Tutorial
Creating Arbitrary Waveforms (Option 002)
Arbitrary waveforms are optionally available with the 33210A (Option 002). To
NOTE
upgrade your 33210A to include arbitrary waveform functionality, go to
www.keysight.com/find/33210U.
The Keysight 33210A allows you to create custom arbitrary waveforms of up to
8 K points (8,192 points), and provides five built-in examples of arbitrary
waveforms. You can create an arbitrary waveform from the front panel, or you can
use the Keysight IntuiLink software provided on the CD-ROM included with the
Keysight 33210A. The Keysight IntuiLink software allows you to create arbitrary
waveforms using a graphical user interface on your PC, and then download them
into the Keysight 33210A. You can also capture waveforms from your Keysight
oscilloscope and import them into IntuiLink. Please see the online help included
with the Keysight IntuiLink software for further information.
For most applications, it is not necessary to create an arbitrary waveform with a
specific number of points since the function generator will repeat points (or
interpolate) as necessary to fill waveform memory. For example, if you specify 100
points, each waveform point will be repeated an average of 8,192 / 100 or 81.92
times. For the 33210A, you do not have to change the length of the waveform to
change its output frequency. All you have to do is create a waveform of any length
and then adjust the function generator's output frequency. However, in order to
get the best results (and minimize voltage quantization errors), it is recommended
that you use the full amplitude range of the waveform DAC.
When entering waveform points from the function generator's front panel, you are
not required to enter the points at evenly-spaced intervals in time. You can always
add additional points as needed where the waveform is more complex. From the
front panel only, you can also use linear interpolation to smooth the transition
between waveform points. These features make it possible to create useful
arbitrary waveforms using a relatively small number of points.
With the 33210A, you can output an arbitrary waveform to an upper frequency
limit of 3 MHz. However, note that the useful upper limit is usually less due to the
function generator's bandwidth limitation and aliasing. Waveform frequency
components above the function generator's bandwidth will be attenuated.
