Report on Test of RCA Victor Company Test Oscillator Model TMV-97-A - Serial No. 785 Range 150 to 25000 Kilocycles

Conclusions: The output of subject oscillator, with respect to wave form is considered satisfactory, with good control of attenuation. The maximum output at frequencies from150 to1460 kilocycles is considered sufficient for ordinary servicing purposes, and while the output is greatly diminished at higher frequencies, the lowest being 168 microvolts at 14300 kilocycles., it is believed this oscillator would be useful as a readily portable servicing instrument, for such purposes as the limitations of the equipment permit. No provision is made in the instrument for determining the magnitude of the output. Typical calibration curves only are furnished with the equipment, and it is necessary to make individual curves for each instrument. However, due to the lack of temperature control or other provision for accurate frequency setting, the frequency stability of this instrument is not considered adequate for lining up the i-f stages in the Models RAA and RAB without reference to a suitable frequency standard.
