N7821A Test Equipment

This section lists the test equipment needed to run performance tests and adjustments, any critical specification requirements, and recommended model numbers. The computer and all test equipment are connected to the device under test (DUT) using GPIB.

In all test equipment configurations, cables and adapters must be properly torqued. Exceeding recommended torque values can cause damage to a cable or adapter, and can cause inaccurate test results.

All test equipment requires a 30 minute warm-up period to ensure accurate performance.
Models for each Test Equipment category are given in order of preference. Alternate or substitute models are listed after the preferred model, but should be considered as a lower priority.
The "Normal" variant is no longer applicable for the Performance Verification Test Plan. The "Recommended" variant now supports both the 8902A/8903B for the measuring receiver tests previously supported in the Normal variant, and the PXA spectrum analyzer for all measuring-receiver tests. The PXA spectrum analyzer is the preferred solution. Refer to the table below for supported models and option requirements.

N9030A Analog Demodulation Application Option Requirements

To use the PXA N9030A with N9063EM0E analog demodulation measurement application functionality above 3.5 GHz, the N9030A must be upgraded with one of the following upgrade options: MTU or TES. After either upgrade, the N9030A must be re-calibrated for analog demodulation specifications above 3.5 GHz to be valid.

Choose from one of the following options:

Option MTU — Multi-Touch User Interface
- For analog demodulation specifications above 3.5 GHz to be valid, Option MTU can only be installed on N9030A instruments with serial number prefix greater than or equal to MY/SG/US5449.
Option TES — TOI Enhanced Specifications
- Option TES is a Keysight-only internal option. Keysight service centers need to contact the CSG support node to obtain an internal license key for this option.

Options for USB Ports on the N1914A Power Meter

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

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:

Order Option 1A7 when ordering new power sensors that will be used as working standards in N7800A TME calibrations.
When ordering periodic calibration for instruments used as lab standards in the N7800A software, we recommend using “Keysight Cal + Uncertainties + Guardbanding”. More information can be found at http://www.keysight.com/find/americas_cal.
The N7800A 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 N7800A measurement uncertainties then reflects these lower device uncertainties. The equipment requirements of each N7800A 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 TME 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
