APPLy Commands

The APPLy command provides the most straightforward method to program the function generator. It allows you to select the output function, output frequency, output amplitude and a dc offset voltage on which the output signal resides in a single command.

Note The APPLy commands not only set the instrument’s function, frequency, amplitude, and offset, it also sets Duty Cycle to 50%, turns Modulation OFF, sets the TRIG:SOUR to IMM, and sets the TRIG:SLOPE to POS. Because of this, where a sequence of commands is needed to configure the instrument, and one of them will be a SOUR:APPLY command, the APPLy command must be first.

APPLy Command Parameters

Each APPLy command specifies the function to be output followed by three parameters.

Subsystem APPLy:<FUNCTION> [<frequency> DEFault[,<amplitude> DEFault[,<offset>]]]

Syntax

Syntax Example Executing the following statement will output a sine wave with frequency of 5 kHz and amplitude of 3 Vpp with a -2.5 volt offset:

"APPL:SIN 5.0E+3, 3.0, -2.5" default units are hertz, Vpp, VDC

Because of the use of optional parameters in the APPLy commands (enclosed in square brackets), you must specify frequency to use the amplitude parameter, and you must specify both frequency and amplitude to use the offset parameter. The following statement is valid (frequency and amplitude are specified; offset is omitted):

"APPL:SIN 5.0E+3, 3.0"

However, you CANNOT specify amplitude or amplitude and offset without specifying

afrequency.
