Functions

Using the APPLy

Command

The APPLy command provides a high level method of programming

the generator. Selection can be made for function, frequency,

amplitude, offset and other parameters, which are associated with the

applied function. For example, the following statement outputs a 2 Vp-

p square wave at 1 MHz with a 0 V offset and 10% duty cycle using

APPLy:

APPL:SQU 1E6, 2, 0, 10

It is not necessary to enter every parameter with the APPLy

command. If only the frequency and offset need to be changed, omit

the other parameters while keeping the commas. The other

parameters will be set to the power-up default values:

APPL:SQU 10E6,,1

Alternatively, if just the first parameters need to be changed, omit the

commas. The other parameters will be set to the power-up default

values:

APPL:SQU 4e6,2

Queries can also be made on all parameters associated with a

standard function using the APPL: <function_shape>? query. For

example, if the generator was programmed using the above

APPLy:SQU command, query the square wave parameters using the

following query:

APPL:SQU?

The generator returns a string that contains all the parameters

associated with the square function similar to the following string:

"1.000000e+6,2.000,0.000,50"

The command:

APPLy:SINusoid

{<frequency>,<amplitude>,<offset>,<phase>}

programs the generator to output a sine waveform with frequency,

amplitude, offset, start phase and power parameters. Parameters are

not optional if the above APPLy command is used. Include all other

parameters in the command. The default settings for these

parameters are: 1 MHz, 2 Vp-p, 0 V, 0 and 1.
