3.6.1 PARAMETER Key
This key selects and displays the waveform frequency, amplitude, offset and external reference and allows changing the parameter
data. When the Arbitrary Waveform is selected, the display shows also the waveform rate.
Frequency Menu
F1: FREQ - (Frequency) Selects and displays the frequency. Change the frequency setting using the cursor keys and
rotary knob or numerical keypad. If a certain wavelength can't produce the waveform at the desired
frequency, the waveform generator displays an “Out of Range” error message.
F3: AMPL/OFST - Selects the Amplitude or the Offset parameters.
In Arbitrary mode this setting defines the maximum peak-to-peak amplitude of a full-scale waveform. If
the waveform does not use the full scale of data (-8191 to +8191), then its actual amplitude will be smaller.
Amplitude Menu
Setting the Amplitude
The following equation represents the relative output amplitude voltage relationship between the front-
panel amplitude peak-to-peak setting and the data point values in waveform memory:
