RS-232/UART protocol decode and searching

RS-232 protocol decode with precise time-correlation between waveforms and listing

Keysight’s protocol viewer includes correlation between the waveforms and the selected

packet. The selected packet, highlighted blue row in the listing, is time-correlated with

the blue line in the waveform display. Move the blue tracking marker in time through

waveforms and the blue bar will automatically track in the packets window. Or, scroll

through the packet viewer and highlight a specific packet. The time-correlation tracking

marker will move to the associated point in the waveform.

RS-232 decode embedded in waveform

area

Utilize the oscilloscope waveform area to

display decode information. Minor ticks

indicate clock transitions and major ticks

show the beginning and end of each word

in the serial packet.

Full screen RS-232 listing

Fill the entire display with compact

protocol information using the full screen

listing. The protocol viewer window

shows the index number, time stamp

value, and data content for each serial

packet in the list. Scroll though all

decoded serial packets to find events of

interest or errors in the transmission.

Data in the listing window can be saved

to a .csv or .txt file for off-line analysis or

documentation.

Post-acquisition searching

Search acquired protocol listings using a

menu that is identical to the trigger menu.

Quickly find occurrences

Quickly move to next occurrence of a

specified event.
