Introduction
The 2-port transmission measurement option provides the capability to perform 2-port measurements. This measurement is used to verify the performance of tower mounted amplifiers, duplexers, and also to verify antenna isolation between two sectors. The excellent dynamic range makes it suitable for repeaters as well.
Both high and low power settings are available. The High Power setting delivers approximately 0 dBm power at the RF out port, ideal for antenna isolation measurements and duplexers. When making measurements of a Tower Mounted Amplifier, it is recommended to use the low power setting (approximately –30 dBm). This will ensure that the RF In port is not over powered and that the measurements are made in the linear region of the amplifier.
The integrated 32V bias tee (Option 10) enables users to turn on up to 32V on the center conductor of the RF In port.
