<strong>Automatic</strong> <strong>Impedance</strong> <strong>Matching</strong> <strong>System</strong>, <strong>WR340</strong>The <strong>GA1022</strong> <strong>Automatic</strong> <strong>Impedance</strong> <strong>Matching</strong> <strong>System</strong> integrates a highpower vector impedance analyzer and motorized 3-stub waveguide tunerin a single compact waveguide component for use in industrialmicrowave heating applications. Designed for CW, high-ripple (“rectified”)and pulsed microwave power operation modes, the <strong>GA1022</strong> measuresboth magnitude and phase of reflection coefficient as well as incident,reflected and absorbed power and frequency, then utilizes thatinformation to automatically control the tuner to rapidly optimize theimpedance match. The <strong>GA1022</strong> is available with Windows® basedsoftware for effective monitoring and recording of impedancemeasurements, and it can operate either autonomously without anexternal controller or by remote control from a personal computer viaRS232 or optional CAN or DeviceNet interface.The optional control, visualization and data logging software significantlyexpands the system capabilities. Basic features include:♦ Microsoft Windows® environment♦♦♦♦♦♦♦♦♦Accurate measurement of complex reflection coefficient and itsdisplaying in various formats, including- Magnitude and Phase angle- Return Loss and VSWR- Polar displays of Smith (Z and Y) and Rieke-type ChartsGERLING<strong>Model</strong> <strong>GA1022</strong>Measurement of incident, reflected, and absorbed power and display in various formats, including Watts, decibels,percentage of incident powerNumerical readout of signal frequency, load reflection coefficient and power in various formatsArbitrary shifting of the measurement reference planeSaving measured data as tables (text files) or pictures (BMP, GIF, JPG)Periodic data logging of all or some of the measured quantitiesMultiple windows enabling simultaneous observation of various quantities in different formatsWide selection of appearances of displayed curvesStoring and retrieving of complete system settings matched to particular tasksElectrical Specifications:FrequencyMaximum PowerMinimum PowerDynamic RangeMeasurement ErrorWaveformMax CW RippleRectified modePulse modeInput VoltageControl InterfaceTuning AccuracyTime to optimal match2425-2475 MHz30 kW (continuous and peak)1 W20 dB maximumReflection coefficient: .05 max.Incident power: 5% max.Standard: CW, rectifiedOptional: pulsed15% of peak value400 pps maximum100 us minimum pulse width100 ms maximum pulse period24 V + 10% DC, 625 mARS-232As low as 1% reflection(depends on characteristics ofmicrowave generator and load)0.5 to 6 seconds (depends oninitial load mismatch)Mechanical Specifications:WaveguideFlangeElectrical ConnectionsConstructionWeightOverall DimensionsOperating Temperature<strong>WR340</strong> (RG113/U)CPR-F (UG554/U)9-pin male D-subAluminum waveguide13 lbs (6 kgm)(see outline drawing)40 ºF (5 ºC) to 130 ºF (55 ºC)Options:1.
