Coaxial Phase Shifters - Stepper Motor Driven

Stepper Motor Driven Phase Shifters

ATM's Stepper Option offers finer phase adjustment when compared to any other form of automated shaft control. 

With a resolution of less than 0.02° phase shift per step @ 1 GHz (or less than 0.35° phase shift per step @ 18GHz) this option offers the most accuracy when controlling one of ATM's phaseshifters. 

ATM's stepper motor driven products require the use of a PC, and controllers such as ATM's stepper motor controller model MCMS-003

STEPPER MOTOR
ATM's 2-phase stepper motor drive can easily be programmed to Increase Phase, or Decrease Phase. 180 RPM max suggested directly coupled to any ATM device in order to prevent damage.  Suggested Input Power is 24 to 48 VDC.  1.5A (ATM supplies a 24 VDC Power supply when the MCSM-003 is ordered).  An internal encoder standard on all models allows finer traceability.  See connector pinout for details.

MOTOR CONTROL CONNECTORS
Units are mounted with male 9-pin D-subminiature (DE-9M) connector for stepper motor power/control.  Refer to D-sub pinout diagram for detail.

RF CONNECTORS
Per phaseshifter model selected; SMA, Type-N, or Type-K (2.92mm)

CONSTRUCTION
Milled aluminum, Chem-film finish.

The USB drive will come loaded with the following items:
Along with your your stepper motorized phase shifter, there will be the following items inside the box:
  1. ATM test program--this is a short program that should be used to verify that you have installed the software correctly, and that everything is appropriately connected.
  2. General Instruction--this will walk you through how to install the control software, as well as how to run the ATM test program.
  3. Command Instruction--This outlines how to lay out your own program.  This also illustrates the basic instructions you need to know in order to write your own proram.
  4. Connection Diagram--This will illustrate how to make the appropriate connections between the PC, Power supply, and Stepper Motor driven unit using the cables provided (See below for Connection Diagram)
  5. IMS Terminal--The software used to control the stepper motor.  This will come in a 32 bit and 64 bit version.
