N78110B Required Test Equipment

This section lists the test equipment needed to run performance tests. Models for each test equipment category are given in order of preference. Alternate models are also listed but should be considered a lower priority. All equipment is Keysight, Agilent, or Hewlett Packard unless otherwise specified. Refer to each individual test for specific setup configurations.

UXA models with frequency option 526 will be tested on the 2.4 mm connector — not the 2.4 mm to 3.5 mm adapter. Remove the adapter if it's present on the DUT.

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.

USB power sensors require a power meter with USB ports. The table below shows the various options that will provide USB ports on the recommended N1914A power meter.

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
