•You can substitute "MINimum", "MAXimum" or "DEFault" in place of a specific value for any of the above three parameters. MIN selects the lowest value, MAX selects the highest value and DEF selects the default setting.

Output Frequency Minimum frequency is the same for all functions. Maximum frequency is dependent

on the function selected as shown in the following table.

Function	Minimum	Maximum Frequency
	Frequency
Sine	100 ∝Hz	15 MHz
Square	100 ∝Hz	15 MHz
Built-In Arbs a	100 ∝Hz	200 kHz, 2.5 MHz or 5 MHz b
Ramp	100 ∝Hz	100 kHz
Triangle	100 ∝Hz	100 kHz

a.There are five built-in arbitrary waveforms stored in non-volatile memory: sinc, negative ramp, exponential rise, exponential fall and cardiac. These waveforms are shown on page 48. The five built-in arbitrary waveforms can be output at a maximum of 5 MHz.

b.Maximum frequency for arbitrary waveforms you generate depends on the number of points

specified in the waveform. The maximum output frequency decreases as you specify more points

in the waveform (see below).

.

Number of Arb Points	Minimum Frequency	Maximum Frequency
8 to 8,192 (8k)	100 ∝Hz	5 MHz
8,193 to 12,287 (12k)	100 ∝Hz	2.5 MHz
12,288 to 16,000	100 ∝Hz	200 kHz

•Possible Output Frequency Conflict with a Function Change: The output frequency is automatically adjusted if you change the function from SINE or SQUARE (MAX frequency = 15 MHz) to RAMP, TRIANGLE or a Built-In Arb, if the current frequency is greater than that of the maximum frequency of the new function. For example, the maximum frequency of a sine wave is 15 MHz while the maximum frequency for a triangle wave is 100 kHz. If the current output is a sine wave at 1 MHz and you change the function to triangle wave which cannot output at 1 MHz, the function generator automatically adjusts the output to the upper frequency limit for a triangle wave (100 kHz). This function change will also generate a -221 "Settings conflict" error.

•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
