For arbitrary waveforms used as the carrier waveform, the maximum
frequency depends on the number of points specified in the waveform.
The five built-in arbitrary waveforms can be output at a maximum
of 5 MHz (be sure to note the restrictions below).
For sine, square, and arbitrary waveforms (does not apply to ramp
and triangle waveforms), the relationship between the carrier
frequency and the minimum burst count is shown below.
If you attempt to set the carrier frequency to a value that is not valid,
the function generator will automatically adjust the frequency to the
maximum value allowed with the present burst count.
From the front panel, “
MAX VALUE” is displayed and the carrier
frequency is adjusted. From the remote interface, a -221, “Settings
conflict” error is generated and the carrier frequency is adjusted.
