Cable Calibration
Follow the directions in the WinLMF program to calibrate cables.
– Calibrate the short cable (see Figure 6-12 or Figure 6-14) and two
10 dB pads to get a base line and then calibrate the TX and RX
setup. Since you need at least 40 dB of loss when doing the FER
test, the setup for RX is the same as TX.
ATP Setup
TX Path Calibration setup is shown in Test Equipment Setup (see
Figure 6-19 through Figure 6-22).
