4. 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.
5. 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).
