  • Remarques
  • The new hp805 Slotted Line incorporates a radically new structural design with precision manufacture, resulting in an instrument of unvarying accuracy for the measurement of microwave circuits.
    This new instrument employs two parallel planes and a rigid central conductor in place of the conventional co-axial arrangement. This configuration has several important advantages over the standard slotted section.
    For example, it permits the parallel planes to be made mechanically rigid; thus insuring greater accuracy and providing a rigid probe carriage. The central conductor is proportionately larger and more rigid, with less tendency to bow. Depth of probe penetration is inherently less critical, and therefore carriage inaccuracies are minimized. Leakage is also low because the effective slot opening is small. This new design permits VSWR of the basic section to be held to less than 1.02.
    In the construction of the hp805 Slotted Line, every effort has been made to achieve complete mechanical stability. The flat sections or planes are of cast, normalized aluminum alloy, ribbed to combine strength and light weight. The central conductor is a selected brass rod, centerless ground and silver plated.

    CALIBRATION
    Calibration of the scale is in millimeters and centimeters, and the probe position can be read to 0.1 millimeters. The probe carriage traverses the slot length on ball bearings, and is free-moving to facilitate quick setting of the probe position. Close setting is made by means of a vernier control knob. The probe circuit is tunable over the instrument's entire frequency range, 500 to 4,000 megacycles. Depth of probe penetration can be quickly and easily adjusted by means of a knob on top of the probe carriage.
    The 805 Slotted Line is supplied complete with a specially designed steel-and-dural carrying case. The case includes sponge rubber shock-mountings to guard the instrument against damage, and is fitted with steel snap fastenings and carrying handle.

    SPECIFICATIONS
    Frequency Range: 500 mc to 4,000 mc (minimum frequency determined by usable length of 171/2 inches).
    Characteristic Impedance: 50 ohms. (For use with such flexible coaxial cables as RG: 8/U, 9/U, 10/U, 14/U, 17/U, 18/U, 21/U.
    Connections: TYPE N. (One male; one female). Special fittings designed to mate with Type N connectors provide a minimum VSWR. Connectors compensated so that either end may be connected to the load. Also included are shorting connectors, male and female, for use in making phase measurements.
    Residual VSWR: 1.04. Slope: Negligible.
    Calibration: Metric, calibrated in cm and mm. Vernier permits reading to 0.1 mm.
    Detector: Circuit. tunable, uses standard crystal (1N21B or 1N23) ; Sperry Barretter Model 821; or 1/100 ampere instrument fuse.
