Step Notes
1[RF IN Loss]
2 Enter the RF In loss using the
numeric keypad. Enter a
negative number to indicate a
gain.
If you are using a cable and attenuator
connected to the base station power
amplifier, enter the combined cable and
attenuator RF In loss here. The RF In loss
can be obtained by measuring the Insertion
loss. See “Two Port Insertion Loss” on
page 123.
If you are using an external preamp and
need to make an allowance for the preamp’s
gain, enter the gain by using a negative
number.
Example of a loss: if you have to account for
an external attenuation of 20 dB, enter
“20 dB” here.
Example of a gain: if your preamp has a
gain of 12 dB, enter the negative figure
“–12 dB” here.
Note: If data had been previously entered in
[RF IN Loss], that data will be lost and
replaced by the value you enter here.
