Singer fm-10 500MHZ signal generator/service monitor
Singer Gertsch FM-10 Signal Generator/Frequency Monitor
Comes with what you see in the pictures. If you don't see it, you probably wont get it.
Specifications are from Singer and for a FM-10C not an FM-10 plain! Because of this, specifications may vary slightly due to upgrades, options or revisions this unit may or may not have.
The unit was checked out and it is does function. We do have a power cord for it as well. The unit is uncalibrated. There are some scratches and dents that will not affect performance on the unit.
The Oscilloscope Deviation Monitor Module's Serial Tag Reads:
The FM-10C is a direct synthesizer. The output signal of the frequency synthesizer consists of various frequencies which are derived from the 10 MHz TXCO crystal oscillator by a process of frequency division and multiplication. These frequency elements are mixed, filtered, and amplified to produce the output signal. Harmonic oscillators and phase lock loops of the indirect synthesizer are eliminated by this method. The residual FM which can result from a loop closure technique is completely eliminated. All of the frequencies which represent the decade elements are selected by the decade switches. Each frequency is instantly available at the output.
Each step in the mixing process is filtered to minimize the spurious responses which are close to the desired frequency.
The internal signal which supplies the reference for the frequency meter also functions as an extremely accurate signal generator source.
Precise audio signals may also be generated through a special adaptation of the beat-note circuitry and are available at the front panel.
Oscilloscope Deviation Monitor Module, Model ODM-1 General Description:
The ODM-1 plug-in module derives its operating power and signal input from the mainframe via the rear connector, P1. It contains its own power switch to permit use of the mainframe while the plug-in is switched off. High voltage power supplies for the CRT are also developed within the module. There are four subassemblies in the ODM-1: 2 MHz IF board, A1, high voltage power supply board, A2, vertical amplifier board, A3, and horizontal amplifier board, A4. The circuitry contained in the ODM-1 may be divided into six sections: operate and overload lamp circuitry, horizontal deflection circuitry, internal modulation circuitry and power supply circuitry.
