Agilent Technologies E1441A Number of Arb Points, Minimum Frequency, Maximum Frequency

Keep in mind that the carrier frequency is different than the “burst rate” which specifies the interval between bursts (triggered mode only).

Burst Carrier frequency: 10 mHz to 5 MHz (100 kHz for triangle and ramp). The default is 1 kHz. You can use sine, square, ramp, triangle, or arbitrary waveforms for the carrier waveshape.

Be sure to note the restrictions for carrier frequency and burst count shown on the following pages.

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).

Table 2-6.

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

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.

Table 2-7.

Carrier Frequency	Minimum
	Burst Count
10 mHz to 1 MHz	1
>1 MHz to 2 MHz	2
>2 MHz to 3 MHz	3
>3 MHz to 4 MHz	4
>4 MHz to 5 MHz	5

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. A -221, “Settings conflict” error is generated and the carrier frequency is adjusted.
