Power Sensor/Meter with USB Interface –
Connect Directly to a PC
ST series power sensors are
complete miniature power
meters. The sensors contain a
CPU that controls the sensor,
processes the measurement
results and operates the
interface. All measurement data
and settings can be transmitted
via a USB interface to and from
a PC. This gives the concept of
using a PC as the user interface
in classic microwave power
measurement.
Connecting a sensor directly to a
PC is the most cost-effective
method for high-precision power
measurements, especially if a
PC is used already for data
acquisition and evaluation. This
is commonly the case in
production environments that
include a process controller.
Omitting the display unit saves
space in the rack and reduces
costs.
The ST Series has the ability
have multiple sensor heads
connected to the PC and
operated simultaneously. An
added advantage to the
production user Service
technicians too will also
appreciate this product since the
power sensor is only 1.9 x 1.2 x
6.7 inches 34x 43 x 125mm and
can easily be operated from a
laptop. Satori currently plan to
use the ST Series with a PDA as
a controller to improve usability
for the I&M Market.
The Power Meter is controlled
using the Satori software loaded
on a PC. It can be used with
windows XP operating system.
This Software is powerful and
flexible but easy to use. This is a
virtual power meter with basic
measurement functions for the
PC workstation.
A software toolkit is supplied to
control the power sensors via the
PC. This toolkit is supplied as
standard with every ST sensor. It
includes a DLL (dynamic link
library) for individualized use of
the entire sensor functionality
with Windows and the user
Interface.
