Standard
Waveforms
Previous paragraphs provided sinusoidal waveform examples,
showing how to set amplitude and offset. This section expands on
that capability, covering all nine standard waveforms in the 3152B
internal library: sine, triangle, square, pulse, ramp, Gaussian
pulses, exponential pulses, DC, and noise.
The following command sequence example demonstrates how to
select a standard ramp waveform with an amplitude of 1Vp-p, an
offset of zero, a rise time of 10% of the ramp period, and a fall time
of 10% of the ramp period:
*rst
Restores factory defaults.
outp 1
Activates the hardware connection to
the front panel OUTPUT connector
and turns the output on.
func:mode fix
Selects the built-in library of standard
waveforms.
func:shap ramp
Selects the ramp from the built-in
library as the active waveform.
ramp:tran 10
Programs the ramp leading edge rise
time in units of percent (referenced to
the ramp period).
ramp:tran:tra 10
Programs the ramp trailing edge fall
time in units of percent (referenced to
the ramp period).
volt 1
Sets the amplitude level to 1Vp-p.
volt:offs 0
Sets the offset level to zero.
Similar sequences could select different standard waveforms and
program their parameters. See Chapter
5 for programming
references for the complete range of standard waveforms.
Using the Apply
Command
The Apply command provides shortcuts for setting up a waveform
and its parameters without programming each parameter
individually. This also selects the waveform as the active signal at
the output connector. It does not, however, eliminate the need for
turning on the output. You may use the Apply command on a
waveform from the built-in library or on waveform segments that are
pre-loaded to the waveform memory. Sequenced and modulated
waveforms do not use the Apply command.
The following example uses the Apply command to specify a
square wave at the end of the programming sequence:
*rst
Restores factory defaults.
appl:squ 10.7e6,2,1,30
Selects the standard square wave as
the active function, and simultaneously
