Agilent / HP / Keysight 8780A
8780A Vector Signal Generator, 10 MHz to 3 GHz
Description
This unit 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 700MHz of output modulation.
The vector signal generator' wideband modulation is complemented with an unmodulated coherent carrier output for demodulation of test signals.
It 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.
