Parameters
Comments • 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.
• 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).
A -221, “Settings conflict” error is generated and the frequency is adjusted.
FREQuency?
[SOURce:]FREQuency? [MIN|MAX] queries the frequency setting for the function
currently active. Returns a value in hertz.
FREQuency:STARt
[SOURce:]FREQuency:STARt <frequency>|MIN|MAX sets the start frequency.
Select from 10 mHz to 15 MHz (100 kHz for triangle and ramp). The sweep is phase
continuous over the full frequency range. The default is 100 Hz.
MIN = 10 mHz. MAX
= 15 MHz. The start frequency setting is stored in volatile memory.
