3.6.3 ARBITRARY Key
When selected displays the following screen:
Arbitrary Menu
F1: FREQ/RATE - (Frequency) Selects and displays the frequency. Change the frequency setting using the
cursor keys, rotary knob or numerical keys. If a certain wavelength can't produce the
waveform at the desired frequency, the waveform generator displays an “Out of Range” error
message. Displays the Point Rate (for Arbitrary Waveform only). The Rate parameter governs
the rate at which waveform points are executed, and thus the frequency of the waveform
output. When you set this parameter, the waveform generator will keep that execution rate for
all waveform lengths until it is changed.
F2: ARB
- Selects the Arbitrary editing menu:
Arbitrary Editing Menu
F1: START/LENGTH - 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.
- 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
