13.3 Triggering on logic channels
Each logic channel can be used as trigger source. Using the pattern trigger, you can
trigger on logical combinations of analog and digital channels. Also, you can define a
trigger holdoff time.
If you trigger on logic channels, the threshold is used as trigger level.
The following trigger types are available if the trigger source is a logic channel:
●
Edge
●
Width
●
Pattern: the pattern can use all active logic channels
●
Timeout
For analysis of serial protocols, you configure the protocol using logic channels as
sources, and trigger on trigger type "Serial
Bus". For details, see the chapter describ-
ing the relevant bus.
13.4 Analyzing logic channels
The main analysis tools for logic channels are serial protocol analysis ([Protocol]) and
the pattern triggers.
Furthermore, you can display all logic channels and change the vertical scale position.
You can also zoom into the display ([Zoom]).
To measure logic channels, you can use automatic and cursor measurements as
usual.
See also Chapter 7.2, "Automatic measurements" , on page 131 and Chapter 7.3, "Cur-
sor measurements" , on page 141.
You can also export the waveform data: [Save Load] key > "Waveforms"
13.5 Parallel buses
The R&S RTB2000 can display and decode up to 16 lines of a parallel bus. You can
assign the logic channels to the bus bits individually.
To trigger on parallel buses, use the pattern trigger, see Chapter 5.7, "Pattern trigger" ,
on page 82.
