1. Does not include the effect of the cable set on the test ports.
2. Excludes roll-off below 500 MHz, which is typically −18 dB at 100 MHz, and −25 dB at
50 MHz.
3. Measurement Conditions: normalized to a thru, measured with two shorts, 10 Hz IF
bandwidth, averaging factor of 8, alternate mode, source power set to the lesser of maximum
power out or the maximum receiver power.
4. Limited by noise floor.
