Keysight Technologies (Agilent HP) AGILENT 70900B Local Oscillator, MMS

The HP 70900B is the master control module, 2/8-width module for 70000 Modular Measurement System (MMS) spectrum analyzers. It is also a component of the lightwave signal analyzers. It can control the following slave modules: HP 70902A and 70903A IF sections; HP 70904A, 70905A1B, 70906A1B, 70908A sections; HP 70907A and 70907B external mixer interface module; HP 70300A and 70301A traclring generators; HP 70620A, 70620B and 70621A preamplifiers; HP 70700A high speed digitizer; and HP 70310A precision frequency reference and HP 70810B lightwave section. The HP 70900B LO has two main functions in the HP 70000 spectrum analyzers: as the synthesized local oscillator (LO) and as the master control module for the system. As a spectrum analyzer local oscillator, it affects phase noise, stability, and frequency accuracy. The HP 70900B is the reason that the analyzer has excellent phase noise performance of -108 dBdHz at 10 kHz offset from the carrier. 300 MHz calibrator output, BNC (f), 50 ohm (nominal), Output power: -10 dBm ± 0.3 dB, Frequency accuracy: 300 MHz x frequency reference accuracy. Sweep output/lnput: SMB (m), rear panel, 0-10 V for sweep >= 50 ms, Accuracy: 2%. Tune + span output: SMB (m). rear panel. 4.5-9.9 V (1 .5 V/GHz).
