B & W 410 Distortion Meter

Designed as a companion instrument for the Model 210 Audio Oscillator, this distortion meter measures audio distortion, noise level, audio gain or loss in decibels, and ac voltages. Measurements are read directly on the front panel meter. It is a useful device for measurements for FCC proof-of-performance tests.

Ailtech F370A Audio Sine Generator

This equipment, with a high output level of 5 watts, is ideał for obtaining accurate gain and frequency response measurements, as a voltage source for distortion testing, and as an all-around test device for the broadcaster. It covers a frequency span of 20 Hz to 20 kHz in three decades through a modified Wien bridge oscillator, ensuring Iow distortion output. Output power may be inserted into resistive loads of 50, 200, 600, and 5,000 ohms.

Fluke 1980A Frequency Counter

The 1980A VHF/UHF Frequency Counter may be opera-ted from standard linę voltage, or from an optional 12-volt dc battery pack. Its rangę is from 5 Hz to 50 MHz (direct input) and from 25 MHz to 515 MHz (prescaled input). A variable trigger level control on the direct input helps eliminale erroneous readings due to sine waves with noise spikes or ringing square waves. Readout is automatically displayed on a 6-digit LED display. The 1980A is an invaluable tool for accurate frequency determination of all types of laboratory devices, transmitters, exciters, oscilla-tors, and any type of communication equipment.

Ailtech F380A Audio Sine Generator

Designed especially for precision and dependability required by professional audio and broadcast personnel, the F380A features ultra-low distortion through its rangę of 20 Hz and 20 kHz: Distortion is less than 0.1%. Three separate output attenuators permit reduction of the oscillator level in 0.1 dB steps to a maximum of 111 dB. Output is ±15 dBm into impedances of 50, 150, and 600 ohms. It is ideał for FM exciters, transmitters, amplifier response, and sound reinforcement and distribution systems.

Fluke 8000A Digital Muhimeter

Pushbutton control practically eliminates operational error with the 8000A. There are 26 different ranges, including five ranges of ac and dc voltage, five ranges of ac and dc current, and six ranges of resistance. Ranges include: ac voltage — 199.9 mV to 1199 V; dc voltage — ±199.9 mV to ±1199 V; ac current — 199 pA to 1999 mA; dc current — ±199.9 mV to ±1999 mA; resistance — 199.9 ohms to 19.99 megohms. Values are read directly on an LED display.
