Description
General Description
Mesh network test equipments allow simultaneous interconnection of different devices or test systems. The test equipment effectively operates as a mesh network with independently variable attenuation on every path. This allows emulation of a “real-world” mesh network in the confined space of a production environment. Path loss can be varied independently between any pair of devices and even any pair of ports of the devices – emulating the effects of transmission distance and potential interference, without affecting any other paths.
Product Description
MTS-063-06-24-UE-S High Resolution Mesh Network Test System is a highly accurate, bidirectional, 50 Ohm digitally controlled step attenuator. It provides calibrated attenuation from 50 to 6000 MHz with an attenuation resolution of 1 dB. It also offers a features an attenuation accuracy less than 1 dB over 63 dB of control range. The attenuators are easily programmable for fixed attenuation, swept attenuation ramps and fading profiles directly from either Ethernet or USB interfaces. MTS-063-06-24-UE-S allows all devices to communicate to each other in a test environment by independently varying path loss between any pair of devices and emulates different signal strengths, transmission distances and potential obstacles. Its low default insertion loss (when the attenuation is set to 0 dB) allows to operate at a desirable dynamic range suitable for low power applications as well as mid- and high-power applications.
