Test Systems from JFW Industries

 
Test Systems
 
Over 30 years ago, JFW began designing and delivering custom RF test systems without charging NRE’s. Today, JFW is still beating the competition by offering RF test systems that are custom designed for your application without charging NRE’s. JFW has designed and built RF test systems as simple as a single Ethernet controlled programmable attenuator and as complex as a 48 x 96 non-blocking RF matrix switch. 
JFW has manufactured many different types of test systems with various RF and control options which has evolved into
our current line of catalog RF test systems. JFW has also created our own test systems catalog in order to show our
designing and manufacturing capabilities. Whether it is a custom model or one of our catalog models, JFW has your RF
test system needs covered.
 
  Quick ROM (rough order of magnitude) pricing for custom test systems provided in 1-2 days typically.
  Custom designed RF test system without NRE charges.
  Full line of existing RF test systems for easy selection.
  Engineering staff (317-887-1340, jfwengr@jfwindustries.com) that is directly available to answer questions.
  Multiple remote control interfaces (Ethernet, RS-232, GPIB, IEEE-488, TTL)
  Manual control options (keypad w/ LCD, toggle switches, rotary switches, momentary switches)
  Various RF connectors available (BNC, TNC, SMA, N, 7/16, Reverse Polarity TNC, Precision F)
 
Programmable Attenuator Assemblies
Whether you call it a digital attenuator, step attenuator, or programmable attenuator, JFW has a wide selection of variable attenuators that we can use to manufacture a remotely controlled attenuator assembly for you.  JFW can take any of our catalog programmable attenuator models (solid-state or electro-mechanical) and integrate it with remote and manual control.  We have three sortable tables that list our online programmable attenuator models by enclosure type:  19 inch rack, Benchtop, or Mini Benchtop. Our Benchtop models are AC powered w/ an internal AC/DC power supply. The Mini Benchtop models are DC powered and are shipped w/ an AC/DC wall transformer.

RF Switch Assemblies
JFW can take any of our catalog RF switches (solid-state or electro-mechanical) and integrate it with remote and
manual control. We have a sortable table that lists all of our online models or you can email our test system engineers
(jfwengr@jfwindustries.com) your specific requirements.

RF Matrix Switches
Whether you need a blocking or non-blocking matrix switch, JFW has a wide selection of RF switches and power
splitters/combiners to construct a RF matrix switch to meet your requirements. Jump to our sortable table of online RF
matrix switch models or email our test system engineers (jfwengr@jfwindustries.com) your specific requirements.

RF Transceiver Test Systems
If you are testing a device that can transmit and receive (i.e. radios), then our RF transceiver test systems are what you
need for quick automated testing of radio communication in simulated environments. JFW offers two types of
transceiver test systems: standard RF transceiver system (full fan-out, every RF path has a programmable attenuator)
and the RF cloud version (each input port has a single programmable attenuator). Jump to our sortable table for
example block diagrams of both system types and our listing of online models.

Handover Test Systems
Whether you are fading multiple base station signals to a handset, or testing multiple communication standards with a
handset, JFW has a handover test system to help automate your RF testing. JFW offers two types of handover test
systems: standard handover system (full fan-out, every RF path has a programmable attenuator) and the LC handover
test system (each input port has a single programmable attenuator). Jump to our sortable table for example block
diagrams of both system types and our listing of online models.

Manual Handover Test Systems
When RF testing is done in a RF shielded test room, JFW’s manual handover test systems are a perfect solution. It
allows for easy attenuation of different communication standards to a handheld device using only passive RF
components. Jump to our sortable table for example block diagrams and our listing of online models.

Custom Models
Most of JFW’s test system business involves custom designed models for specific testing applications. JFW does not
charge NRE’s for custom models. JFW prides itself in being able to provide custom test system solutions with pricing
that is in-line with our catalog test systems. We encourage you to email us your specific requirements
(sales@jfwindustries.com). We will respond with a ROM (rough order of magnitude) quote in 1-2 days.

Do you already have an idea of the RF functionality you require, but are not sure about which RF components are
needed?  Let our experienced engineering staff help design a test system for your testing needs. JFW’s test system
engineers (jfwengr@jfwindustries.com) have been working with customers around the world to design and deliver RF
test systems for over 30 years.
