The bulk attenuation switch out threshold is forced to match the switch in threshold when the AGC is in IF mode.
This is to prevent the AGC from attempting to switch the bulk attenuator while using a path that doesn't have a bulk
attenuator.
AGC [BA [<e>|V <a>|D <t>|{I|O <t> [A]}]]
- AGC bulk attenuation settings
<e> - Sets bulk attenuation control enable to <e>
where: <e> - Enable
0 - Disabled, switched out
1 - Enabled, switched in
A - AGC control enabled
V <a> - Attenuation value to <a>, 0.0000 to 511.9375 dB
D <t> - Switch out threshold delta attenuation <t>, -255.5 to -0.0 dB
I|O <t> - Switch In|Out threshold at input power <t>, in dBm
I|O <t> A - Switch In|Out threshold at attenuation <t>, 0.0 to 255.5 dB
Examples:
AGC BA 1
Bulk attenuator AGC control enabled, switched in
AGC BA V 17.000
Set attenuation value to 17.000 dB
Valid range 0.0000 to 511.9375 dB
AGC BA D 33.3
Set switch out threshold delta attenuation to -33.3 dB
Valid range -255.5 to -0.0 dB
AGC BA I x
Set switch in threshold at input power to x dBm
AGC BA O x
Set switch out threshold at input power to x dBm
4.3.2.4.2 Automatic Gain Control Data Settings - AGC DATA
The AGC DATA command is used to set the AGC table attenuation value for a specific attenuator along with an
attenuation or data operation value. Parameter values are explained below.
AGC DATA [<p> <a> = <v>|<o>]
- AGC data settings
<p> <a> = <v> - Set AGC table attenuation <p>, attenuator <a> to attenuation <v> dB
where:
<p> - 0.0 to 255.5 dB
<a> - Attenuator A, B, C, D, E
<v> - Attenuation 0.0 to 31.5 dB or 'MIN' or 'MAX'
<o> - Data operation
LOAD - Load data
ERASE - Erase data
