Show bus
If enabled, the resulting bus signal and bus values are displayed in the diagram. Select
the presentation type for the bus signal with "Bus display" on page 930.
Remote command:
BUS<m>:PARallel:DISPlay:SHBU on page 2205
Bus display
Defines how the parallel bus is displayed.
"Comb"
Displays the decoded bus signal with bus values. When at least one
digital channel changes its value, the bus value changes too.
"Analog"
Displays the bus values as signal amplitudes, similar to an analog
waveform. Thus, a quasi-analog waveform is created.
Remote command:
BUS<m>:PARallel:DISPlay:BTYP on page 2205
Data format
Sets the data format of bus values, which are displayed in the decode table and on the
comb bus display. Available formats are: Hex, ASCII, octal, binary, signed, and
unsigned.
Signed and Unsigned are integer data types with maximum 16-bit length. Unsigned is
used for positive integers. Signed is used for positive and negative integers.
If the target file format is BIN, you can save only signed and unsigned binary data. The
data format "Signed" writes signed data; all other formats are saved as unsigned
binary data.
Remote command:
BUS<m>:PARallel:DATA:FORMat on page 2204
Clocked bus
If a bus is a clocked bus, one of the digital channels serves as clock of the bus.
For an unclocked bus, the logical state of the bus is determined for each sample. For a
clocked bus, the logical state is determined only at the specified clock edges.
The settings are only available for "Bus1" and "Bus2".
Enable ← Clocked bus
Enable this option for a clocked bus.
Remote command:
BUS<m>:PARallel:CLON on page 2205
Show table ← Clocked bus
The decode table is only available for clocked buses to check the data words.
If enabled, a results box opens with decoded values of the bus signal and its time.
Each clock edge corresponds to one row in the table.
