œ
For arbitrary waveforms that you create and download to memory,
the maximum frequency depends on the number of points specified in
the waveform. As shown below, the maximum output frequency
decreases as you specify more points in the waveform. The five
built-in arbitrary waveforms can be output at a maximum of 5 MHz.
œ
Possible Conflict with Function Change : The output frequency is
automatically adjusted if you select a function whose maximum
frequency is
less than that of the currently active function.
For example, if you output a 1 MHz sine wave and then change the
function to triangle wave, the function generator will adjust the
output to 100 kHz (the upper limit for triangle waves).
From the
remote interface, a -221, “Settings conflict” error is generated and the
frequency is adjusted.
œ
Possible Conflict with Duty Cycle (square wave only) : For output
frequencies above 5 MHz, the duty cycle is limited to values between
40% and 60% (below 5 MHz, the range is 20% to 80%). The duty cycle
is automatically adjusted if you select a frequency that is not valid
with the present duty cycle. For example, if you set the duty cycle to
70% and then change the frequency to 8 MHz, the function generator
will automatically adjust the duty cycle to 60% (the upper limit for
this frequency).
From the remote interface, a -221, “Settings conflict”
error is generated and the duty cycle is adjusted.
