Keysight (Agilent) 8782B
1-250MHz Vector Signal Generator
BPSK, QPSK, 8PSK, 16QAM, 64QAM, 256QAM, 9PRS, 25PRS, 49PRS and 81PRS digital modulation, pulse, vector and scalarArbitrary vector modulation with bandwidths up to 100 MHz (200 MHz typical)Simulates impairments such as quadrature error
The Agilent 8782B vector signal generator is designed to test digital microwave and RF receivers. It is a 1 MHz to 250 MHz synthesized signal generator with a wide range of digital modulations, as well as vector (analog I and Q), pulse and scalar (AM) modulation.
A vector (I/Q) modulator is built-in. The analog I (In-phase) and Q (Quadrature-phase) inputs allow for arbitrary phase and magnitude modulation, while digitally-coded information can be applied to the digital inputs either in parallel or serial.
The Agilent 8782B has a built-in pseudo random bit sequence (PRBS) generator making digital modulation from BPSK to 256QAM possible without using external digital data sources.
The Agilent 11846B pi/4 DQPSK I-Q generator can also be used to drive the analog I and Q inputs for testing North American dual mode digital cellular radio receivers.
50 MHz analog I and Q inputs , typically DC to 100 MHz, drive the vector modulator directly to control the magnitude and phase of the generator output. This allows you to generate arbitrary magnitude and phase modulation with bandwidths up to 100 MHz.
