  • Page 13: Chapter 1 Introduction

    Chapter 1 Introduction The Model 4391M is a multi-purpose Radio Frequency wattmeter designed around a microcomputer. A program stored in permanent memory controls the operation of the instrument at all times, permitting the detection and correction of various error sources and the refinement of the raw data produced by the directional detectors.

  • Page 14: Description

    At each end of the line section are Bird Quick-Change type RF connectors which may be easily interchanged with any other Bird QC connector. See Bird Catalog for types available. Operating power is derived from either rechargeable nickel-...

  • Page 15: Chapter 2 Theory Of Operation

    Chapter 2 Theory of Operation Figure 2 is a block diagram of the major functional parts of Description of the Model 4391M RF Wattmeter. The Microcomputer Operation integrated circuit shown, controls all the other portions of the instrument, which fall into two major groups. The keyboard and range switches serve only to pass Keyboard, information to the computer.
  • Page 16 Bird Model 4391M Power Analyst Each reading output by the display is derived from up to three voltage readings using the circuitry described above. Once these voltages are measured, all remaining operations are performed within the computer chip as follows: The voltages are corrected for error due to dc drift in the analog circuitry.
  • Page 17 Theory of Operation The electrical values of the element circuits are carefully balanced and designed so that current from the reverse wave will cancel the other almost completely. The result is directivity always higher than 25 dB, which means that the element is highly insensitive (nulled) to the REVERSE direction wave.

  • Page 19: Chapter 3 Installation

    Chapter 3 Installation The Model 4391M RF Power Analyst is completely portable and very suitable for field or laboratory use. Its power is derived from either rechargeable nickel-metal hydride (NiMH) batteries for SN 074100063 and above, or rechargeable nickel-cadmium (NiCAD) batteries for SN 074100062 and below inside the unit, It can also be powered from a 115/230 VAC power source connected to the unit through the power cord supplied with the unit.

    Bird Model 4391M Power Analyst The Model 4391M contains a short section of rigid 50 ohm Connections coaxial air dielectric transmission line. To make measurements relating to the travelling waves in a coaxial line, that line must be disconnected at some convenient point to permit the Model 4391M air line to be inserted.
  • Page 21 Installation “REFLECTED” and is normally pointed in the direction opposite to forward power flow. The elements are clamped in place by the hold-down catches on the face of the line section. These catches must be used to avoid error due to the element not contacting the bottom or seating plate of the socket.

    The Model 4391M arrives at values of CW power by a method quite different from analog meters such as the Model 43, also manufactured by Bird Electronic. While the two instruments will agree when the measured wave is of constant amplitude, AM or SSB waves will result in different indications (in the CW mode).
