Product recall : Increased cal factor uncertainty at high frequency and high
power levels
To Be Performed By: Agilent-Qualified Personnel (at 5320 only)
Parts Required:
P/N Description Qty.
None
Situation:
Agilent Technologies has determined that a portion of E9327A Peak and Average Power Sensors
shipped between November 2000 and June 2001 have been incorrectly calibrated at high power (greater
than 0dBm) and high frequency (greater than 6GHz).
Not all sensors produced within the above dates are affected. If the customer’s sensor does not appear
on the above list of serial numbers, it does not require re-calibration and is not affected by this recall.
This error has resulted in higher Calibration Factor Uncertainty values than recorded on the Calibration
Report provided with the power sensor. Our data indic at es your customer’s sensor exceeds the Cal
Factor Uncertainty specifications above 6GHz and at power levels above 0dBm. This is not a safety
concern. It is important to note that this only affects the uncertainty of the parameters, not the absolute
value.
Solution/Action:
Your customer has been asked to contact their regional Instrument Support Center to make
arrangements to return affected E9327A Power Sensor(s) for re-calibration at the factory as part of a
product recall described by Service Note E9327A-01. Contact information and instructions provided to the
customer are included below. Please note that an RMA number must be assigned and the sensor must
be returned to the factory at Rohnert Park, CA., through the Factory Repair Coordinator there.
Contact Information:
Within the USA:
Please call 1-800-403-0801
The Instrument Support Center will issue an “RMA” number and help to arrange for the shipment of
affected sensors back to the factory. The sensors will be shipped directly between the factory and
customer with the assistance of the ISC.
Outside of the USA:
Please contact the appropriate Agilent Equipment Service (Repair & Calibration) office for your country at
the following address:
http://www.tm.agilent.com/classes/MasterServlet?view=howtobuy&language=eng&locale=us
An “RMA” number will be issued and shipment to and from the factory will be handled by this
organization.
A re-calibration will be performed on your customer’s E9327A Power Sensor(s), free of charge. This
service will be performed promptly, and the sensor will be returned as quickly as possible. A re-calibration
of the power sensor at the factory is the only method of correcting the problem. There is no specific “work
around” other than determining whether the increased uncertainty above 6GHz and 0dBm is a problem.
Once re-calibrated, the sensor will meet all published specifications. If the power sensor has been
repaired and re-calibrated at the factory since manufacture, no additional calibration is necessary. The
recommended one-year calibration cycle should be restarted to the date of the re-calibration.
