Conclusions The measurements of parameters at 70 MCs 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 MCs 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. Author
