Agilent Technologies E1441A user service APPLy:SQUare, APPLy:TRIangle, APPLy:USER, APPLy?

APPLy:SQUare

[SOURce:]APPLy:SQUare [<frequency>[,<amplitude>[,<offset>]]] is used to output a square wave with the specified frequency, amplitude and dc offset. For example, a square wave with the same parameters as the syntax example is shown below:

"APPL:SQU 5.0E+3, 3.0, -2.5"

Comments • Square Wave Frequency and Possible Conflict with Duty Cycle:

For output frequencies above 5 MHz, the duty cycle is limited to values between 40% and 60% (below 5 MHz, the range is 20% to 80%). The duty cycle is automatically adjusted if you select a frequency that is not valid with the present duty cycle. For example, if you set the duty cycle to 70% and then change the frequency to 8 MHz, the function generator will automatically adjust the duty cycle to 60% (the upper limit for this frequency). A -221 "Settings conflict" error is also generated.

APPLy:TRIangle

[SOURce:]APPLy:TRIangle [<frequency>[,<amplitude>[,<offset>]]] is used to output a triangle wave with the specified frequency, amplitude and dc offset. For example, a triangle wave with the same parameters as the syntax example is shown below:

"APPL:TRI 5.0E+3, 3.0, -2.5"

APPLy:USER

[SOURce:]APPLy:USER [<frequency>[,<amplitude>[,<offset>]]] is used to output the arbitrary waveform currently selected by the FUNC:USER command. The waveform is output using the specified frequency, amplitude and dc offset.

Comments • See “Arbitrary Waveforms” on page 46. for more information on creating and downloading user-defined arbitrary waveforms to non-volatile memory.

APPLy?

[SOURce:]APPLy? is used to query the function generator's present configuration and return a quoted string.

Comments • The function, frequency, amplitude and offset voltage are returned as shown in the sample string below (the quotation marks are returned as part of the string):

"SIN +5.000000000000E+03,+3.000000E+00,-2.500000E+00"
