3.4.19 Alternate Correction Table
This command allows the user to select either the standard or the alternate Offset and Gain
Correction tables. The standard tables are for your default optical configuration (e.g. f/1.4), and
the alternate table is for an optional second optical configuration (e.g. f/5.6).
TYPE IN: RESPONSE EXPLANATION
ACT 0 CR-LF Selects the standard OGC Table.
ACT 1 CR-LF Selects the alternate OGC Table.
ACT?
Queries the current setting.
ACT x Indicates the alternate table setting.
3.4.20 Strobe Polarity
The strobe output on the rear panel of the camera provides a trigger pulse for the user. The
polarity of the strobe signal is set by this command. The strobe output can drive a 50-ohm load
and has a pulse width of 5 microseconds. In double exposure mode only, the strobe output has a
pulse width of 800 nanoseconds.
TYPE IN: RESPONSE EXPLANATION
STP P
CR-LF Sets the polarity of the strobe output pulse to
positive.
STP N
CR-LF Sets the polarity of the strobe output pulse to
negative.
STP? Queries the strobe output pulse polarity.
3.4.21 Defect Conceal
Sensors are not perfect and have some pixels that react differently to light. These imperfect
pixels are sometimes different in intensity from their neighbors. It is possible to characterize a
sensor identifying the abnormal pixels and then to program their locations into the camera at the
factory. When defect concealment is turned on, the camera replaces the variant pixels with
information derived from nearby pixels, making the nonuniformity disappear.
TYPE IN: RESPONSE EXPLANATION
DEF ON CR-LF Enables defect concealment.
DEF OF
CR-LF Disables defect concealment.
DEF?
Queries the state of defect concealment.
3.4.22 Save
At start up, the camera always recalls Save 0. By entering SAV 3, for example, the current
settings will be saved to setup 3, and can be recalled by entering RST 3.
TYPE IN: RESPONSE EXPLANATION
SAV CR-LF Saves the current camera settings to the camera’s
internal memory. The user can now save up to 10
different operating states. The argument range is
from 0 to 9. These settings will be recalled by use
of the RST x command, where x is the operating
state previously saved.
NOTE: The Flash memory used by the SAVE command has a finite life of roughly 10,000 erase
and program cycles. Use this function as needed, but be aware of the flash memory life
cycle.
