SY/T 5585.1-1993 Test method of electrical parameters of seismic data transmission cable Characteristic impedance and propagation time test (English Version)
This standard specifies the test methods for the electrical parameters of seismic data transmission cables - characteristic impedance and propagation time. This standard is suitable for measuring the characteristic impedance and propagation time of manufactured length seismic data transmission cables using network analysis method, resonance method, pulse method, and open and short circuit method.
