提出了一种阵列侧向测井仪信号发送、接收设备的设计方案．在发送设备中采用ＭＣＳ５１单片机技术来产生六个频率不同、相位严格保持一致的发送信号．文章给出了阵列侧向测井仪信号发送设备原理方框图．针对信号接收的特点，笔者讨论了在接收设备中采用高共模抑制比、带有动态零点补偿的测量放大器抑制共模干扰；采用同步数字堆栈技术（即同步数字叠加技术）抵抗随机干扰、提高信噪比；采用数字滤波器进一步减小无用信号；采用ＦＦＴ技术测出各种频率点的幅值，从而计算各地层的电阻率的问题．
A design scheme of array side-to-side logging tool signal transmitting and receiving equipment is proposed. In the sending device using MCS51 single-chip technology to produce six different frequencies, the phase strictly consistent to send the signal. The article gives a schematic block diagram of the array side-to-side logging tool signaling device. For the characteristics of signal reception, the author discusses the use of high common-mode rejection ratio in the receiving device, with a dynamic zero-compensation measurement amplifier to suppress common-mode interference; using synchronous digital stacking technology (ie, synchronous digital overlay technology) to resist random interference, improve Signal to noise ratio; the use of digital filters to further reduce the useless signal; using FFT technology to measure the amplitude of various frequency points, in order to calculate the resistivity of the formation.
