• Model: Q-Standard - Inductor 513A - Boonton Radio Corp.; Boonton,

• Notes
• The Q-Standard Type 513-A is a shielded reference inductor which has accurately-measured and highly-stable inductance and Q characteristics. Specifically designed for use with Q-Meters Type 260-A and 160-A, the Q-Standard is particularly useful as a check on the overall operation and accuracy of these instruments, as well as for providing precisely-known supplementary Q-circuit inductance desirable for many impedance measurements by the parallel method.
  The Q-Standard consists of a specially-designed, high-Q coil of Litz wire, wound on a low-loss Steatite form. The coil is hermetically sealed inside a copper shield can which is filled with inert gas under pressure. The desired Q-versus-frequency characteristics are provided by a carbon film resistor shunted across the coil. Two replaceable banana plug connectors mounted on the base serve to connect the unit to the Q-meter circuit.
  The Q-Standard is supplied in a convenient wooden carrying and storage case. Each unit is individually calibrated and marked with its true inductance (L), distributed capacity (Cd), effective Qe and indicated Qi at 0.5, 1.0 and 1.5 Mc, respectively. Tolerance: L ±1%, Cd ±2%, Qe ±3%, measured at 73°F. Any instrument deviating more than ± 7% from the marked value is not operating in accordance with original specifications.
