8.3.4 AGC Manual Gain
Function Command String Camera Response
Set AGC Manual Gain :AGN=[DDD]<cr> :o<cr>
Set the AGC manual gain value. [DDD] is the gain count value
with a range of 89-204. This is equivalent to a gain in dB from
32–5 dB.
Note that gain count and gain in dB are inversely related. A
gain code of 89=32dB, and a gain code of 204=5dB. Therefore
there are 4.26 counts/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.
Get AGC Manual Gain
:AGN?<cr> :oAGN[DDD]<cr>
Enquire the current AGC manual gain value. [DDD] is the gain
count value with a range of 89-204. This is equivalent to a
gain in dB from 32–5 dB.
Note that gain coount and gain in dB are inversely related. A
gain code of 89=32dB, and a gain code of 204=5dB. Therefore
there are 4.26 counts/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.
8.3.5 AGC/AEC Level
Function Command String Camera Response
Set AGC/AEC Level
:ALV=[DDD]<cr> :o<cr>
Set the AGC level. [DDD] is the level value with a range of 0-
255. For TM770 and TM773, the range is 80-773.
Get AGC/AEC Level
:ALV?<cr> :oALV[DDD]<cr>
Enquire current AGC level. [DDD] is the current value with a
range of 0-255. For TM770 and TM773, the range is 80-773.
8.3.6 ALC Mode
Function Command String Camera Response
Set ALC Mode
:ALM=[D]<cr> :o<cr>
Set the ALC (automatic level control) mode. [D] is the mode
parameter.
0 = Average.
1 = Log Average.
2 = Peak
Get ALC Mode
:ALM?<cr> :oALM[D]<cr>
Enquire current ALC Mode. [D] is the current mode value.
0 = Average
1 = Log Average
2 = Peak
