Product User Manual Page 6 Model GA101x Series High Power E-H Tuner INSTALLATION Preliminary Inspection Upon arrival at the installation site the tuner should be thoroughly inspected for damage or wear caused during shipping. Any visible damage to the packaging material or the tuner itself should be noted and reported immediately to the shipping company in accordance with standard claims procedures. -
Page 7: Flange Alignment Pins
Each waveguide flange connection that uses a quick-release clamp requires two alignment pins for proper alignment of the adjacent waveguide sections. All GAE waveguide components include one alignment pin for each flange designed for use with quick-release clamps. Alignment pins can be installed into either of two threaded holes centered above and below the waveguide broadwalls. -
Page 8: Operation
Product User Manual Page 8 Model GA101x Series High Power E-H Tuner OPERATION Basic Operation The most common intended function of the high power E-H tuners is to provide an impedance match to the process load. Operating the tuner for this purpose is a procedure involving the adjustment of either or both tuning plungers while monitoring power reflected from the process load. -
Page 9: False Null
Product User Manual Page 9 Model GA101x Series High Power E-H Tuner False Null The above procedure can sometimes lead to a false indication of reflected power minimization. That is, it may appear that adjusting either plunger will result in an increase of reflected power. This “false null”... -
Page 10: Maintenance And Calibration
Although the GA101x series tuners are very rugged and stable devices, they can be subject to damage due to excessive power levels or mishandling. If damage occurs, the circulator should be returned to GAE for repair. Contact GAE for information on repair services. © 2002-2003 Gerling Applied Engineering, Inc.
