Use the Arbitrary Function Generator
Use the Arbitrary Function Generator
The MDO3000 contains an optional integrated arbitrary function generator (AFG) (option MDO3AFG). This is useful for
simulating signals within a design or adding noise to signals to perform margin testing.
The function generator provides output of prede fi ned waveforms up to 50 MHz. Choose between sine, square, pulse,
ramp/triangle, DC, noise, sin(x)/x (Sinc), Gaussian, Lorentz, exponential rise/fall, Haversine and cardiac signals.
The AFG can generate up to 131,072 points of an arbitrary waveform. You can create the waveform from any of the four
internal ARB memories, the four (or two) analog channels, the four (or two) reference waveforms, the math waveform or the
16 digital channel waveforms. You can also use a .CSV (spreadsheet)
fi le stored externally or a prede fi ned template.
You can modify your arbitrary waveform via an on-screen editor and then replicate it out of the generator. For more involved
waveform manipulation, you can use Tektronix’ ArbExpress PC-based waveform creation and editing software. It is available
for free download from www.tektronix.com/software. Use version 3.1 or later with the MDO3000.
How to access the AFG
To access the AFG output, connect your cable
to the port marked
AFG OUT in the back of the
oscilloscope.
To see the output of the AFG, connect the other
end of the cable to one of the input channels on
the front of the oscilloscope.
Push the front-panel AFG button to turn the
AFG output on and off.
The button lights up when the output is on. The
light goes out when it is off. The On-Off status is
always off when you recall an instrument setup.
The AFG will always come up in the off state
when you turn the oscilloscope power on.
