Applications
The HP 70311A and 70312A are clock source modules designed for use within Hewlett-Packard's 70000 Series Modular Measurement System — a mainframe-based, modular RF and microwave test platform widely used in signal analysis, spectrum analysis, and signal generation applications during the late 1980s and early 1990s. Clock source modules within the MMS provide the precise reference timing and frequency standards that other modules in the mainframe rely on for coherent, phase-locked operation. This manual covers the operating procedures, front-panel controls, and calibration routines needed to set up, verify, and maintain the 70311A and 70312A modules to HP's factory specifications. It is an essential reference for technicians performing periodic calibration, troubleshooting, or repair on HP 70000 Series systems still in service, as well as for collectors and metrology labs maintaining legacy HP MMS equipment.
This HP 70311A / 70312A Clock Source Operating & Calibration Manual (part no. 70311-90000) is in good used condition. The spiral binding is intact, and the pages are clean and fully legible. The cover shows light shelf wear consistent with age — minor scuffing and a small mark on the front — but no tears, water damage, or missing pages are visible.
