Appendix 1
Connection between X6100 and XPA125B (L4001 cable)
After the X6100 connects with XPA125B power amplifier and antenna tuner AIO through the L4001 cables,
the output power can be expanded to 100W.
After connection, the X6100 can automatically control the wave band switching of XPA125B. Moreover, the
ALC control will be built between two machines. When the X6100 output power exceeds the power limit of
the XPA125B, the AACL control will automatically decrease the output power of the radio so that the output
power of the XPA125B will be kept to be about 100W.
We suggest to set the output power of the X6100 to be ≤2.5W to protect the amplifier equipment.
■ XPA125B power amplifier and L4001 cable need to be separately ordered.
