Agilent Technologies E1441A PULSe:DCYCle?, SWEep:SPACing?, SWEep:TIME?, Parameters

50% for square waves.

•Possible Conflict with Output Frequency: The duty cycle is auto- matically 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 generated and the duty cycle is adjusted.

PULSe:DCYCle?

[SOURce:]PULSe:DCYCle? [MINMAX] queries the duty cycle setting. Returns a value in percent.

SWEep:SPACing

[SOURce:]SWEep:SPACing LINearLOGarithmic selects linear or logarithmic spacing for the sweep. The default is Linear. [ Stored in volatile memory ]

SWEep:SPACing?

[SOURce:]SWEep:SPACing? queries the sweep mode. Returns “LIN” or “LOG”.

SWEep:TIME

[SOURce:]SWEep:TIME <time>MINMAX sets the number of seconds required to sweep from the start frequency to the stop frequency. Select from 1 ms to 500 seconds. The default is 1 second. MIN = 1 ms. MAX = 500 seconds. The sweep time setting is stored in volatile memory.

Parameters

Parameter Name	Parameter Type	Range of Values	Default Units
time	numeric	1 ms to 500 sec	seconds

Comments • The number of frequency points in the sweep depends on the sweep time you select and is automatically calculated by the function generator.

SWEep:TIME?

[SOURce:]SWEep:TIME? [MINMAX] queries the sweep time. Returns a value with units of seconds.
