low (0.4 V or less), the sequence stops and waits for another high TTL signal to continue. This mode will
cut pulses, with a new pulse restarting once the high signal returns.
4. The
Sequence Options
(Fig.
) define the parameters of each pulse sequence for output channels. These param-
eters are defined with each channel type. Should a parameter chosen be impossible to apply to a sequence (For
example, a
Time ON
greater than 1/
Frequency
), the color of the option boxes will turn
RED
.
5. The
Sequence Preview
(Fig.
) section allows visualization of the output sequence that will play by selecting the
channel in the graph.
6. The
Apply
button (Fig.
) will generate the defined channel OR update an already configured channel with any
changes.
Digital I/O Channels
With the
Digital I/O
channels, each digital channel can be configured as an output or an input and create TTL (On/Off)
pulse sequences. Each numbered channel corresponds to the same number digital channel on the console. Pulse se-
quences have different parameters depending on the
Channel Mode
, which can be
Continuous
or
Square
for output
sequences and
Input
for input signals. The
Channels Configuration
window contains the following elements for a Digi-
tal I/O channel.
Figure 3.8:
Channel(s) configuration window, Digital I/O CW
• The
CW(Continuous Wave)
channel mode (Fig.
) allows the creation of a continuous TTL pulse sequence. The
following elements appear in the
Sequence Options
box.
1. The
Starting Delay
defines the time between the activation of the pulse sequence and the beginning of the
signal.
2. The
Time ON
defines the length of time the continuous signal is active. Should the time chosen be 0, the
signal will continue until the pulse sequence is stopped manually.
3. The
Total Duration
shows the total expected duration of the pulse sequence. Should the duration be infinite,
the box will display
∞
. If there is an error in parameter selection, this box will display
N/A
.
