MicroBench MB-500 Live Logic user application window with timing display

Live Logic

Live Logic provides two channels of 400MS/s digital capture for active logic signals with a live oscilloscope-like display. It utilizes standard 10MΩ, 10x scope probes for easy browsing of your logic signals. A Live Logic acquisition provides 2.5ns resoltion regardless of the time span acquired. For example, you can capture several I2C transactions that happen only once each second and still resolve edge times to 2.5ns. Triggering can be set to any logic combination of the input signals or can come from another selected tool.

Live Logic includes a built-in voltmeter always showing the average DC voltage at the scope probe tip. This is useful to check power supply levels or high speed PWM outputs. LED indicators on each channel indicate signal activity at the probe tip.

Activity Indicator
Live Logic includes front panel LED activity indicators on each channel that flash any time there is signal activity at the probe tip.

Waveform Display
Captured signals are displayed in timing diagram format. Pan and zoom controls are provided on the instrument front panel, in keyboard accelerators, in drop down menus, or can be controlled by the mouse wheel making navigation quick and simple. Goto next/prior edge and Goto Trigger are also great navigation aids.

Waveform Measurements
Each channel can be assigned one of four measurements: Frequency, Period, Pulse width, or Duty cycle. These measurements are displayed next to the captured waveform.

Waveform Annotations
After you have captured a waveform, display annotations can be added to highlight specific signal characteristics. Annotations include time marks, notation marks, or comments which display at the bottom of the waveform.

Protocol Decode
Protocol decode annotations can be generated automatically using one of the protocol decoders. Live Logic includes decoders for I2C, SPI, RS232, and LIN bus. Decode annotations can be customized for your application by writing your own decode definition scripts.

Saved Waveforms
Captured waveforms can be saved by selecting File, Save As... in the Live Logic tool window. All data and display annotations are saved to a CSV file. The Live Logic CSV file can be opened at any time using the MB-500 application - the MB-500 instrument does not need to be connected to view waveforms. The waveform CSV can also be opened in a spreadsheet or custom program to do further timing analysis.
