7 Run Power Calibration
S9100A 5G Multi-Band Vector Transceiver, Startup Guide 63
All needed alignments and calibrations were performed at the
factory before this S9100A system was shipped.
Power Calibration on mmWave ports should be performed
at least once a week to correct for drift caused by
temperature or humidity changes.
If additional calibrations are required, contact
Keysight Support; see
Returning for Service on page 18 .
All S9100A standard configurations have mmWave ports
RF Tx/Rx 1
➀ &
RF Tx/Rx 1
➁
M1740A mmWave Transceiver have ports
RF Tx/Rx 1
➀
&
RF Tx/Rx 1
➁
that can be calibrated when Port Selection is set to one of the following:
RRH 1 RFHD 1 -> RRH 1 RFHD 2
RRH 1 RFHD 2 -> RRH 1 RFHD 1
All S9100A standard configurations have RF ports that are either
RF Out
➂ and
RF In
➃ or
RF Out
➄ and
RF In
➅ .
S9100A Option RH1 and 007 have RF Transceiver ports
RF Out
➂
and
RF In
➃
and
S9100A Option 022 have RF Transceiver ports
RF Out
➄
and
RF In
➅
Although output and input ports
RF Out
➄
and
RF In
➅
with a Blocker have the
same name on the external labeling as ports
RF Out
➂
and
RF In
➃
without a
Blocker, they have different system performance.
Differences are because S9100A Option 022 have different source system
performance than an S9100A Option RH1. On an S9100A Option 022, the
Transmit (Tx)
RF Out
➄
, 380 MHz to 6 GHz, signal path is routed through a
hybrid combiner with additional cabling and switching that combines the RF Out
of a Primary Transceiver (M9410A PXIe VXT), “Wanted” signal, with the RF Out of
a Secondary Transceiver (M9410A PXIe VXT), “Blocker” signal. The
RF In
➅
path
is not affected by the Blocker on an S9100A Option 022.
RF Out
➂
and
RF In
➃
or
RF Out
➄
and
RF In
➅
can be calibrated when Port Selection is set to:
RF Output -> RF Input
Some S9100A standard configurations have High IF ports
RF Out
➆
and
RF In
➇
.
S9100A Option 007 and 022 have RF Transceiver High IF ports
RF Out
➆
and
RF In
➇
that route the signal path through up and down
converters, located in the Keysight E7770A Common Interface Unit (CIU),
along with additional cabling and switching which results in
signals ranging from 6 to 12 GHz.
RF Out
➆
and
RF In
➇
can be calibrated when Port Selection is set to:
IFIO 1 -> IFIO 1
