14
Determine the maximum value and the minimum value of the
calculated Power Linearity at the various settings and record them in
the Test Record as "Maximum Power Linearity at current setting", and
"Minimum Power Linearity at current setting", respectively.
15 Subtract the minimum power linearity value from the maximum power
linearity value and record the result as the Tota l Po we r Li ne ar ity.
Test Procedure - High Power output, no attenuation
This test procedure is applicable to the:
It measures the power linearity of the module at the outputs indicated.
Example: Agilent 81600B #200 Power Linearity, Output 1.

Start = REF + 2.0 dBm 0.00 dBm + 0.00 dBm = 0.00 dBm
+ 1.0 dBm - 1.02 dBm + 1.00 dBm = - 0.02 dBm
0.0 dBm - 1.92 dBm + 2.00 dBm = + 0.08 dBm
-1.0 dBm - 2.95 dBm + 3.00 dBm = + 0.05 dBm
-2.0 dBm - 4.07 dBm + 4.00 dBm = - 0.07 dBm
-3.0 dBm - 4.96 dBm + 5.00 dBm = + 0.04 dBm
-4.0 dBm - 5.97 dBm + 6.00 dBm = + 0.03 dBm
-5.0 dBm - 6.98 dBm + 7.00 dBm = + 0.02 dBm
-6.0 dBm - 7.97 dBm + 8.00 dBm = + 0.03 dBm
-7.0 dBm - 8.98 dBm + 9.00 dBm = + 0.02 dBm
Maximum Power Linearity at current setting: + 0.08 dBm
Minimum Power Linearity at current setting: - 0.07 dBm
