LAGCMIN is set to -10, then the AGC for that channel can apply a minimum of -10 dB of gain to the input signal.

This command was introduced in firmware version 2.5.0.

This command is a channel integer command. See Section 6.3 and Section 6.2 for more information

on this type of command. The minimum and maximum values for this command are -15 and 0, respectively.

This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.

Example

S01LAGCMINA-3

S01LAGCMINB?

Description

Set AGC minimum gain on input channel A to -3 dB.

Query the AGC minimum gain on input channel B.

Status Message

S01LAGCMINA-3

S01LAGCMINBx , where x is a number between -15 and 0, depending on the current setting of the AGC minimum gain on input channel B.

8.72. LAGCRATE -- Set Ramp Rate of Line Input AGC

This command sets or queries the maximum rate at which the AGC can increase or decrease the gain of the signals on input channels A-B. The ramp rate is expressed in dB/sec.

This command was introduced in firmware version 2.5.0.

This command is a channel integer command. See Section 6.3 and Section 6.2 for more information

on this type of command. The minimum and maximum values for this command are 1 and 5, respectively.

This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.

Example Description

Set AGC ramp rate on input

S01LAGCRATEA3 channel A to 3 dB/sec.

Query the AGC ramp rate on input S01LAGCRATEB? channel B.

Status Message

S01LAGCRATEA3

S01LAGCRATEBx , where x is a number between 1 and 5, depending on the current setting of the AGC ramp rate on input channel B.
