AGC Mode
Function
Command String
Camera Response
Set AGC Mode
:AMD=[D]<cr> :o<cr>
Set the AGC mode. [D] is the mode parameter.
0 = Manual.
1 = Auto.
User access to control of the AGC feature is determined by the
SB1 setting. If “AMD=: is received, but SB1=0 the command has
no effect, but does not return an error code. Note: If AEC is
set to auto, the AGC mode is forced to manual.
Get AGC Mode
:AMD?<cr> :oAMD[D]<cr>
Enquire current AGC Mode. [D] is the current mode value.
0 = Manual.
1 = Auto.
User access to control of the AGC feature is determined by the
SB1 setting. The “AMD=?” command returns the current value
regardless of the SB1 value.
8.3.8
AGC Max
Function
Command String
Camera Response
Set AGC Max
:AMX=[DDD]<cr> :o<cr>
Set the AGC max value. [DDD] is the gain code value with a
range of 25-178. This is equivalent to a gain in dB from 32–18
dB.
Note that gain code and gain in dB are inversely related. A
gain code of 25=32dB, and a gain code of 178=5dB. Therefore
there are 10.93 count/dB.
For the TM770C color camera, the gain count value has a range
of 0-1023 which corresponds to a gain in dB from 0 – 36 dB.
The count and gain are not inversely related.
Get AGC Max
:AMX?<cr> :oAMX[DDD]<cr>
Enquire current AGC max. [DDD] is the gain code value with a
range of 25-178. This is equivalent to a gain in dB from 32–18
dB.
Note that gain code and gain in dB are inversely related. A
gain code of 25=32dB, and a gain code of 178=5dB. .
Therefore there are 10.93 count/dB.
For the TM770C color camera, the gain count value has a range
of 0-1025 which corresponds to a gain in dB from 0 – 36 dB.
The count and gain are not inversely related.
