Adding Real–Time Noise to a Signal for N5172B/82B with Option 403 and 653/655/656/657
Adding Real-Time Noise (AWGN) to a Dual ARB Waveform

For details on each key, use key help
as described on page56.
The state of the noise (on or off)
is shown on the display.
Figure 11-6 on page328
provides additional details on
these settings.
This is the stand–alone Real–
Time AWGN and the 2nd page of
the Modulation Mode menu (see
Static graphic representation of
ARB Real–Noise AWGN (i.e.
graphic does not update as
values change).
The relationship of the values are displayed in the
static graphic of ARB Real–Time AWGN.
The Total Noise Power is the Noise Power over the
occupied noise bandwidth (NBW * 1.25).

For the selected carrier to noise ratio,
the bandwidth over which the noise is
integrated. Typically, Carrier
Bandwidth (CBW) is the occupied
bandwidth of the carrier.
Flat Noise Bandwidth (NBW): The
actual flat noise bandwidth (NBW),
which should be slightly wider than
the carrier bandwidth (typically 1.6
times wider). The occupied
bandwidth is =
(1.25 * the Flat Noise Bandwidth)
see page327
The Carrier Bit Rate softkey sets the
carrier bit rate. (The default carrier bit
rate is 1 bps.)
The Carrier Bit Rate softkey is only
available when the Carrier to Noise
