Use the following guidelines to ensure power sensors used by the N7800A application receive the correct calibration service:
Order Option 1A7 when ordering new power sensors that will be used as working standards in N7800A TME calibrations.
In the Americas region, order the Keysight Cal + Measurement Uncertainty for power sensor recalibration.
Outside the Americas region, order ISO 17025/ILAC-G8 calibration service for power sensor recalibration.
When ordering periodic calibration for instruments used as lab standards in the N7800A software, we recommend using “Keysight calibration + uncertainties” for power sensors, and “Keysight calibration + uncertainties + guardbanding” for all other items (please visit Selecting the Right Calibration Services). The N7800A software incorporates the ISO GUM Uncertainty in point-to-point uncertainty calculations. The special “H-series” calibration options in this table provide lower measurement uncertainties through use of direct comparison to devices directly characterized by NPL or NIST (or another NMI). Please order Option H99 to get data on a CD for easy import into the N7800A (avoids manual entry). The overall resulting N7800A measurement uncertainties then reflects these lower device uncertainties. The equipment requirements of each N7800A calibration application are summarized in the specials calibration matrix which can be found at the Recommended Lab Standards and Special Cal Options website.
The Keysight Option H99 is a special option for the Roseville Service Center [only] which provides a CD with calibration data included as a .csv file in TME N7800A format for all power sensors used with the N7800A TME application. N7800A TME is SSU calibration software used across Keysight SSU and by many self-maintainers. H99 must be requested from the Roseville SSU upon re-calibration only of any previously purchased power sensor and not for new purchases of BID Power Sensors. This option provides for adding the calibration data to a CD and may be ordered in addition to any other required or requested Std Lab Calibration option (must also be ordered in addition to H99).
