– TRIGger[:STARt:]SOURce selects the sample source. SINusoid requires that
TRIGger[:STARt:]SOURce INTernal1 be selected.
– The [SOURce:]FREQuency[1] or [SOURce:]FREQuency2 subsystems specify
the signal frequency for
RAMP, SINusoid, SQUare, and TRIangle waveforms.
They specify the sample rate for arbitrary (
USER) waveforms.
• When [SOURce:]FUNCtion[:SHAPe] RAMP or TRIangle is selected, the greater of
the
SOURce:RAMP:POINts value and 8 points of contiguous waveform segment
memory must be available. When
[SOURce:]FUNCtion[:SHAPe] SQUare is
selected, 8 points of contiguous waveform segment memory must be available.
Attempting to select one of these functions with less contiguous waveform segment
memory available, or to set
[SOURce]:RAMP:POINts to a value larger than the largest
contiguous amount of available waveform segment memory when ramp or triangle
wave output is selected, will generate Error +1000,"Out of memory".

FUNC SQU Selects square wave mode.
:USER
[SOURce:]FUNCtion:USER <name> selects which one of the 128 possible stored
segment sequences the Agilent E1445A generates when arbitrary waveform
generation is selected by
[SOURce:]FUNCtion[:SHAPe] USER.
