to enter the frequency menu; select [Start Freq] menu, then use the numeric keys,
knob or arrow keys to input the start frequency value and select the corresponding unit menu to complete
the input; the frequency in this example is set to 1MHz.
4. Similar to step 3, set the stop frequency needed by the measurement; the frequency in this example is set
to 4GHz.
5. According to the Section 3.1 in this Chapter, calibrate at port 1 of the instrument;
6. After the Port 1 is calibrated, connect the measured cable to the Tester and link match load to other end
of the cable, as shown in Figure 3.8. The Tester will display the measured return loss curve.

to turn on marker function, so that you can check the return loss conditions of the cable
at each frequency. For example, under the frequency of 2,100MHz, return loss of the cable is 32.05;
SVWR is 1.05, as shown in Figure 3.9.
