Applications of the N1918A
Power Analysis Manager
The N1918A Power Analysis Manager
is a suite of application toos that
comprises a basic version which
comes with the purchase of the U2000
Series, and an advanced version,
Option 100, which is an optional,
licensed software. The technical data
sheet for the N1918A describes the
differences in the performance and
capabilities for the two versions in
detail. The following applications are
intended to provide the measurement
engineer with power requirement
information in order to check if the
statistical routines, data archiving
provisions, and manipulation
information are suffi cient. Figure 17
provides an overview of the different
capabilities.
Data Gathering Function
The N1918A Power Analysis Manager is a multi-faceted software application,
running on Windows operating systems, which multiplies the measurement and
diagnostic power of a user’s power data collection. In its simplest confi guration,
it gathers power measurement data from three typical sources, as shown in
Figure 17: the N1911/12A P-Series Power Meter, the N8262A P-Series Modular
Power Meter and the U2000 Series USB Power Sensor.
All the data that is provided is formatted on the basis of the Standard Commands
for Programmable Instrumentation (SCPI). SCPI defi nes a uniform and consistent
language for the control of test and measurement equipment, and the transfer
of data.

The transfer of data can be done through any of these three data and
control buses; USB, GPIB or LAN connectivity, which are generally available on
most modern power meters.

Figure 17 The N1918A Power Analysis Manager interfaces with power
measurement data from various sources, two power meters as
shown, plus the U2000 Series.
