Operation
The vector signal analyzer provides for all signal processing, display and
analysis. With the exception of scalar analysis, all 89410A features are available
in the wideband vector signal analyzer system.
The example program only needs to provide control over center frequency,
input attenuation, spectral mirroring and system calibration. As a convenience,
it also initializes both instruments for wideband vector signal analysis. This
includes, but is not limited to, changing instrument modes, setting inputs to DC
coupling and adjusting RBW settings. The example program also lets you
initiate the MMS self-calibration routines.

The upper trace shows
the spectrum of a 10
Mb/s QPSK signal
measured using the
wideband vector signal
analyzer system. The
trace is 20 MHz wide.
The lower trace is an eye

signal obtained using the
HP 89410A vector
modulation analysis
(Option AYA).
