  • Page 5: General Description

    SECTION 2.0 GENERAL DESCRIPTION The Instruments For Industry, Inc. ( IFI ) manufactured SMX100 Wide Band Amplifier is a Bench Top or rack mount amplifier providing 100 Watts of RF power from 10 kHz to 1000 MHz. The SMX100 incorporates two frequency bands of operation identified as Band 1 and Band 2 which provides the operator easy frequency band switching without changing the RF Output connections.

  • Page 6: Ac Connection And Set-Up

    2.1 AC Connection and Set-Up If your amplifier is equipped with a MS Connector for a power connection, the following instructions will assist a qualified technician to wire the supplied mating MS Connector. Determine whether your amplifier is Single Phase or Three Phase by locating the Serial Number Label and noting the Phase (PH) identification.

  • Page 7: Warranty Information

    This warranty is the full extent of obligation and liability assumed by IFI with respect to any and all IFI products. IFI neither makes, nor authorizes any person to make, any other guarantee or warranty concerning IFI Products.

    RF Relays to the Band 1 PA and Driver section which in then to the output. With the SMX100 in the High Band ( BAND 2 ) mode of operation, the input signal is directed by RF Relays to the Band 2 PA and Driver section which in then to the output.

  • Page 21: Level Control Board

    5.3.1 Automatic Level Control (Option) In this mode, the SMX100 serves as the voltage comparator and variable gain stage. It will enable the maintenance of a constant RF voltage vs. frequency at the input to an imperfect load or a virtually constant E-Field at a measurement point in space.

  • Page 22: Automatic Leveling Control (Alc )

    SECTION 6.0 AUTOMATIC LEVELING CONTROL (Optional) 6.1 ALC FEATURES The Automatic Leveling Control ( ALC ) switch located on the front panel has three positions, 'INT', 'OFF' and 'EXT'. Described below are the features of each position Important Note: Figures 5.0 and 6.0 indicates the display for a typical amplifier and the ALC option is indicated however if the amplifier is not equipped with this option, the ALC option will not be displayed.

  • Page 23: Leveling Using The "Int' Mode

    6.1.3 The 'EXT' or External Position The SMX100 serves as the voltage comparator and variable gain stage. It will enable the maintaining of a constant RF voltage vs. frequency at the input to an imperfect load or a virtually constant E-Field at a measurement point in space.

  • Page 24: Leveling Using The 'Ext' Mode

    Connect the ALC on the rear panel to the detected output port on the remote detector. Connect the remote detector in series with the SMX100 output and at the input to the load. The system is now ready for operation. Amplitude adjustments can be made with the level control as in manual operation.
  • Page 25 The Test Set-Up Procedure, refer to Figure 8.0 for a Typical ‘E’ Field Leveling set-up 1) Connect the RF Output of the Signal Generator to the RF Input of the SMX100. 2) Connect the RF Output of the SMX100, located on the same panel as the RF Input connector, to the antenna.

    6) The system is now ready to be tested with a swept analog or stepped frequency input signal. All IFI component blocks shown in Figure 8.0 are capable of operating continuously from 10 kHz to 220 MHz. Extended frequency coverage, over the full range of the unit, can be provided by substituting an EFS-5 for the EFS-1 and adding a second log periodic or ridged horn antenna.
