Safety and Regulatory Information General Safety Considerations

General Safety Considerations

Before Applying Power

If this product is not used as specified, the protection provided by the equipment could be impaired. This product must be used in a normal condition (in which all means for protection are intact) only.

The measuring terminals on this instrument are designed to be used with external signals described in Measurement Category I, but NOT with external signals described in Categories II, III, and IV. The input of this instrument cannot be connected to the mains.

The Mains wiring and connectors shall be compatible with the connector used in the premise electrical system. Failure to ensure adequate earth grounding by not using the correct components may cause product damage, and serious injury.

Servicing

These servicing instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing unless you are qualified to do so.

Operating Conditions

Operator is responsible for maintaining safe operating conditions. To ensure safe operating conditions, P937xAs should not be operated beyond the full temperature range documented in the P937xA Data Sheet (http://literature.cdn.keysight.com/litweb/pdf/5992-2765EN.pdf). Not maintaining safe operating conditions can result in shorter P937xA lifespans, improper P937xA performance, and user safety issues. If P937xAs are allowed to exceed the specified full temperature range, P937xA surface temperatures can cause discomfort or burns if touched. If a P937xA exceeds the full temperature range, always allow it to cool before touching it or removing it from the chassis.

This product is designed for use in Installation Category II and Pollution Degree 2 environment.

Safety and Regulatory Information Electrostatic Discharge Protection

Electrostatic Discharge Protection

Most causes of instrument failure can be avoided if you will apply the information in this section. PLEASE READ!

Electrostatic discharge (ESD) can damage or destroy electronic components. Use a static-safe work station to perform all work on electronic assemblies.

Figure 1-1 on page 1-12 shows a static-safe work station using two types of

ESD protection: conductive table-mat and wrist-strap combination, and conductive floor-mat and heel-strap combination. Both types, when used together, provide a significant level of ESD protection. Of the two, only the table-mat and wrist-strap combination provides adequate ESD protection when used alone. To ensure user safety, the static-safe accessories must provide at least 1 meg-ohm of isolation from ground.

Do NOT use these techniques for a static-safe work station when working on circuitry with a voltage potential greater than 500 volts.

Tests, Adjustments, and Troubleshooting About System Verification and Performance Tests

About System Verification and Performance Tests

The performance of the network analyzer is specified in two ways: system specifications and instrument specifications. It is the end user’s responsibility to determine which set of specifications is applicable to their use of the network analyzer.

A network analyzer measurement “system” includes the network analyzer, calibration kit, test cables, and any necessary adapters. The system verification software is used to verify the system’s conformance to the “system” specifications. A “pass” result demonstrates that the network analyzer test cables and adapters perform correctly as a system. It DOES NOT demonstrate that any one component performs according to its individual specifications. A change to any part of this measurement system requires a re-verification of the system.

Instrument specifications specify the network analyzer’s uncorrected measurement port characteristics and its output and input behavior. The performance tests are used to verify the module’s conformance to “instrument” specifications. Refer to “Test Management Environment (TME) Performance

Tests” on page 45.

System Specifications

System specifications specify warranted performance of the measurement system when making error-corrected measurements using the same calibration kit and test cables used during the system verifications routine. System specifications are applicable only when the measurement system is used to make error-corrected measurements.

The network analyzer’s system specifications are described in the Data Sheet, available online at

http://literature.cdn.keysight.com/litweb/5992-2765EN.pdf.

System specifications are expressed in two ways:

— residual errors of the measurement system shown as tabular specification

values

— graphs of measurement uncertainty versus reflection and transmission

coefficients

System specifications are verified in one of the following ways:

— Complete the system verification procedure using a certified verification kit

and certified calibration kit that will be used for future measurements.

— Complete all of the performance tests using a certified calibration kit that

will be used for future measurements. This alternative verifies both the system specifications and the instrument specifications for the network analyzer.
