OML Introduces an Electronic Attenutation Source Module

OML Expands Source Module to Include Option for Electronic Attenuation

November 21, 2014. OML introduces a new option for its signal generator frequency extension module, SxxMS. Already available with options for manual adjustable attenuation and DC power connection to Keysight's PSG; the source module now includes an option for electronic attenutation. The SxxMS Series will expand your existing microwave Signal Generator capabilites to conduct measurements from 50 to 500 GHz. Easily connected to the output of a signal generator this module enables high performance for your DUT. Characterize the DUT with the confidence that it will produce accurate results with superior performance of output power, spurious and harmonics.

Now with the option of electronic attenuation you can master your power with this module by controlling the attenuation through a DC voltage or through Keysight's PSG with option UNT.  Power leveling and power flatness can now be achieved through simple computer control.  This option comes in various attenutation values which are: option -EA1 that adds 0 to 20 dB typical adjustable attenuator to the RF path, -EA2 that adds 0 to 40 dB typical and -EA3 that adds 0 to 60 dB typical.

This option is currently available in waveguide bands from 50 GHz to 110 GHz; above 110 GHz contact factor; model number SxxMS-EA. Videos are available detailing the installation and operation procedure for the electronic source module.
