Model GA101x Series High Power E-H Tuner

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.

However, predicting which plunger to operate first or the effect each

plunger will have on producing an impedance match is nearly

impossible without the aid of additional impedance analysis

equipment. Thus, choosing which plunger to adjust at any point

during the tuning procedure is often a matter of either trial and error

or prior experience with a given load.

CAUTION:

Care must be taken to avoid operating the

microwave generator at power levels exceeding the rating of the

tuner. Excessive power levels can cause damage to the tuning

plungers.

A recommended tuning procedure for first-time matching of a given

load is as follows:

1. Slowly adjust one plunger in either direction while monitoring the

level of reflected power. If reflected power increases while

adjusting in one direction then reverse directions and continue

adjusting until the reflected power stops decreasing.

2. Repeat step 1 for the other plunger.

3. Return to the plunger adjusted first and re-adjust in whichever

direction causes reflected power to decrease. Continue

adjusting until reflected power stops decreasing.

4. Repeat step 3 while alternating between plungers until reflected

power no longer decreases by adjusting either plunger. Make

note of the plunger positions and the level of reflected power.

5. Return both plungers to the original positions and repeat the

process except to start with a different plunger. Continue until

reflected power has again been minimized and make note of the

plunger positions and reflected power level. Compare to the

results obtained in step 4 and then adjust the plungers to the

positions which gave the best results.
