二手 Agilent-Keysight 8782B 在 玛丽湖, 佛罗里达, 美国

Vector Signal Generator
The Agilent HP 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 in either parallel or serial. The Agilent HP 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 HP 11846B pi/4 DQPSK I-Q generator (sold separately) can also be used to drive the analog I and Q inputs for testing North American dual mode digital cellular radio receivers. 50 MHz...
