Live Logic provides two channels of 500MS/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. Time based acquisition provides 2ns 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 2ns. 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.
Captured signals are displayed in timing diagram format. Pan and zoom controls are provided on the instrument front panel, as 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.
After you have captured a waveform, display annotations can be added to highlight specific characteristics. These annotations can be generated automatically using a protocol decoder such as I2C, SPI, RS232, or LIN. Annotations can also be placed manually using time marks which display time, notation marks which display a user entered note, or comments which display at the bottom of the waveform.
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.
