•
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.
