Calibration Conditions - Keysight Technologies S9100A Startup Manual

7 Run Power Calibration

7. 1 Calibration Conditions

S9100A system performance is valid for an ambient temperature of 25°C unless
otherwise noted
S9100A system is within its recommended calibration cycle of one year
(described in the Data Sheet under "General Performance")
S9100A system has been stored at an ambient temperature within the allowed
operating range for at least two hours before being powered on
S9100A system has been powered on continuously for at least two hours
warm-up time, with IQ Analyzer or X-Series application (e.g. 5G NR) running
and the M1740A mmWave Transceiver powered on (verify that LEDs are on)
Depending on environmental conditions, longer warm-up time (up to 24 hours)
may lead to more stable results. If the system met these warm-up time require-
ments and there is a brief power shutdown, such as a system reboot, allow
45 minutes of warm-up time after the system is powered back on.
"Align Now All" alignments have been run in the M9410A PXIe VXT module, and
performed at least once within the previous seven days, after warm-up period;
see
A "Fast Alignment" has been run within the previous eight hours and
again if the temperature has changed more than 5°C from when the previous
"Fast Alignment" was performed
Amplitude accuracy characteristics apply after calibration has been performed
in the current environment and humidity has not changed by more than ±10%.

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
Before running Power Calibration on mmWave ports, confirm that
all of the following conditions are met; these same conditions are
also described in the
Using X-Apps to Perform Alignments on page 74
Returning for Service on page 18.
