Agilent / HP / Keysight 8657D
8657D Pi/4 DQPSK Signal Generator for NADC & PDC
Description
This signal generator adds Pi/4 DQPSK digital modulation capability to conventional AM, FM, and pulse modulation formats.
It builds on the excellent performance of the Agilent 8657 signal generator by adding digital modulation capability.
It provides the performance to test mobiles for North American Digital Cellular (NADC) and Japanese Digital Cellular (PDC) radio systems.
