Cable Calibration
Follow the directions in the LMF application program to calibrate
cables.
– Calibrate the short cable (see Figure 3-13) and two 10 dB
attenuators to establish a baseline and then calibrate the TX and RX
set–ups. Because at least 40 dB of attenuation is needed when
testing the FER, the set–up for RX is the same as for TX.
