    <h1>Anritsu MG369XB Synthesizer</h1>
    <h2>Introduction</h2>
    <p class="body">
      This instrument driver provides programming support for <em>Anritsu MG369XB Synthesizer</em>.
      It contains functions for opening, configuring, taking
      measurements from, and closing the instrument.
    </p>
    <h2>Assumptions</h2>
    <p class="body">
      To successfully use this module, the following conditions must be met:
    </p>
    <p class="body"><em>For GPIB instrument drivers:</em></p>
    <ul>
      <li>
        the instrument is connected to the GPIB.
      </li>
      <li>
        the GPIB address supplied to the initialize function
        must match the GPIB address of the instrument.
      </li>
    </ul>
    <p class="body"><em>For VXI instrument drivers:</em></p>
    <ul>
      <li>
        the instrument is installed in the VXI mainframe and you are
        using one of the following controller options:
        <ul class="list-circle">
          <li>Embedded controller</li>
          <li>MXI</li>
          <li>MXI2</li>
          <li>GPIB-VXI</li>
        </ul>
      </li>
      <li>
         the logical address supplied to the initialize function must
         match the logical address of the instrument.
      </li>
    </ul>
    <p class="body"><em>For RS-232 instrument drivers:</em></p>
    <ul>
      <li>
        the instrument is connected to the RS-232 interface.
      </li>
      <li>
        the COM port, baud rate, parity, and timeout supplied to the
        initialize function must match the settings of the instrument.
      </li>
    </ul>
    <h2>Error and Status Information</h2>
    <p class="body">
      Each function in this instrument driver returns a status code that
      either indicates success or describes an error or warning condition.
      Your program should examine the status code from each call to an
      instrument driver function to determine if an error occurred.
      The general meaning of the status code is as follows:
    </p>
    <table summary="Organization of error codes">
      <tr><td class="tablehead">Value</td><td class="tablehead">Meaning</td> </tr>
      <tr><td>0</td>              <td>Success</td> </tr>
      <tr><td>Positive Values</td><td>Warnings</td></tr>
      <tr><td>Negative Values</td><td>Errors</td>  </tr>
    </table>
    <p class="body">
      The description of each instrument driver function lists possible error
      codes and their meanings.
    </p>
