QuinStar Technology offers Motorized Rotary Vane Phase Shifters in all
waveguide bands from 18.0 to 110 GHz. The QMP series is a motorized, computer controllable
version of QuinStar’s standard Direct Reading Phase Shifter and provides a 0 to 360º
phase shift range with 0.5 degree resolution.
The phase shifter
is controlled by a precision stepping motor and all control and driver electronics are
packaged within the phase shifter housing. Microprocessor-based electronics translates the
desired phase shifter setting into the required motor position and provides the proper
drive signals to the motor. Motor speed is variable to ensure accurate positioning and
smooth operation. |
The Phase Shifter can be controlled remotely through an IEEE-488 interface or
manually with a front panel control. A three-digit readout on the front panel displays the
setting. The product requires a 24-volt, 500 mA power supply.
The QMP series
motorized direct reading phase shifters are used in automated RF measurement systems. They
are frequently used in RF substitution type test arrangements for precise measurement of
phase characteristics including bridge circuits and phase networks. |
