GENERAL DESCRIPTION. The Spectrum Analyzer TS-1379A/U is a sensitive, high resolution test instrument of the automatic scanning, superheterodyne receiver type. The primary application is in testing Single Side Band (SSB) transmitters and receivers for measurement of third order distortion of the transmitted or received signal. 
    The Spectrum Analyzer permits analysis of one or many signals simultaneously, Each signal within the band scanned (sweep width) is displayed on the CRT element as one of a series of "pips". The pip amplitude indicates the signal level. The pip position along the horizontal axis indicates the signal frequency. 
    Any one of six parts of the RF band - the "Band Scanned" - within the 2mc - 30mc range of the Analyzer may be selected by means of the Band Selector tunable oscillator, and the "Scanning Width" may be selected by the Sweep Width Selector. The Sweep Width Selector positions provide eight different degrees of frequency separation of the signal display. A preset operating mode automatically adjusts Sweep Width, Gain, Resolution, and Scanning Rate at each one of the Sweep Width positions. 
    The Band Selector tunable oscillator is a high stability continuous tuning signal generator designed to provide local injection signals over the frequency range of 2. 5mc to 30mc. It is a fully transistorized, precision, variable capacitor tuned oscillator. The 0. 3 volts rms output signal is the first local oscillator in the heterodyne system. The tunable oscillator is free from spurious signals, hum and noise are suppressed at least 60db below signal level. The unit is particularly suitable for use in intermodulation testing. 
   The Spectrum Analyzer is also valuable for monitoring a frequency band for the appearance of or disappearance of and shift of signals. A display of frequency distribution can be obtained by selecting the Sweep Width, bringing the "Scanned Band" into the narrowest position (150cps) to enable examination of signals so closely adjacent in frequency that their corresponding "pips" normally are merged together. At this reduced Sweep Width (150cps) signals with an amplitude ratio of 60db separated by 50cps are clearly indicated. One of the internal self-checking features, the Internal Dual Frequency RF Test, simulates such a test.

Used with TS-1379A
Transistorized two-tone IF Signal Generator for testing SSB equipment. Has two 20 - 20Khz audio oscillators and two independent IF oscillators. IF outputs 497.5, 498.5, 501.5, or 502.5Khz . Output levels 2-2.5 V into 600 ohms (AF); 1-1.25 V into 60 ohms (IF) with attenuation to 100 db in 1 or 10 db steps. The AF and IF signal outputs are independent of each other. Generates two separate AF signals which can be used independently, one at a time, or both can be added for simultaneous use. It also generates four different, unmodulated IF signals which are available independently, one at a time, or in specific pairs simultaneously. Available from www.fairradio.com

OCT-2 (cabinet) and OCT-3 (rack mount) are a 1947 contract. There was an earlier OCT with a different design before this model. It is used to monitor FSK shift in RTTY transmitters. It is basically a superhet receiver with two limiters and a discriminator whose output is supplied to a VTVM which indicates the amount of frequency shift. The audio output (phones) comes from the discriminator to aid in tuning, so it is essentially an FM receiver, not useful for AM or CW.
