200-7125 MHz Attenuator Assemblies for Automated Testing at 0-95dB by 1dB steps

Four new models have been added to the JFW website.  These attenuator assemblies operate at 200-7125 MHz with attenuation range 0-95dB by 1dB steps.  All of these models feature Ethernet remote control that can be used with scripts for automated testing. 50BA-056-95:    1 attenuator in benchtop chassis 50BA-057-95:    2 attenuators in benchtop chassis […]

When Choosing Test Equipment, Don’t Forget the Interface

By: Paul Pickering When purchasing RF test equipment, such as an RF switch or a programmable attenuator, it’s tempting to concentrate on specifications such as insertion loss, frequency range or VSWR. But implementing a complex testing scheme usually involves integrating multiple pieces of equipment from multiple manufacturers. A customer will often purchase the first piece […]

Handover Test Systems Reach 8 GHz For Wi-Fi 6E and 5G Applications

In order to remain competitive and offer the latest in high-speed services, cellular hardware and Internet-of-Things (IoT) device manufacturers and system operators are moving to higher frequencies now available with Wi-Fi 6E (5.925 GHz to 7.125 GHz) and mid-band 5G (sub-6 GHz). Moreover, these latest devices now operate in a wider variety of network topologies […]

75 Ohm Matrix Switches for Automated Lab Testing

JFW has added two new 75 Ohm matrix switches to our website model listings.  One model is “blocking” type and the other is “non-blocking” type.  Blocking matrix designs are constructed with RF switches on both halves of the matrix.  Non-blocking matrix designs use power dividers on the input half of the matrix and RF switches […]

New 8X8 Non-blocking Matrix Switch | 350-6000MHz

JFW model 50MS-426 is a 50 Ohm 8X8 non-blocking matrix switch operating 350-6000MHz.  Each input port can be connected to multiple outputs simultaneously.  Each output port can be connected to only one input port.  It is remotely controlled via Ethernet or RS-232 connection.  The IP settings can be manually set via the front panel display.  […]

New fixed IP Address for JFW’s Ethernet Test Box

The fixed IP address of our Ethernet Test Box is now 104.63.176.50 (tcp port 3001). If you have been testing our your software with our test box, you will have to update to use 104.63.176.50 (port 3001). The test box is running our latest generation Ethernet/Serial firmware.  You can make an Ethernet connection to the […]
