Flow Diagram of Procedure

The operational flow of the software is depicted by the flowchart shown

below.

Basic Calibration

Before executing calibration, you need to select a calibration kit. If you use a

calibration kit other than a predefined one, you need to define it. If the connector type

of the standard of the calibration kit you use has polarity (the distinction between

male and female), you need to change the standard class definition of the calibration

kit depending on the standard you actually use. For more information, see Modifying

Calibration Kit Definition.

If you select a predefined calibration kit, (m) and (f) in the name (label) of the

standard displayed in the soft key indicate male (m) and female (f) for the analyzer's

connector, respectively.

Click Select Port.

For 1-port;

In 1-port calibration, calibration data are measured by connecting an OPEN

standard, a SHORT standard, and a LOAD standard to the desired test port. This

calibration effectively eliminates the frequency response reflection tracking error,

directivity error, and source match error from thetest setup in a reflection test

using that port.

1. Press Cal Key.

2. Click Cal Kit, then select the calibration kit.

3. If the name (label) of the calibration kit has been changed, the label is displayed as

the soft key.

4. An asterisk (*) on the upper right of the softkey corresponding to a predefined

calibration kit indicates that its definition value has been changed from the factory

setting by the user.

5. Click Calibrate.

6. Select a test port (and corresponding S parameter) on which 1-port calibration will

be performed.

7. Connect an OPEN calibration standard to the selected test port (connector to which

the DUT is to be connected).

8. Click Open to start the calibration measurement.

9. Connect a SHORT calibration standard to the selected test port (connector to which

the DUT is to be connected).

10. Click Short to start the calibration measurement.

11. Connect a LOAD calibration standard to the selected test port (connector to which

the DUT is to be connected).

12. Click Load to start the calibration measurement.

13. Click Done to terminate the 1-port calibration process. Upon pressing this key,

calibration coefficients will be calculated and saved. The error correction function

will also be automatically enabled.

For 2-port;

In full 2-port calibration, calibration data are measured by connecting an OPEN

standard, a SHORT standard, or a LOAD standard to two desired test ports (or

a THRU standard between two ports).This calibration effectively eliminates the

directivity error, crosstalk, source match error, frequency response reflection

tracking error, and frequency response transmission tracking error from the test

setup in a transmission or reflection test using those ports. This calibration

makes it possible to perform measurements with the highest possible accuracy.

A total of twelve error terms, six each in the forward direction and the reverse

direction, are used in a calibration.

1. Press Cal key.

2. Click Cal Kit, then select the calibration kit.

3. If the name (label) of the calibration kit has been changed, the label is displayed as

the soft key.

4. An asterisk (*) on the upper right of the softkey corresponding to a predefined

calibration kit indicates that its definition value has been changed from the factory

setting by the user.

5. Click Calibrate > 2-Port Cal.

6. Click Select Ports, then select the test ports on which you will perform full 2-port

calibration. (In the procedure below, the selected test ports are denoted as x and y.)

7. Click Reflection.

8. Connect an OPEN calibration standard to test port x (the connector to which the

DUT is to be connected).

9. Click Port x Open to start the calibration measurement (x denotes the test port to

which the standard is connected).

If you select the calibration kit which has different calibration definitions for

each gender, (m) and (f) in the name (label) of the standard displayed in

the softkey indicate male (m) and female (f) for the analyzer's connector,

respectively.

10. Disconnect the OPEN calibration standard and replace it with a SHORT calibration

standard.

11. Click Port x Short to start the calibration measurement (x denotes the test port to

which the standard is connected).

12. Disconnect the SHORT calibration standard and replace it with a LOAD standard.

13. Click Port x Load to start the calibration measurement (x denotes the test port to

which the standard is connected).

14. Repeat the above procedure for port y.

15. Click Return.

16. Click Transmission.

17. Make a THRU connection between ports x and y (between the connectors to

which the DUT is to be connected).

18. Click Port x-y Thru to start the calibration measurement (x and y denote the test

ports between which the THRU connection is being made).

19. Click Return.

20. If an isolation calibration must be performed using a LOAD standard, follow the

procedure below.

21. Click Isolation (Optional).

22. Connect a LOAD standard to each of the two test ports (connectors to which the DUT

is to be connected).

23. Click Port x-y Isol to start the calibration measurement (x and y denote the port

numbers to which the LOAD standard is connected).

24. Click Return.

25. Click Done to terminate the full 2-port calibration process. Upon pressing this key,

calibration coefficients will be calculated and saved. The error correction function

will also be automatically enabled.

Safety

Safety Summary

The following general safety precautions must be observed during all phases of

operation, service, and repair of this instrument. Failure to comply with these precautions

or with specific WARNINGS elsewhere in this manual may impair the protection provided

by the equipment. Such noncompliance would also violate safety standards of design,

manufacture, and intended use of the instrument. Agilent Technologies assumes no

liability for the customer's failure to comply with these precautions.

Notes;

The E5071C complies with INSTALLATION CATEGORY II as well as POLLUTION

DEGREE 2 in IEC61010-1. The E5071C is an INDOOR USE product.

LEDPRODUCT

Ground the Instrument - To avoid electric shock, the instrument chassis and cabinet

must be grounded with the supplied power cable's grounding prong.

DO NOT Operate in an Explosive Atmosphere - Do not operate the instrument in the

presence of inflammable gasses or fumes. Operation of any electrical instrument in such an

environment clearly constitutes a safety hazard.

Keep Away from Live Circuits - Operators must not remove instrument covers.

Component replacement and internal adjustments must be made by qualified maintenance

personnel. Do not replace components with the power cable connected. Under certain

conditions, dangerous voltage levels may remain even after the power cable has been

disconnected. To avoid injuries, always disconnect the power and discharge circuits before

touching them.

DO NOT Service or Adjust the Instrument Alone - Do not attempt internal service or

adjustment unless another person, capable of rendering first aid and resuscitation, is

present.

Dangerous Procedure Warnings - Warnings, such as the example below, precede

potentially dangerous procedures throughout this manual. Instructions contained in the

warnings must be followed.

Dangerous voltage levels, capable of causing death, are present in this instrument.

Use extreme caution when handling, testing, and adjusting this instrument.
