Adding Real-Time Noise to a Dual ARB Waveform
A vector signal generator with option 403 enables you to apply additive white gaussian noise (AWGN)
to a carrier in real time while the modulating waveform plays in the dual ARB waveform player.
Figure 9-1 Real Time I/Q Baseband AWGN Softkeys
For the selected carrier to noise ratio,
the bandwidth over which the noise is
integrated.
The amount of noise power relative to
the carrier power.
For details on each key, use key help
as described on page 23.
The state of the noise (on or off)
is shown on the display.
The actual noise bandwidth, which is
typically slightly wider than the carrier
bandwidth.
