Advanced Analog Trigger
Advanced Analog Triggered Recorder
This addon uses calculated result to provide trigger mode for all
Windaq-based instruments, including WinDaq Starter kits, including
DI-194, DI-148, DI-158, DI-710 and DI-718.
It offers industry's first
Trigger Mode , e.g.
dV/dt>30. With this feature, one
can trigger on a glitch riding on a slow moving signal swinging from rail to
Also available is
Analog Calculated Trigger Mode, e.g. Channel 1 * Channel 2
>40. For example, the power consumption based on the
readings of voltage and current.
Blue: Filling up pre-trigger
Yellow: Waiting for
condition to be FALSE first
Green: Waiting for condition
to be TRUE
Red: Filling up post-trigger

To use the reading from a channel, use #n. For example, #0
is the reading from the first enabled channel in Windaq
To access the sample rate, use #@.
You can use earlier readings to form a more complicated
math expression. To do so, add a letter after #, and alphabet
order of the letter represents the delay, such as:
#0 is the reading from channel 0
#A0 is the reading from channel 0, one scan earlier
#B1 is the reading from channel 1, two scans earlier
Readings from up to 26 scans earlier can be used, for example, #Z0.
For example: use ( #0-#A0)*#@, or #0-#A0, to form a two-point
The mystery of channel index!
The math equation parser uses standard English (United
States) notation without the present of digital grouping symbol,
the decimal point must be "." (period) instead of ","
(comma). If your Regional and Language Setting is not English
(United States), you may need to adjust it
