Overview
The apl_fem.vba shows front end module (FEM) measurement as a sample
program of measurement using the E5091A.
• If the E5071C does not have 4-port S parameter test set, a
runtime error occurs because there are parameters that cannot
be measured.
• This VBA program cannot control the E5091A-016, the multiport
test set.

EGSM:Antenna-Rx (channel 2), GSM1800:Tx-Antenna (channel 3), and
GSM1800:Antenna-Rx (channel 4) of the 6-port dual-band FEM as shown
in the below figure.
