Open between the Pins19 and 20. Measure the
output between the Pins22 and 23 when a sign-
al (–55dBm) is input to the Pin18.
Open between the Pins19 and 20. Measure the out-
put distortion factor between the Pins 22 and 23
when a signal
(–55dBm)
is input to the Pin18.
Input a signal to the Pin18 and measure
the output between the Pins22 and 23 at
an output distortion factor of 5%.
