Mixed-Signal Operation
can also use partially identical logic channels in the two
possible buses. If you select PARALLEL CLOCKED as
BUS TYPE, you can also use the bottom soft menu key
CONTROL WIRES to select sources for CHIP SELECT, and
you can use the universal knob to select the settings for
CLOCK. The soft menu key ACTIVE is used to determine if
the chip select signal High or Low Active is selected.
The soft menu key SLOPE allows you to toggle between ri-
sing, falling and both slopes. The active selection is always
highlighted in blue and is listed after the label CLK in the
bit source window. Press the MENU OFF button to return
to the BUS main menu.

The decoded values will be shown in the cells/tables of
the buses according to the selected format. The next soft

You can use the POSITION control knob to determine the
position of the bus display on the screen. The VOLT/DIV
knob allows you to determine the size of the table display.
This may be particularly useful for the binary display as it
allows the display of the complete value in up to 4 rows
even for short tables.

12 .4 Cursor Measurements for Logic Channels
If the logic channels are activated, you may select several
parameters via cursor measurements (CURSOR MEASURE
button).
For all activated logic channels of a POD, you can choose
from the following measurement types:

button).
For all activated logic channels of a POD, you can choose
from the following measurement types:
❙TIME:
The display will include the time position of both cursors
relative to the trigger time, the time difference between
the two positions and the resulting frequency.
relative to the trigger time, the time difference between
the two positions and the resulting frequency.
❙RATIO X:
In this measurement type, three cursors are used to
display a time ratio between the first two cursors plus the
first and third cursor. The results are shown in floating
point format, in percent, in degrees and in radians.
