The soft menu
DISPLAY SETUP
opens a menu to select the
display format and its extent. The universal knob in the submenu
allows you to choose the format to decode the bus values. You
can choose from the following formats:
– BINARY
– HEXADECIMAL
– DECIMAL
– ASCII
The decoded values will be shown in the cells/tables of the buses
according to the selected format. The next soft menu key
BITS
can also be used to activate or deactivate the table display for
the individual bus bits.
A white dot in the short menu indicates that a BUS is activated.
You can now 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 dis
-
play of the complete value in up to 4 rows even for short tables.
12.3 Cursor measurements for the logic channels
If the logic channels were activated, some parameters may be
measured with the cursors. For all activated logic channels
of a POD these measurements are available: TIME, RATIO X,
V MARKER. The results will be as follows:
TIME:
The time position of both cursors relative to the trigger time
position will be indicated; also the time difference between the
two cursor positions from which the frequency is calculated.
RATIO X:
In this mode 3 cursors are used. The time ratios between the
first and the second and between the first and the third will
be shown. The presentation will be in floating point format, in
percent, in degrees, and in radians.
V MARKER:
With the logic channels the logic value of the selected POD will
be measured at the position of the respective cursor and shown
in hexadecimal and decimal formats.
12.4. Auto measurements for logic channel
If the logic channels are switched on, you can use the au-
tomeasure function to measure some parameters. These
parameters can be chosen from FREQUENCY, PERIOD, PULS-
WIDTH +/–, DUT/–, DELAY, PHASE, BURSTWIDTH,
NUMBER PULSE +/– and NUMBER EDGE pos. / neg. . Like all
auto-measurements you can switch on statistic on page two
of the automeasure menu.
