General Safety:
SWR TRUE should only be used for its intended purpose and never be
connected to cables carrying hazardous voltages.
When handling NiMh batteries great care should be observed preventing
polarity reversal and short circuit as the batteries may explode or catch fire.
General Information.
Description:
The SWR TRUE instrument is an Antenna Analyzer for analyzing Antennas
and feeder cable VSWR or Return loss. The instrument measure the return
loss by using a Wheatstone RF bridge, a detector and a RF Generator. The
control of the entire instrument is by a microprocessor. The microprocessor
is running in a MOP (Micro Operating Program) environment. The MOP
schedule and execute all tasks required to handle the LCD Screen, the Key-
board, The RF generator, USB interface, serial interface, time of day clock
and measurement calculations.
The RF generator covers the frequency range from 30 MHz to 2700 MHz by
using two PLL generator covering 650 MHz to 1450 MHz and 1450 MHz to
2700 MHz. The low frequency range from 30 MHz to 650 MHz is covered by
mixing the two PLL generators.
The instrument has a built in time of day clock. This clock is used to identify
the output files going to either USB or serial interface.
The XML Data option, this option will allow the user to enter specific data
into the instrument regarding Operator name, Location of Object, Type of
Object. The feature will have an XML file viewer or the data could be used in
all PC programs supporting XML data format ( Microsoft, LINUX etc.)
Remote Control, this option will allow the instrument to be controlled by the
RS232 serial interface. The setup going to the instrument and the measure-
ment data coming from the instrument can be a part of a large test system.
