4.2

Output Frequency Sweep Wave

In frequency sweep mode, the output frequency of the instrument is in a linear or logarithmic change from

the start frequency to the stop frequency during the specified sweep time. Sine wave, square wave, ramp

wave and arbitrary wave (except DC) can all generate the frequency sweep output.

4.2.1

Select Frequency Sweep

1)

Enabling Frequency Sweep Mode

Press Mode

Sweep

Linear

to turn on frequency sweep mode, the instrument will output the frequency

sweep wave according to the currently setting. The linear frequency sweep setting as shown in the

following figure.

2)

Select Frequency Sweep Wave

The frequency sweep wave can be sine wave, pulse wave, ramp wave or arbitrary wave. The default is sine

wave. After frequency sweep mode is selected, press Wave key to enter the carrier wave interface.
