Features and Functions

Remote Interface Operation

FUNCtion {SINusoidSQUareRAMPUSER}

You can also use the APPLy command to select the function, frequency, amplitude, and offset.

Carrier Frequency

The maximum carrier frequency depends on the function selected as shown below. The default carrier frequency is 1 kHz for all functions.

Table 2-5Carrier frequency for PM

Function	Minimum frequency	Maximum frequency

Sine	1 μHz	20 MHz

Square	1 μHz	20 MHz

Ramp, Triangle	1 μHz	200 kHz

Arbitrary	1 μHz	200 kHz

Soft Front Panel Operation

On the Frequency panel as shown in Figure 2- 3, input the desired frequency value and select the unit from the drop down list.

Remote Interface Operation

FREQuency {<frequency>}

You can also use the APPLy command to select the function, frequency, amplitude, and offset.
