Frequency Meter AN/USM-29
    Frequency meter AN/USM-29 is designed for precise generation or measurement of frequencies in the range of 15 kc through 30 mc. Output frequencies generated by the frequency meter are controlled by eight dials arranged on a decade basis. The value set up on the dials is the frequency generated by the equipment. The generated signal is accurate to within .0001 percent of the value selected on the dials.
    When measuring a signal of unknown frequency, the AN/USM-29 compares the unknown frequency against the accurate, known frequency it is generating. It presents the results of the comparison both aurally and visually by means of headphones, an indicating meter, and a cathode ray tube.

ME-6D/U ELECTRONIC MULTIMETER - FUNCTIONAL DESCRIPTION:
A portable test instrument with a wide range of applications. This equipment is a highly sensitive vacuum tube voltmeter which accurately measures ac voltages. It also serves as a flat, high-gain, wideband amplifier. A single panel meter is calibrated in ac volts and decibels. Meter readings are substantially independent of variations in line voltage, tube aging, and replacement of circuit components.
RELATIONSHIP TO SIMILAR EQUIPMENT:
This model differs radically from previous models of the ME-6/U. It is neither mechanically nor electrically interchangeable.
TECHNICAL DESCRIPTION:
Circuit Information: The circuit consists of a multistage amplifier terminated by electron tube type diodes connected in a bridge circuit. A panel mounted meter indicates rectified current. The meter is designed with sloped pole pieces so that indications are proportional to the log of the rectified current. The rectified current is accurately proportional to the input voltage of the working range of the instrument. Stability of the amplifier gain is achieved by feeding back amplified voltage to part of the input circuit. A jack is provided for inserting a telephone plug when the set is used as a high-gain amplifier.
Pwr Supply: 117 volts, ac, 50 to 400 cycles per second, single-phase
Freq Range: 15 cycles per second to 250 kilocycles per second
Voltage Range: 500 microvolts to 500 volts, ac, in 6 steps; 0.005, 0.05, 5, 50, 500 volts, rms
Meter Scale: ac Voltage: 0.5 to 5 volts
Decibels: -5 to +17 (based on 0 decibel = 0.001 watt in 600 ohms)
Rectifier Voltage: 250 volts, dc (approximately)
