Configuring Sine Wave

This section is to introduce how to configure the sine wave function.

Explanation

A sine wave has an amplitude, an offset, and a phase relative to a synchronous pulse. It can use
high voltage value and low voltage value to set its amplitude and deviation.

Example

The following wave can set by SCPI command, high voltage value and low voltage value can
replace :CHANnel1:BASE:AMPLitude and :CHANnel1:BASE:OFFSet

The following command can generate the sine wave as shown above.

:CHANnel1:MODe CONTinue
:CHANnel1:BASE:WAVe SINe
:CHANnel1:BASE:FREQuency 2000
:CHANnel1:BASE:HIGH 2
:CHANnel1:BASE:LOW 0
:CHANnel1:BASE:PHAse 20
:CHANnel1:OUTPut ON

Configuring Square Wave

This section is to introduce how to configure the square wave.

Explanation

A square wave has an amplitude, an offset, and a phase relative to a synchronous pulse. It also has
duty cycle and period. It can use high voltage value and low voltage value to set its amplitude and
deviation.
