UltimaSerial WinDaq Add-on: Advanced Analog Triggered Recorder 
 

Advanced Analog Triggered Recorder 

This addon uses calculated result to provide trigger mode for all Windaq-based instruments

It offers industry's first Analog Derivative 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 rail. 

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.

Please consider Advanced Trigger Excel Link instead if Excel Link is needed

 

  • Advantage and Applications 

    • Huge pre- and post- trigger buffer. 

    • Industry's first Analog Derivative Trigger Mode©, e.g. dV/dt>30. For example, one can trigger on a glitch riding on a slow moving signal swinging from rail to rail

    • Trigger on combination of conditions, e.g. Channel 1>0.2 and Channel 2 <3. This is especially important in test that has multiple variables 

    • Analog Calculated Trigger Mode, e.g. Channel 1 * Channel 2 >40. For example,  the power consumption based on the readings of voltage and current, 

    • Provide trigger mode for all Windaq-based instruments, including WinDaq Starter kits. 

  • Recording capability

    • Auto increment for .WDQ file name 

    • Up to 8000 event-marked trigger captures per file.

    • File size: up to 4GB

  • Performance and Features

    • Maximum throughput rate depends on many factors.

    • If there is no trigger for more than 3 + (pre-trigger period) + (post-trigger period) seconds, the display turns into free-run mode, just like a real scope's trigger mode

    • Here are some suggestions on how to maximize the performance:

      • Enable as few WinDaq channels as possible. 

      • If the sample rate is a constant, use a constant in the equation instead of referring to #@

    • All important settings are retained between sessions

    • Trigger States and their indicators

      1. Blue: Filling up pre-trigger buffer

      2. Yellow: Waiting for condition to be FALSE first

      3. Green: Waiting for condition to be TRUE

      4. Red: Filling up post-trigger buffer

  • Chart Features

    • Plot all (up to 16) WinDaq channels

    • Sizeable Chart

    • Trigger Indicator

    • Use mouse wheel or buttons to zoom in/out

    • Please note, each time the form is resized, the chart will be cleared

  • True math expression with many predefined operators and functions

    • Operators include: +, -, *, /, ^, %, &, |, !, >, >=, <, <=, !=, ==

    • Functions include: abs, floor, hex, round, log, sqrt, ceil, log10, acos, asin, atan, sin, sinh, cos, tan, cosh, tanh

    • 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 derivative

        •

      • Must read: 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
