Source Port Setup
RF Output Control
The PXT has one receiver and two sources. Source1 can be routed to either RF1 Output or
RF1 Input /Output. Source 2 is always routed to RF2 Output. The settings RF1 Front Panel Output and
RF2 Front Panel Output in the RF Output Control menu determine this routing. RF2 Front Panel Output is
grayed out.
The sources’ baseband signals normally connect internally to the RF signal generators. However, the
baseband signals (balanced I and Q signals) may be routed to the rear panel to enable UE baseband-to-
baseband testing. The RF DL Output setting in the RF Output Control menu determines the baseband
routing.
Source power and modulation can be turned On/Off using the RF and MOD keys above the ports. LEDs
indicate the power and modulation state of each source.
