Abstract : Conclusions: The measurements of parameters at 70 MC/s according to SCS-135A and Modification No. 7 can be accomplished. The systematic error involved in measurement results was clarified and a correlation established. The fabrication of the 70 MC/s units is critical as to the technique required to 'finish' the crystal units to frequency. The measurement of frequency and resistance deviation over the operating temperature range -55 to +90C can be adequately and economically done if a coil is used in series with the crystal unit.
