ISWFT performs radio frequency (RF) and optical transmission line
performance verification and diagnostics.
The Harris Improved Swept Frequency
Tester (ISFWT) is a portable, battery
powered, transmission line test set,
designed specifically for flight line and
shipborne transmission line performance
verification, fault detection and fault
isolation. Test functions include automatic
and manual insertion loss, return loss,
voltage standing wave ratio and distance
to fault measurements. The ISWFT design
adopts proven advanced concepts of the
extremely successful AN/PLM-4 Radar
Signal Simulator, which is currently in use
worldwide.
TRANSMISSION LINE TEST AND
DIAGNOSTICS
ISWFT is a robust RF transmission line
analyzer that provides precise transmission
line measurements for test and diagnostic
purposes. A precision RF interface is
utilized between the ISWFT and the Unit
Under Test (UUT) improving the accuracy
of the ISWFT for test and diagnostics. The
ISWFT is supplied with extremely low-loss
RF cables and adapters, along with builtin automated calibration routines that
minimize measurement errors and provide
test repeatability.
FEATURES
Small, lightweight, one-man portable – 1
cubic ft., approximately 25 lbs. (11.3 kg)
Powered by two hot swappable Lithium
Ion batteries
IMPROVED SWEPT
FREQUENCY TESTER (ISWFT)
USER INTERFACE
Improved dynamic range over similar
transmission line test sets
Frequency Range: 10MHz-20GHz, with
options to 40 GHz
Operating Modes: Automatic and manual
Comprehensive Built-In-Test (BIT)
- Automatic self test at turn-on
- Includes auto alignment of auxiliary
external devices as necessary
The integrated user interface is a sunlight
readable touch-screen display running
Windows-based software and allows
operator interaction based on common
interface practices that are familiar
to most users. The interface gives the
operator access to automate tests that
run customer-created scripts, providing
easy-to-use and repeatable testing
of complex systems along with direct
feedback as testing is performed. Access
is also provided to manual testing, giving
the user the ability to trace and repair
failures when they are detected, without
any additional test equipment. Test files
and associated test setup parameters are
uploaded to the ISWFT via a removable
storage device. Transmission line test
results are downloaded on the same
removable storage device for archive and
display to the operator. The ISFWT user
interface software contains onboard test
procedures, cable and cable segment data
library, test archive files, exportable .csv
data files for Excel or other applications
for plot and display of test results and a
robust operator help file.
- Provides continuous status monitoring
to detect internal ISWFT faults
Sunlight readable display
Menu driven operator interface
Optional Optical Time Domain
Reflectometry (OTDR)
- Optical OTDR Frequency Range:
1-2 GHz
