terminal
An object or region on a node through which data passes.
terminal count
The highest value of a counter.
t
gh
Gate hold time.
t
gsu
Gate setup time.
t
gw
Gate pulse width.
Timebase
The reference signals for controlling the basic accuracy of time or
frequency-based measurements. For instruments, timebase refers to the
accuracy of the internal clock.
t
out
Output delay time.
Traditional NI-DAQ
(Legacy)
An upgrade to the earlier version of NI-DAQ. Traditional NI-DAQ
(Legacy) has the same VIs and functions and works the same way as
NI-DAQ 6.9.

trigger
1. Any event that causes or starts some form of data capture.
2. An external stimulus that initiates one or more instrument functions.
Trigger stimuli include a front panel button, an external input voltage
pulse, or a bus trigger command. The trigger may also be derived from
attributes of the actual signal to be acquired, such as the level and slope
of the signal.
t
sc
Source clock period.
t
sp
Source pulse width.
TTL
Transistor-Transistor Logic—A digital circuit composed of bipolar
transistors wired in a certain manner. A typical medium-speed digital
technology. Nominal TTL logic levels are 0 and 5 V.
