Arbitrary. Opens the Arbitrary Waveform window . This

button is available only if your scope has an arbitrary waveform

generator .

Start Frequency. Type in this box or use the spin buttons to

select the frequency. If the scope device has a frequency sweep

generator, then this box sets the start frequency of the sweep.

Amplitude. The amplitude of the waveform measured from

peak to peak. For example, if Amplitude is 1 V and Offset is 0

V, the output will have a negative peak of -0.5 V and a positive

peak of +0.5 V.

Offset. The mean value of the signal. For example, when Offset

is 0 V, a sine or square wave will have equal positive and

negative peak voltages.

Sweep mode controls

Active. Tick this box to enable sweep mode. If the box is not

ticked, the generator will operate at a fixed frequency set by

the Start Frequency control.

Sweep Type. Specifies the direction in which the frequency is

swept.

Stop Frequency. In sweep mode, the generator stops

increasing the frequency when it reaches the Stop Frequency.

Frequency Increment. In sweep mode, the generator

increases or decreases the frequency by this amount every

Increment Time Interval.

Increment Time Interval. In sweep mode, the generator

increases or decreases the frequency by Frequency Increment

each time this interval ends.
