QATT-7G

Programmable 4-Channel Step Attenuator

QATT-7G offers four independent attenuator channels in 50 ohms technology. Due the wide operation frequency range from 100 kHz up to 7000 MHz the device is also suitable in applications in conjunction with the 5G (FR1) standard. The device can be local controlled or remote controlled via LAN and USB interface. An integrated web interface allows an easy remote control without the effort of programming.

Attenuation range 0 ... 95.25 dB


The step attenuators in QATT-7G are based on wear-free semiconductor switches. They are settable in 0.25 dB steps independent for each channel.  

Synchronous Operation

Via the TRIGGER IO interface of the device preloaded attenuator values are taken synchronous with a fed in trigger pulse. The rapid adoption of the attenuation values takes place via the hardware in the microsecond range.
In master mode the device generates a trigger pulse. This allows the attenuation settings of other devices to be synchronized in the network. 

Compact Design

QATT-7G has a 19“ design for the integration into 19“ system racks. As well QATT-7G is suitable as table top device for laboratory use.

Applications

For the test of cellular devices, components for wireless communication as infotainment components, field propagation scenarios can be emulated reproducible in laboratories. Applications of QATT-7G are in the range of product development, validation, quality assurance and in production.
