Applications

The HP 5350B/5351B/5352B series are precision frequency counters that were widely used in RF and microwave test laboratories, telecommunications facilities, broadcast stations, and electronics service benches from the 1970s through the 1990s. These instruments measure frequency, period, time interval, and totalize pulses with high accuracy and were essential tools for technicians working with signal generators, oscillators, transmitters, and other RF equipment. The 5350B series represents the mid-range of HP's frequency counter lineup — reliable, accurate instruments designed for both production testing and field service environments. This service manual remains invaluable for anyone maintaining or restoring these instruments, providing the detailed technical information required to troubleshoot circuit problems, verify calibration, replace components, and restore units to working condition. Period-correct service documentation like this is essential for legacy equipment restoration and is increasingly difficult to locate.
