Software Options


The UART and RS-232 Trigger Decode (TD) and Trigger, Decode, Measure/Graph and Physical Layer (TDME) solutions both provide high performance triggers and transparent color-coded decode overlays, protocol tables, and search capabilities. The TDME option also provides Measure/Graph (M) capability with automated measurement and graphing tools and Eye Diagram (E) capability for physical layer signal assessment and debug.

9-bit "Address" or "Wakeup" Triggering ("T")

Most UART triggers assume a maximum of 8 data bits (excluding stop/start and parity bits) in a single byte. However, our solution supports 9-bit data bytes for situations in which a UART protocol is utilized for Address, Wakeup or other communication to another peripheral, preceding the normal serial data byte transmission.

Interframe Message Time Setup for Proprietary UART-based Protocols ("T" and "D")

UART byte-based serial data signals with proprietary formats are often used. Given the flexibility of the setup of our trigger and decoder, it is often possible to use the Interframe Message Time Setup to "packetize" consecutive bytes into one Message Frame, and then trigger on in serial data in a particular byte location in the complete multi-byte Frame. Then, the UART decoder may be used to decode information as a complete Frame instead of individual Bytes.

Conditional DATA Trigger Setup ("T")

The trigger permits a conditional (<. <=, =, >, >=, <>, inside a range, outside a range) setup for the DATA condition. This is especially useful in situations where abnormal events should be monitored.

Intuitive, Color-coded Decode Overlays ("D")

A transparent overlay with color-coding for specific portions of each protocol and the entire message frame makes it easy to understand your serial data information. Unlike other solutions, with protocol decode information away from the signal, our solution correlates the waveform and the protocol decode directly on the display. As the acquisition length is expanded or shortened, the decode overlay will adjust to show you just the right amount of information.

Interactive Table Summarizes Results ("D")

Turn the oscilloscope into a protocol analyzer with a tabular display of decoded information. Customize the table to show only the data of interest and touch a message in the table to automatically zoom to it and display it on the screen. Export the table for offline analysis. Up to four different decoded signals of any type may be simultaneously displayed in the table.

Measure/Graph Tools for Validation Efficiency ("M")

Quickly validate cause and effect with automated timing measurements to or from an analog signal or another serial message. Make multiple measurements in a single long acquisition to quickly acquire statistics during corner-case testing. Serial (digital) data can be extracted to an analog value and graphed to monitor system performance over time, as if it was probed directly. Complete validation faster and gain better insight.

Eye Diagrams ("E")

Rapidly display an eye diagram of your packetized low-speed serial data signal without additional setup time. Use eye parameters to quantify system performance and apply a standard or custom mask to identify anomalies. Mask failures can be indicated and can force the scope into Stop mode.
