Required Test Equipment

This section lists the test equipment needed to run performance tests and adjustments. Refer to each individual test for specific setup configurations with required cables and adapters. Not all of the listed test equipment needs to be connected to perform an individual test. To run a test, only the equipment specified for that test needs to be connected.

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.

Table Footnotes

  1. N5230A and N5230C Options: The software supports any option that covers the entire frequency range of the UUT.

  2. E5071C Options: This calibration application supports any option that covers the entire frequency range of the UUT.

  3. N1914A power meters with serial number prefix 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

  4. These power meters require a minimum firmware version to fix a power linearity accuracy issue:

    • N1912A requires minimum firmware version A.05.10 or above
    • N1914A requires minimum firmware version A.01.15 or above

  5. Option H50 required when testing U5532C power sensor modules. It is necessary to provide tighter uncertainties needed for the Internal Calibration Accuracy test and adjustment.

  6. For each power sensor model, three units are required to be used as the test equipment below:

    • Standard power sensor
    • Verification power sensor
    • Buried power sensor

  7. When ordering a new STD or CFT Power Sensor from Keysight to be used with the N7800A series applications, order with option 1A7. The 1A7 option provides an ISO17025 calibration and includes calibration data. When re-calibrating your STD or CFT Power Sensor for use with the N7800A series applications, we recommend the Keysight ISO17025 calibration.

  8. N8487A/8487A power sensor frequency range specified in the data sheet starts from 50 MHz. To calibrate power sensor modules with Option 550, the N8487A/8487A sensor needs to be calibrated from 30 MHz.

  9. Adapter intended for use only at 1 mW, 50 MHz power reference of the power meter.

  10. Can be used instead of a power sensor in the VSWR test.

Calibration Data Validation

Standard Checks

To ensure data integrity for measurements carried out with Test Management Environment (TME), the following verification checks are carried out at the beginning of each test run. The checks are only performed on devices that require calibration data which directly affect the test results. If you are unable to meet the calibration requirements for these devices contributing to the measurement uncertainty only, you may still produce valid reports using the standard report format option which does not contain any measurement uncertainty information.

You are still required to enter calibration factors other than the default, but uncertainty related data is not required to produce standard format reports.

 

The following table lists the standard checks performed by default:

Device Parameter name and description Limits A failure affects:
Power Sensor CalFactor (%)
The calibration factor, as a percentage
Must be ≥10% and ≤150% at all points.

Must not be 100% (the default) at all points.
All tests that require a power sensor

Uncertainty (%)[1]
The uncertainty of the calibration factor, as a percentage
Must be >0 and ≤10% at all points. Tests that require a power sensor are also guard-banded by measurement uncertainty
Reflection Coefficient Magnitude
The magnitude of the reflection coefficient
Must be >0 and <0.5 at all points. Tests that require a power sensor are also guard-banded by measurement uncertainty
Reflection Coefficient Phase (Degree)
The phase of the reflection coefficient, as a degree
Must be ≥–180° and ≤180° at all points.

Must not be 0° (the default) at all points.
All tests that require a power sensor, except for Linearity test
Reflection Coefficient Uncertainty
The uncertainty of the reflection coefficient magnitude
Must be non-zero at all points. Tests that require a power sensor are also guard-banded by measurement uncertainty
Reflection Coefficient Phase Uncertainty (+/– Degree)
The uncertainty of the reflection coefficient phase, as a degree
Must be >0° and ≤180° at all points. Tests that require a power sensor are also guard-banded by measurement
Power Splitter
(Port 2)[2]
Source Match
The magnitude of the equivalent source match
Must be >0 and ≤0.5 at all points.
All tests that require a power splitter
Source Match Phase (Degree)
The phase of the equivalent source match, as a degree
Must be ≥–180° and ≤180° at all points.

Must not be 0° (the default) at all points.
All tests that require a power splitter
Source Match Uncertainty
The uncertainty of the equivalent source match magnitude
Must be non-zero. Tests that require a power splitter are also guard-banded by measurement uncertainty
Source Match Phase Uncertainty (Degree)
The uncertainty of the equivalent source match phase, as a degree
Must be >0° and ≤180° at all points. Tests that require a power splitter are also guard-banded by measurement uncertainty

Table Footnotes

  1. TME expects the power sensor calibration factor uncertainty to be absolute uncertainty.

  2. The calibration data of Port 2 of the power splitter is required. Port 2 of the power splitter will connect to the Standard Power Sensor / Verification Power Sensor / UUT Power Sensor in the calibration factor test and its calibration data is required to calculate the calibration factor and the uncertainty. The calibration data of Port 3 of the power splitter is not required. Port 3 of the power splitter will connect to the Buried Power Sensor and its calibration data is not required to calculate the calibration factor and the uncertainty.

Failure to comply with the Calibration Factor (%), Reflection Coefficient, Reflection Coefficient Phase (Degree), Source Match or Source Match Phase (Degree) limits will result in the test data being labeled Invalid in both the TME interface and any report format produced from the data.

Failure to comply with the Cal Factor Uncertainty (%), Reflection Coefficient Uncertainty, Reflection Coefficient Phase Uncertainty (Degree), Source Match Uncertainty or Source Match Phase Uncertainty (Degree) limits will result in the data being labeled Invalid in the TME interface if Guard-banding is On, and in any report format, other than standard, produced from the data. If the Reflection Coefficient Phase Uncertainty (Degree) or Source Match Phase Uncertainty (Degree) is not available, please keep the default value ”r;0”. The application will calculate the worst case phase uncertainty and uses it to calculate the overall uncertainty.

1 mW Reference Output Power Calibration Data Validation

Prior to running the Internal Calibration Accuracy test, you are required to enter the 1 mW reference output power and the calibration uncertainty of the power meter used as the test equipment in the performance test and adjustment mentioned. This calibration information is required rather than the default information to be able to proceed with this test and adjustment.

The following standard checks are performed at the beginning of the Internal Calibration Accuracy test.

Device

Parameter Name and Description      

Limits

Power Meter Output Power (mW)

The 1 mW reference output power

Must be ≥0.99 mW and ≤1.01 mW


Uncertainty (+/-) (mW)

The uncertainty of the output power, in absolute value

Must be ≥0.0015 mW and ≤0.0035 mW

Required Calibration Data

When running a test that required the calibration data, the test will check if all the required calibration data exists.  If it is not, an error message will be prompted to ask you to enter the data.

Table 1 lists the UUT factory predefined frequency points at which the calibration data is required for the external test equipment (ETEs) for each UUT model.

Table 2 lists the equipment that needs to be calibrated at the specific frequency points listed in Table 1.

Please have your ETEs calibrated at those frequency points and enter the calibration data in TME before you run any test.

  1. When power sensor is selected as Network Analyzer 1-Port Cal Verification Device 1, the required frequency points are in Table 1. When verification kit is selected as Network Analyzer 1-Port Cal Verification Device 1, the software will use the calibration data come with the verification kit which may or may not match the frequency points in Table 1.

In the situation where you choose to run the VSWR and Calibration Factor test with additional frequency points, the test setup verification in those two tests will still only verify the factory predefined data points.

If the calibration data of the additional frequency points for the power splitter or the standard power sensor are not available, linear interpolated calibration data will be generated and used for those points when calculating calibration factor and the associated uncertainty.

The linear interpolation data is calculated by the following formula:  

where y is the calibration data and x is the frequency associated with the calibration data

 

Power Splitter Calibration Data in CITIFILE Format:

CITIfile is a standardized data format that is used for exchanging data between different computers and instruments. CITIfile stands for Common Instrumentation Transfer and Interchange file format. Below is an example of the CITIfile format calibration data files for the power splitter generated by the Keysight Standard Lab and the steps to generate TME required calibration data.

A power splitter of serial number 12345 has two files: 12345d and 12345u. One contains data and the other contains uncertainty.

12345d — This data file contains the S11, S21, S31, C22 (Port 2 equivalent source match), C33 (Port 3 equivalent source match), and tracking data.
These data are in real and imaginary format.

12345u — This uncertainty file contains the uncertainty of S11, S21, S31, C22, C33, and Tracking.
These data are magnitude uncertainty and phase uncertainty (degree).



 

Steps to Generate TME Required Calibration Data

The calibration data TME needs are Port 2 Source Match, Port 2 Source Match Phase (Degree), Port 2 Source Match Uncertainty, and Port 2 Source Match Phase Uncertainty (Degree)

  1. Port 2 Source Match and Port 2 Source Match Phase (Degree)

    1. Import the 12345d to an excel spreadsheet.

    2. Copy the frequencies to a column.

    3. Copy the 4th data block (C22 data block) after the frequency block to separate columns.

    4. Convert the (real, imaginary) data to (magnitude, phase[degree]) data. TME requires the phase to be a value between -180 and +180 degree. When converting the data, be sure to check the sign of the real and imaginary part to make sure the generated phase (degree) is in the correct quadrant.

      If you are using Microsoft Excel 2007, the following functions can be used to do the conversion.

  2. Port 2 Source Match Uncertainty and Port 2 Source Match Phase Uncertainty (Degree)

    1. Import the 12345u to an excel spreadsheet.

    2. Copy the 4th data block (C22 uncertainty data block) after the frequency block to separate columns. The 1st column is the uncertainty of the magnitude of the port 2 effective source match. The 2nd column is the uncertainty of the phase (degree) of the port 2 effective source match. No data conversion is needed for these two columns.

  3. Create a new spreadsheet to put the required data together.

    1. Copy the frequency column (from 1.b) to the 1st column.

    2. Copy the Port 2 source match magnitude (from 1.d) to the 2nd column.

    3. Copy the Port 2 source match magnitude uncertainty (from 2.b) to the 3rd column.

    4. Copy the Port 2 source match phase (degree) (from 1.d) to the 4th column.

    5. Copy the Port 2 source match phase uncertainty (degree) (from 2.b) to the 5th column.

    6. Save this spreadsheet as a CSV (comma delimited) file.

  4. Follow the instructions in TME Calibration Data XML File Generation Utility to generate a TME importable XML file with the csv file and import the XML file into TME.

 

TME Calibration Options:

Z2092B-208 Option

Z2092B-208 is a predefined TME calibration option for the Z2090B-207 Power Sensor test system. The Z2090B-207 Power Sensor test systems with option Z2092B-208 has a Network Analyzer lower frequency limit of 10 MHz. If this option is selected during the order creation of an N5532x Option 504 or U5532C Option 504 Unit Under Test (UUT), a limited calibration will be performed on the UUT.

VSWR will only be measured from 10 MHz to 4.2 GHz. The determination of Cal factor assumes the UUT meets it VSWR specifications for frequencies below 10 MHz. This results in higher Calibration Factor uncertainty for this limited calibration below 10 MHz.     

The calibration data of the splitters and the standard and verification power sensors are still required for the full frequency range 100 kHz to 4.2 MHz (see Table 1 for the required calibration data).
