Scalar network analyser

The latest product by ELAD is a 'black box' except for the connectors. All controls and display is handled via the computer, connected via USB 2.0. This is not only cost wise a good solution, but offers many more possibilities like printing, archiving, mobile use etc.

Like a traditional network analyser, the SNA-2550 measure transmission and reflection from 400kHz to 2500MHz in five ranges. Output level is adjustable between -50 and 0dBm, the dynamic range is 60dB. The input attenuator can be adjustend from 0 to 50dB in 10dB steps. A semi-rigid coax cable is supplied for automatic calibration of the device.

The SNA-2550 power (12-15V) is supplied over the included USB cable.

The user interface on the PC is similar to a traditional network analyser. All measurements and settings can be stored and later recalled. Windows 2000™, Windows XP™, Vista or Windows 7 32/64bit is required.

SMA Male/Female Adaptor

All RF connectors wear with use. The RF Explorer SMA ports are subject to minimal wear each time the connector interface is coupled and de-coupled with an antenna, a SMA cable, an attenuator or a RF device of any kind. If you repeat plug/unplug operations over the RF Explorer SMA port hundreds of times, the SMA port may underperform over time and exhibit undesired attenuation.

To protect the SMA port for frequent plug/unplug operations, you can use this adaptor and keep it directly attached to the RF Explorer port. Then you plug/unplug other RF devices into this adaptor, not the original SMA port. After hundreds of operations, if the adaptor wear and show attenuation or reliability problems, you can just replace it by a new one and always keep your original RF Explorer SMA port intact.
