Keysight Technologies N5262BW/BT/BR/DRxx Mini VNAX Frequency Extension Modules
Modules sold for use with 1.2 meter cable sets have a 10 dBm (± 3 dBm) RF and
LO power requirement at module inputs. For direct connection ONLY using FOM,
the PNA source power may indicate unleveled at 10 dBm. Reduce power until the
unleveled warning turns off, ensuring the power level is at least 7 dBm at input to
module.
IMPORTANT!
The RF and LO test set controller power level is a nominal +10 dBm, and is
configured to drive standard (+10 dBm input) VDI heads using 1.2m cables or
low power (+2 dBm input) VDI heads using 5m cables. If low power VDI heads
are connected to the test set controller using 1.2m cables, an 8 to 10 dB
attenuator must be placed on each RF and LO cable connected to the modules.
For low power VDI modules that are directly connected to the Keysight PNA/
PNA-X with a 1.2m cable set, the VNA port power driving the RF and LO must be
set to the nominal +2 dBm.
