HP 85629B Test and Adjustment Module

When attached to the spectrum analyzer’s rear panel, the HP 85629B Test and Adjustment Module (TAM) p rovides diagnostic functions for the HP 8560A. Because the TAM connects directly to the analyzer’s internal data and address bus, it controls the analyzer’s hardware directly. It would be impossible to control the hardware to the same extent either from the analyzer’s front panel or over the HP-IB.

The TAM measures voltages at key points in the circuitry and flags a failure whenever the voltage falls outside the limits. The TAM locates the failure to a small functional area which can be examined manually.
