The AGC data for a single DSPC card is displayed on the tile. To view the AGC information for another DSPC, click the button for the DSPC card to view. For example, to view the AGC data for DSPC2, click the DSPC2 button.

To view additional AGC information, click the View Frequency Information link. A text box appears below the AGC graph with the following information.

AGC Word

The AGC status word.

Pulse Width

The VARF pulse width.

Modulus

The VARF modulus.

Noise Floor

The calculated noise floor.

% Pulses Blanked

The ratio of samples blanked over the previous second.

DC Offset

The A/D DC offset estimate (samples).

Active Flag

Indicates if the card is controlling the AGC for this frequency.

Bin Skew

Indicates if Bin Skew is present.

AGC Calibration

Indicates whether AGC calibration is Coarse or Fine.

ADC Range

Indicates which 3 bits of the 8-bit ADC output are currently being used by the receiver.

Noise Floor Calculation Method

Indicates whether the method of Noise Floor Calculation is AGC or Post Correlation.

Bin Count Overflow

A flag identifying when more than 1 bin was filled with 1023+ samples.

Rail Gain

A flag identifying when the VGA is railed high/low for 3+ consecutive seconds.

Bins Not Full

A flag identifying when all the bins contain 1 or more but less than 1023 samples.

Bins Empty

A flag identifying when all the bins are empty.

AGC Status Tile Indicator
Indicator Color	Status
Red	Either one of these conditions is met: AGC Pulse Width = 0 or 1000 Railed Gain = 1 The status indicator will be red if any of the RF paths meet one of the above conditions.
Amber	The conditions to be red are not met and one of these conditions is met: AGC Pulse Width is > 900 or AGC Pulse Width < 100 Bin Skew = 1 Bins Not Full = 1 Bins Empty = 1 The status indicator will be amber if none of the RF paths meet the criteria to be Red and at least one of the RF paths meet one of the conditions above.
Green	All of the following conditions are met: AGC Pulse Width <= 900 or AGC Pulse Width >= 100 Bin Skew = 0 Railed Gain = 0 Bins Not Full = 0 Bins Empty = 0 The status indicator will be green only if all of the available RF paths meet the above conditions.
