LAG-65 AUDIO SIGNAL GENERATOR
This instument is an innovation in audio generators. The range from 11 to 110,000 cps is covered in 4 decades. Each decade has 10 steps and a fine frequency adjuster. The generated frequency is read on the calibrated meter scale. The output voltage is determined by the output voltmeter reading and attenuator setting. The voltmeter has auxiliary scales calibrated in decibels, where 0 dB=1 volt, and the range from -60 dB to +20dB, or 1 millivolt to 10 volts, so that the output level may be easily read. This feature is very useful for rapidly obtaining the characteristics of amplifiers and filter networks. The frequency meter covers the range from 10 to 110,000 cps in 4 bands. It may be used independently by connection to an external source for the determination of the frequencies of oscillators, horn, audio beats, etc.
The LAG-65 is a compact generator which should be in every audio and supersonic laboratory and workshop for development, testing and checking.

LAG-55 AUDIO GENERATOR
The LEADER Model LAG-55 is an indispensable instrument for checking, testing and maintenance of audio amplifiers, speakers, etc. Three different waveforms, namely, sine, square and complex, are available. The wide frequency range, 20 to 200,000 cps, calibrated on a clear dial, and the constant output level, are very desirable features which have been incorporated in the generator. The sine wave output with very low harmonic content is suited for the determination of distortion in high fidelity amplifiers. The square wave output is used for observing the transient characteristics of amplifiers, networks, filters, etc. The complex wave output of two combined frequencies, a low (line) and a high (5,000 to 8,000 cps) with an amplitude ratio of 4 : 1 is used for I-M distortion testing. The internal high pass filter and an external scope are used. Instructions are supplied.

LMA-1000 HETERODYNE MARKER ADDER
The LMA-1000 is most useful device when used in combination with the LSW-321 and the LSG-301 described above for receiver alignment. It is possible to "mark" the calibrating frequencies on the resonance curves at all points, even in the trap circuits without disappearance. This is done without distorting or overloading the circuits under test. The marker signal does not pass through the receiver. Alignment will be more accurate because the pip amplitude can be varied independently of the swept frequencies. The instrument is specially designed for use with the LEADER LSW-321 and LSG-301, and is highly recommended.
