Determining long-term stability (aging)
Communications systems and network elements are subjected to a wide variety of environmental
influences which adversely affect component performance to a greater or lesser degree. If the effect
of such influences on, say, system gain are to be recorded, the PCM-40 provides support for this
application. During system line-up, the results and instrument configuration are stored so that they
can easily be recalled. In the subsequent measurement, the results are displayed within the tolerance
mask and the new result trace is superimposed. The instrument then determines the difference
between the two measurements so that the deviation can be seen directly.
Status of connected test signal
The PCM-40 continuously monitors the connected test signal during the measurement and dis-
plays the result on the front panel and in detail on the screen. This keeps you informed of the status
and prevents incorrect interpretation of the measurement results.
Storage of measurement configurations
The test equipment settings required for routine or specialized manually-performed measure-
ments, along with explanatory comments, can simply be stored by the PCM-40. The number of
setups which can be stored is limited only by the system resources of the computer you are using.
