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 measurements at low (–30 dBm) power levels.

The table below shows the various options that will provide USB ports on the N1914A power meter. Note that the N1914B power meter comes standard with USB ports.

The following options are ordered as upgrades to an existing N1914A power meter.
106	This is the recommended option.	Dual channel average power meter with 1 front and 1 rear USB port	008
103	alternate	Dual channel average power meter, battery, 2 rear USB ports	001, 009
105	alternate	Dual channel average power meter with VGA, battery, 1 front and 1 rear USB port	008, 010
108	alternate	Parallel rear-panel sensor input connectors, front-panel reference calibrator connector, 2 rear USB ports	002, 009
109	alternate	Parallel rear-panel sensor input connectors, rear-panel reference calibrator connector, 2 rear USB ports	003, 009
111	alternate	Dual channel average power meter, battery, 1 front and 1 rear USB port	001, 008
167	alternate	Dual channel average power meter, external trigger in/out, 1 front and 1 rear USB port	008, 012

^*The firmware will respond with the option numbers as determined by the installed orderable option. ETMS will look for either USB option 008 or 009.

The step attenuators should be permanently joined using the Interconnect Kit as shown in the diagram.

Guidelines for Ordering Power-Sensor Calibration Service

Use the following guidelines to ensure power sensors used by the N78000B application receive the correct calibration service:

Order Option 1A7 when ordering new power sensors that will be used as working standards in N78000B ETMS calibrations.
When ordering periodic calibration for instruments used as lab standards in the N78000B software, we recommend using “Keysight Cal + Uncertainties + Guardbanding”. More information can be found at http://www.keysight.com/find/americas_cal.
The N78000B software incorporates the ISO GUM Uncertainty in point-to-point uncertainty calculations. The special “H-series” calibration options (shown on the Special Calibrations Matrix located at http://cal.software.keysight.com) provide lower measurement uncertainties through use of direct comparison to devices directly characterized by NPL or NIST (or another NMI). The overall resulting N78000B measurement uncertainties then reflects these lower device uncertainties. The equipment requirements of each N78000B calibration application are summarized in the Special Calibrations Matrix which can be found at http://cal.software.keysight.com.

Option H99 is a special option for the Roseville Service Center [only] which provides electronic calibration data available as a .csv file that can be imported into ETMS thus avoiding manual entry. Option H99 must be requested from the Roseville Service Center upon re-calibration only of any previously purchased power sensor and not for new purchases of power sensors. This option may be ordered in addition to any other required or requested Std Lab Calibration option. Option H99 is recommended but not required.

The following models are not supported by Option H99:

E9304A-H18, H19, H84
E9300A-H25
N8386A
N8486AQ
