F4: PULSE - Selects the Pulse waveform and then displays the pulse menu. Refer to section 3.6.5 for details.
F5: ARB - Selects the arbitrary waveform and then displays the Arbitrary menu:
Arbitrary Menu
F1: START
- Selects the starting address of the arbitrary waveform.
Note: The starting address always has to be an odd number. If an even number is
entered, it will automatically decrement one value to an odd number. For example, if
you set start address to 2000 and press ENTER, it will display 1999.
F2: LENGTH
- Selects the length of the arbitrary waveform. Use the START and LENGTH menu selection
to mark a selection of the waveform memory that will be executed.
Note: The length value must always be an even number. If you input an odd number
length, a message will pop up and say “Even wave length” and then decrement one
value to an even number. For example, if you entered 1001 as the length, the message
will pop up for one second and change the value automatically to 1000.
F2: SAVE ARB - Selecting this will save the current Arbitrary waveform data points so that it can be recalled
when revisiting the ARB menu later on or when power cycling the instrument.
Note: The 4076 and 4079 can both save multiple numbers of waveforms because the
instruments have one large memory bank to store up to 4,000,000 points total.
Essentially, the user can store multiple waves with various lengths in different
locations in the memory. This can be done simply by generating each of the waveforms
with different starting addresses. As long as the lengths of each do not overlap, user
can save as much waveforms with different lengths as desired (Total points of all
waveforms cannot exceed 4,000,000 points). If user has multiple waveforms to create
and do not want to remember all the different starting addresses and lengths, there is a
“STORE” and “RECALL” feature explained in section 3.6.6 that will allow you to
store and recall up to 50 settings (Note: Only 49 settings can be restores because 50 is
reserved for restoring last known working state of the instrument). Each setting can
save all the waveform parameters, configurations, modes, starting address, length and
more. (Refer to Table 3-2 in section 3.10 to see entire list of stored parameters) This
way, user can quickly recall back the different waves stored in the memory. Refer to
section 3.6.6 for details.
F3: MARK
- (Marker Output) Selects the marker output address of the signal to be available at the Marker
Out connector. The F2:ADDR, F3:LENGTH or F4:ON/OFF can be selected and the Marker
output signal can be available at any desired location address between the start and stop addresses
of the executed waveform. This marker output feature will allow you to generate a positive TTL
