F1: SINE -
Selects the sine waveform.
F2: SQR
- Selects the square waveform and displays the waveform duty cycle that can be changed from 20% to 80% up
to 10MHz and 40% to 60% to 30MHz.
F3: TRI
- Selects the triangle waveform and displays the waveform duty cycle that can be changed from
10% to 90%.
The triangle maximum frequency is 5MHz.
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 400,000
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
400,000 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
