		Triangle	100 ∝Hz	100 kHz	Hz

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.

Number of Arb Points	Minimum Frequency	Maximum Frequency
8 to 8,192 (8K)	100 ∝Hz	5 MHz
8,193 to 12,787 (12K)	100 ∝Hz	2.5 MHz
12,288 to 16,000	100 ∝Hz	200 KHz

•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? [MINMAX] queries the frequency setting for the function currently active. Returns a value in hertz.

FREQuency:STARt

[SOURce:]FREQuency:STARt <frequency>MINMAX 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.
