F1: Frequency – Selects and displays the frequency.
Change the frequency setting using the cursor keys,
rotary knob, or numerical keys.
F2: Amplitude – Selects and displays the amplitude.
Change the amplitude setting using the cursor keys,
rotary knob, or numerical keys.
F3: Offset – Selects and displays the offset
parameter. Change the offset by using the cursor
keys, rotary knob, or numerical keys. If a certain
setting cannot be produced, the waveform generator
will display a “ Setting Conflict” message.
Amplitude and offset settings interact and are bound
by hardware restrictions. To obtain the desired
waveform, the amplitude and offset must satisfy the
following formula:
(Vp-p)/2 + |offset| <= 5 volts
F4: Symmetry – When the Square or Triangle
waveforms are selected, the SYMMETRY (duty
cycle) parameter is available. Change the symmetry
(Triangle) or duty cycle (Square) by using the cursor
keys, rotary knob, or numerical keys. If a certain
setting cannot be produced, the waveform generator
will display a warning message.
