F4: EDIT
- Refer to section 3.6.4 below for details.
**Changing one of the arbitrary parameters as start and length causes an update of the output waveform to the new
parameters. When exiting the Arbitrary Menu by selecting a different waveform, a message to save the Arbitrary
wave will be displayed. Select YES or NO to save the new waveform. This save functions the same as the SAVE
ARB function.
F3: AMPL/OFST
- Selects the Amplitude or Offset parameter.
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.
- Selects the Offset parameter. Change the offset by using the cursor keys, rotary knob or
numerical keypad. If a certain setting cannot be produced, the waveform generator will
display a “Setting Conflict” message.
F4: INTCLK/EXTCLK - Selects between using the internal clock or external clock.
For Model 4078 only:
For the 4078 with dual channels, channel 1 (CH1) is the MASTER channel. If selected
for external clock (EXTCLK), the same clock will also be applied to channel 2 (CH2) if
EXTCLK is also selected in CH2. (Note: There is only one BNC connector for external clock
input, which is common to both channels)
