4 Channel Wideband DC Load

Simulation of active antennas for the test of modern multimedia components. The slot-in module PT-4CL is a 4-channel DC current load, suitable for the frequency range 100 kHz…8500 MHz to simulate DC loads of active antennas. Each current load can be set via an external resistor. PT-4CL represents an economic alternative against the programmable PT-4CS DC sink.

4 Channel BIAS-T Current Up To 400 mA


The operation bandwidth extends from 100 kHz up to 8500 MHz. Thereby the slot-in module is suitable for the test of components of all common broadcast, cellular radio and wireless standards.


The programmable DC current load PT-4CL enables the simulation of active antennas in test applications. Each current sink can be set via an external resistor. By the wide current and voltage range, active antennas in different executions and properties can be simulated. 

Compact module design

The rugged module design of the PT-4CL is designated for the integration into the SR6-11C System platform. Up to 10 PT-4CL modules
(40 DC current loads) can be integrated into one SR6-11C System. The module PT-4CL can be combined with other slot-in modules in the SR6-11C system platform. The voltage supply of the modules occurs by the internal power supply of the system platform without the requirement of additional cabling. The modular concept enables quick and easy maintenance (MTTR) by the changing modules.
