The Agilent 8780A vector signal generator is a synthesized IF source
with exceptional modulation for modern receiver and component testing.
It is capable of modulation bandwidths almost 100 times wider than
previous synthesizers. It has built-in mapping to simplify generation
of common digital modulation formats. Its extra-wide modulation bandwidth comes from a vector modulator that effectively doubles
baseband modulation bandwidths for 700 MHz of output modulation. The
vector signal generator' wideband modulation is complemented with an unmodulated coherent carrier output for demodulation of test signals. The Agilent 8780A vector signal generator offers a wide variety of modulation using both digital and analog inputs. It generates many
standard digital modulation formats like QPSK and 16 QAM and
traditional modulation like FM, AM, and pulse. By combining the
different modulation types, signals as diverse as Barker-coded radar
pulses and Doppler-shifted satellite signals can be simulated. The
Agilent 8780A vector signal generator is well suited for receiver
measurements where wideband or complex modulations are required. It can
be used as a calibrated transmitter to test modern radar EW receivers or communication receivers using vector I/Q modulation techniques. It
provides a stable, coherent carrier for pulse measurement. It can also
be upconverted if receivers operate at frequencies higher than 3 GHz.
