(2) Exposure time setting: Electronic Shutter [NMD S
・
SHT n]
Exposure and readout repeat along with the operation of the electronic shutter
according to the sequence set internally. The exposure time is set with the SHT n
command. This setting is made in units of one horizontal scan cycle for each scan
mode. Exposure timing and exposure time is as following.
