Hp agilent 8657D/H01 1024 mhz am/fm modulation sig gen
HP Agilent 8657D/H01 1024 MHz AM/FM Modulation Sig Gen
Powers up, output frequency and power looked good.
AM/FM modulation checked good, does not include the Pi/4 DQPSK modulator.
Makes for a great general purpose 100 Khz to 1024 MHz AM/FM/ Pulse modulated (external mod) signal generator.
The 8657D Pi/4 DQPSK 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 8657B synthesized signal generator, adding the digital modulation capability needed to test the most recent cellular radios for the North American Digital Cellular (NADC) and the Japanese Digital Cellular (JDC) radio systems. The 8657D offers exceptional analog modulation, good spectral purity, and superb output level performance.
* 100 kHz to 1030 MHz AM & FM
* Pi/4 DQPSK for NADC and JDC
- 1420 to 1540 MHz data inverted
* <4% error vector magnitude
* Option H01 - Pi/4 DQPSK Digital Pulse Modulation. Baseband Pi/4 DQPSK I and Q signals
