Guidelines for Ordering Power-Sensor Calibration Service
Use the following guidelines to ensure power sensors used by the N7800A
application receive the correct calibration service:
1. Order Option 1A7 when ordering new power sensors that will be used as
working standards in N7800A TME calibrations.
2. In the Americas region, order the Keysight Cal + Measurement Uncertainty
for power sensor recalibration.
3. Outside the Americas region, order ISO 17025/ILAC-G8 calibration service
for power sensor recalibration.

a. N1914A power meters with serial number prior to MY53040007 require Service Note N1914A-07 which fixes a power
supply ground loop. The ground loop injects noise into the measurement circuits which can cause unstable measure-
ments at low (-30 dBm) power levels.
b. The frequency reference is optional. It may be a 10 MHz
"house
standard", or it may be the internal frequency refer-
ence time-base of the counter used for the frequency measurement. See the Frequency Reference Explanation section
in the Frequency Accuracy test for details.
