2.Position the cursor at Start Frequency in MHz and select it. Enter a value for the start of the frequency sweep from 0.4 MHz to

1000 MHz or 1700 MHz to 2000 MHz.

3.Position the cursor at Stop frequency in MHZ and select it. Enter a value from 0.4 MHz to 1000 MHz or 1700 MHz to 2000 MHz. This value should be larger than the start frequency and in the same frequency band.

4.Position the cursor at Plot scale in dB/div and select it. A Choices menu appears. The available choices are 1, 5 or 10.

5.Position the cursor at Maximum Expected Gain in dB and select it. Enter a value in the range of − 50 to +40 dB. This parameter sets the expected worst case power for the ANT IN port. It is very important to overestimate the expected gain to avoid damage to the ANT IN port. This parameter also determines plot resolution by setting the upper limit.
