Basic controls

Signal generator dialog for the

PicoScope5204

Signal On. Tick this box to enable the signal generator.

Signal Type. Select the type of signal to be generated. The list of signal types

depends on the capabilities of the scope device.

Import. Opens a file selection dialog that allows you to import an arbitrary waveform

file. The file will be loaded into the arbitrary waveform generator and the generator

switched on. This button is available only if your scope has an arbitrary waveform

generator.

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.

7.7.1.2

Sweep controls

The signal generator normally generates a fixed frequency set by the Start

Frequency Control. In sweep mode, it generates a frequency that varies between

two specified limits.

Active. Tick this box to enable sweep mode.

Sweep Type. Specifies the direction in which the frequency is swept.
