The DAT60KU Compact RFAttenuator
The DAT60KU is a stand-alone
wide-band digital attenuator
instrument rated for 1 – 18GHz anduseful in an extended range
beyond 22GHz. Attenuation range
varies from 0 to 60 dB with a
0.50dB minimum step size.
Insertion loss is between 12dB and20dB. The DAT 60KU is a dualcontrol device, attenuation setting
can be accomplished both by theuser interface OR via USB port
serial commands.

Remote Operation
Industry standard SCPI
commands allow the DAT60KU
to be controlled by any hostsystem with a USB interface.
The USB port is configured asa virtual COM port allowing user
software to access theDAT60KU as if it were astandard serial COM device
without any additional drivers.
