5. Use the general purpose knob, the front panel arrow buttons or k eyboard arr ow
keys to select an event logic value line in the table.
6. Push the Tabl e J um p side button to ON to enable entering a ju mp line number.
To clear a value, push the Tab le Ju mp side button to Off.
7. Push the Jump To side button and then use the general purpose knob,
front–panel keypad, or keyboard numeric keys to enter a line number.
8. Repeat steps 5 through 7 to enter jump line numbers for other event table
values.
9. Push the CLEAR MENU button on the front–panel to return to the sequence
table display.
Timing. The Timing function controls when a jump occurs in t he wa veform output
sequence. Selecting ASync causes the instrument to jump to the sp ecified sequ ence
table line as soon as an event goes true.
Selecting Sync causes the instru ment to jump to the specified sequence ta ble line
after completing the output of the current waveform memory. For example,
suppose that an event occurs during the sec ond rep eat co unt of a line on which th e
waveform is defined to be output three t imes. The jump occurs after com pleting the
second output repetition and before starting the third output repetition.
To set the timing value in the Event Jump screen, push the Timing side menu
button to toggle between Sync and ASync.
Strobe. You can set the instrument to enable or disable strobing in the EVENT IN
signals. Event signals must be input to the EVENT IN connector on the r ear pane l
when you run the sequence in Enhanced mode. You can input four event signals
and one strobe signal in the connector.
When Strobe is set to Off, the instrument rea ds the event signals at the timing of
every two internal clock cycles, and updates the e vent value if a state transition in
the event signals are found.
When Strobe is set to On, the instrument re ads the event signals when the strobe
signal goes to low state (Enable), and updates the e ven t val ue if a state tra nsition in
the event signals are found.
If you set the strobe signal to low state after all the event signals have finished the
state transitions and have been in stable period, the instrument can read the event
signal state without error. This prevents an incorr ect action in the
AWG710&AWG710B Arbitrary Waveform Generator sequence control. Figure
3-32 illustrates an signal timing example.
