8-3 Setting Bit Depth
The TS3 can record and save 10-bit or 8-bit data. The advantage of recording 10-bit data is that it
gives more fl e xibility in post-processing the imagery. The disadvantage is that it takes more
memory to record or save 10-bit data. When recording, you will get about 25% fewer files, and 25%
less recording time.
When saving 10-bit data (to a mass storage device) in TIFF (RAW) format, the actual file type is a 16-
bit file, so it is su b stantially la ger than an 8-bit mono file. The 10-bit (R W) color image, however is
not colorized--it is a RAW Bayer image (not “colorized,” which would make it about 3x as large), so it is
about 2/3 the size of the 24-bit color file (8 bits per each of 3 olor channels).
To choose the recording bit depth:
1. Navigate to the Record Menu.
2. Select Bit Depth.
3. Select 8-low, 8-mid, 8-high, or 10-bit. If any of the 8-bit mappings are chosen, the live image will
immediately reflect th t change. If 10-bit is chosen, the displayed live image will default to 8-high.
If Bit Depth is set to 10 in the Record Menu, a bit depth selection will appear in the The Displ a y
Menu. The choices here are 8-low, 8-mid, and 8-high. This selects the 8-bits used for the display and
for saving to media.
8-4 Configuring the Trigger
The TS3 uses a fi x ed, selectable circular bu ff er to record into. The
session length is determined by the user (see “7-8 Storage Setup”
on page 59). This section
e xplains how to set the trigger position
within the bu ff er. For an explanation on h o w the circular bu ff er
works and how to decide on the proper trigger position see
“Application No t e 3: Trigger Position and the Ci r cular Bu ff er” on
page 97.
To Set the
Trigger Position
in the TS3:
1. Open the Record Settings T ab.
2. Select either the “Use Percent” or “Use Frames” radio bu tt on.
The slider and edit box represent the session bu ff er, which is
the camera memory you will be recording into. The trigger position, e xpressed either in %
or frames.
3. Set the position b y moving the slider or typing into the edit box or using the spinner bu tt ons.
Enabling the External Trigger
There are times when y ou wish to acti v ate the trigger electrically, either to sync the trigger with
other cameras or signals, or to maintain greater precision than can be expected through the
soft
w are trigger in Fas
M
otion
1. Open the Record Settings T ab.
2. Click on the pull-down in the External Trigger box to expose the choices, which are: Rising, Falling,
or Disabled.
3. Choose “Rising” for rising signals or a switch opening and “Falling” for a falling signal or switch
closure.
Please refer to “Appendix D: Power and I/O Connections” on page 82 for connection information
and warnings.
