Electrostatic Discharge Protection E8362B, E8363B, E8364B

Electrostatic Discharge Protection

Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables to the network analyzer. Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged. Static discharges too small to be felt can cause permanent damage. To prevent damage to the instrument:

• always have a grounded, conductive table mat in front of your test equipment.

• always wear a grounded wrist strap, connected to a grounded conductive table mat,

having a 1 MΩ resistor in series with it, when handling components and assemblies or when making connections.

• always wear a heel strap when working in an area with a conductive floor. If you are

uncertain about the conductivity of your floor, wear a heel strap.

• always ground yourself before you clean, inspect, or make a connection to a

static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly.

• always ground the center conductor of a test cable before making a connection to the

analyzer test port or other static-sensitive device. This can be done as follows:

1. Connect a short (from your calibration kit) to one end of the cable to short the center conductor to the outer conductor.

2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.

3. Connect the other end of the cable to the test port and remove the short from the cable.

Figure 1-1 shows a typical ESD protection setup using a grounded mat and wrist strap.

Option 010, Time Domain

An Option 010 analyzer can display the time domain response of a network or test device by calculating the inverse Fourier transform of the frequency domain response. This calculation allows the Option 010 analyzer to show the response of a test device as a function of time or distance. In time domain, the magnitude and location of a discontinuity and the characteristics of individual transmission paths of a network or test device can be determined. Time domain operation retains all the accuracy of active error correction.

Option 014, Configurable Test Set

An Option 014 analyzer can be configured to measure high-power devices and devices for high dynamic range.

For a high-power measurement, external amplifiers and high power attenuators or isolators can be added to complete the test setup. Test port output power up to 1 Watt (+30 dBm) can be applied to the device under test (DUT). Additionally, there is an external reference input that allows the external amplifier’s frequency response and drift to be ratioed out.

Tests and Adjustments PNA Series Microwave Network Analyzers

Before You Begin E8362B, E8363B, E8364B

Before You Begin

Before checking, verifying, or adjusting the analyzer, refer to the following paragraphs to:

• make sure the operating environment is within its requirements

• make sure that proper electrostatic discharge (ESD) protection is provided

• make sure the analyzer has warmed up properly to achieve system stability

• review the principles of connector care

Verify the Operating Environment

Due to their operating specifications, the verification and calibration kit devices determine your operating environment conditions. Open the calibration and verification kits and place all the devices on top of the foam inserts so they will reach room temperature. As the device dimensions change with temperature, their electrical characteristics change as well. It is necessary to keep the environmental levels within the limits stated in the PNA Series Installation and Quick Start Guide, Chapter 3, located online at:

http://cp.literature.agilent.com/litweb/pdf/E8356-90001.pdf

Protect Against Electrostatic Discharge (ESD)

This is important. If not properly protected against, electrostatic discharge can seriously damage your analyzer, resulting in costly repair.

CAUTION To reduce the chance of electrostatic discharge, follow all of the

recommendations outlined in “Electrostatic Discharge Protection” on

page 1-6, for all of the procedures in this chapter.

Allow the Analyzer to Warm Up

NOTE To achieve the maximum system stability, allow the analyzer to warm up for

at least 90 minutes.

Tests and Adjustments PNA Series Microwave Network Analyzers

About System Verification and Performance Tests E8362B, E8363B, E8364B

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 PNA.

A network analyzer measurement “system” includes the analyzer, calibration kit, test cables, and any necessary adapters. The system verification software in the PNA is used to verify the system’s conformance to the “system” specifications. A “pass” result demonstrates that the 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 PNA performance tests are

used to verify the analyzer’s conformance to “instrument” specifications.

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 verification routine. System specifications are applicable only when the measurement system is used to make error-corrected measurements.

The analyzer's system specifications are described in the Agilent PNA Series Network Analyzer Technical Specifications and also in the analyzer’s on-line help system in the section titled “Corrected System Performance”.

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, or

• 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 analyzer.

Instrument Specifications

The analyzer's instrument specifications are described in the Agilent PNA Series Network Analyzer Technical Specifications and also in the analyzer’s on-line help system in the

sections titled “Uncorrected System Performance”, “Test Port Output”, and “Test Port Input”.

These specifications apply when the analyzer is used to make either raw or error-corrected measurements.

3-6 Service Guide E8364-90026

PNA Series Microwave Network Analyzers Tests and Adjustments

E8362B, E8363B, E8364B About System Verification and Performance Tests

System Verification Procedure

The system verification procedure tests the network analyzer measurement “system”, as defined previously, against the system specifications. If confirmation is successful, the measurement system is capable of making measurements to the accuracy specified by the graphs of measurement uncertainty.

The procedure consists of calibrating the analyzer with a calibration kit, measuring a set of characterized devices, and comparing the resultant measured data to the data and uncertainty limits supplied with the verification kit. The device data provided with the verification kit has a traceable path to NIST. The total measurement uncertainty limits for the performance verification are the sum of the factory measurement uncertainties and the uncertainties associated with measuring the same devices on the system being verified. The difference between the factory-measured data and the verification-measured data must fall within the total uncertainty limits at all frequencies for the total system uncertainty test to pass.

NOTE Calibration kits are different from verification kits. Calibration kits are used

to determine the systematic errors of a network analyzer measurement system. Verification kits are used to confirm system specifications and are not

used to generate error correction.

Performance Tests

Performance tests are used to confirm analyzer performance against the “instrument” specifications. If confirmation is successful, the analyzer meets the instrument specifications.

Performance tests are contained in the N7840A Software Package and are described at

“Performance Tests (Agilent N7840A Software Package)” on page 3-31.

An illustrated outline of the performance verification procedure:

• for ANSI/NCSL Z540-1-1994 verification, is shown in Figure 3-1 on page 3-9.

• for non-ANSI/NCSL Z540-1-1994 verification, is shown in Figure 3-2 on page 3-10.

Certificate of Calibration

Agilent Technologies will issue a certificate of calibration upon successful completion of system verification or completion of the performance tests. The certificate of calibration will apply to the “system” (analyzer, calibration kit, test cables, and any necessary adapters) if the system verification procedure is used to confirm the system specifications. If the performance tests are used to confirm instrument specifications, the certificate of calibration will apply to the PNA as an independent instrument. The equipment and measurement standards used for the tests must be certified and must be traceable to recognized standards.

NOTE If you have a measurement application that does not use all of the

measurement capabilities of the analyzer, you may ask your local Agilent Technologies service office to verify only a subset of the specifications. However, this “limited calibration” creates the possibility of making

System Verification E8362B, E8363B, E8364B

System Verification

System verification is used to verify system-level, error-corrected uncertainty limits for network analyzer measurements. The verification procedure is automated and is contained in the firmware of the analyzer.

The device data provided with the verification kit has a traceable path to a national standard. The difference between the supplied traceable data and the measured data must fall within the total uncertainty limits at all frequencies for the system verification to pass.

The total measurement uncertainty limits for the system verification are the sum of the factory measurement uncertainties for the verification devices and the uncertainties associated with the system being verified. You can determine your system measurement uncertainty limits by referring to the analyzer embedded on-line help.

IMPORTANT Passing this system verification does not guarantee that the analyzer meets

all of its performance specifications. However, it does show that the network analyzer being verified measures the same devices with the same results as a factory system which has had all of its specifications verified and its total measurement uncertainty minimized.

What the System Verification Verifies

The system verification procedure verifies proper operation of the:

• network analyzer

•calibration kit

• test port cables

together as a “system”. It DOES NOT verify that any of these components pass their specifications independently. The user is responsible for independently calibrating and verifying the proper operation of the calibration kit and test port cables prior to performing the system verification.

NOTE Additional equipment or accessories used with the above system are not

verified by system verification.

Measurement Uncertainty

Measurement uncertainty is defined as the sum of:

• the residual systematic (repeatable) errors, and

• the random (non-repeatable) errors

in the measurement system after calibration.

The systematic errors are:

• directivity,

• source match,

•load match,

• reflection and transmission frequency tracking, and

• isolation (crosstalk).

The random errors include:

•noise,

•drift,

• connector repeatability, and

• test cable stability.

A complete description of system errors and how they affect measurements is provided in the analyzer’s on-line embedded help.

Any measurement result is the vector sum of the actual test device response plus all error terms. The precise effect of each error term depends on its magnitude and phase relationship to the actual test device response. When the phase of an error response is not known, phase is assumed to be worst-case (−180° to +180°). Random errors such as noise and connector repeatability are generally combined in a root-sum-of-the-squares (RSS) manner.

Measurement Traceability

To establish a measurement traceability path to a national standard for a network analyzer system, the overall system performance is verified through the measurement of devices that have a traceable path. This is accomplished by measuring the devices in an Agilent verification kit.

The measurement of the devices in the verification kit has a traceable path because the factory system that measured the devices is calibrated and verified by measuring standards that have a traceable path to the National Institute of Standards and Technology (NIST) (see Figure 3-8). This chain of measurements defines how the verification process brings traceability to the network analyzer system.

Performing System Verification

The following verification procedure is automated by the analyzer firmware. For each verification device, the analyzer reads a file from the verification disk and sequentially measures the magnitude and phase for all four S-parameters.

IMPORTANT For system verification to perform correctly, it is NECESSARY that the

verification devices be measured with their female connectors connected to Port 1 and their male connectors connected to Port 2.

NOTE The following procedure, and the connection prompts given, assumes only one

female-to-female cable connected to Port 2. However, this procedure can also be performed with the addition of a female-to-male cable connected to Port 1.

NOTE Although the performance for all four S-parameters are measured, the S11

Cable Substitution

The test port cables specified for the network analyzer system have been characterized for connector repeatability, magnitude and phase stability with flexing, return loss, insertion loss, and aging rate. Since test port cable performance is a significant contributor to the system performance, cables of lower performance will increase the uncertainty of your measurement. Refer to the plots in the cable tests (earlier in this chapter) that show the performance of good cables. It is highly recommended that the test port cables to be regularly tested.

If the system verification is performed with a non-Agilent cable, ensure that the cable meets or exceeds the specifications for the RF cable specified in the above table,

“Equipment Supported by the System Verification Procedure.” Refer to the cable’s user’s

guide for specifications.

Dynamic Accuracy Test

Function of the Test: To measure the relative power linearity of the analyzer’s receivers.

Specification Tested: Test Port Input–Dynamic Accuracy

Equipment Used: The dynamic accuracy test set (Z5623A Option H01), a power meter

(E4418B or E4419B) power sensors, and two test cables.

Description of the Test:

1. The analyzer’s test ports are tested separately at a specific CW frequency and a

reference power level of −20 dBm.

2. The analyzer’s driving port is connected to the dynamic accuracy test set’s source port and the analyzer’s receiving port is connected to the dynamic accuracy test set’s receiver port. A power sensor is connected to the dynamic accuracy test set’s power meter port.

3. The dynamic accuracy test set is used to input a signal from the driving port on the analyzer. The input signal is routed through step attenuators to both the analyzer and a power sensor.

4. The analyzer source and the dynamic accuracy test set create power levels that are “deltas” from the reference power level of −20 dBm. Each delta is measured two ways: by the power sensor and by the analyzer’s receiver under test.

5. The analyzer’s power level into the port under test is set to the −20 dBm reference level.

6. The power level is measured with the power sensor: (P

7. The power level is measured using the analyzer’s receiver under test: (P

8. The power level into the analyzer’s port under test is stepped, in 5 dB steps, over the range of 0 to −120 dBm. Each power level represents a “delta” from the reference level.

9. At each step, the power level is measured using the power meter: (P

10. At each step, the power level is measured using the receiver under test: (P

Receiver Calibration Adjustment

The receiver calibration is used to adjust the network analyzer receivers for a flat response across its full frequency range:

1. A power meter/sensor is connected to Port 1, as shown in Figure 3-22, to establish a reference for flatness.

2. A cable is inserted between the power sensor and the test port, as shown in Figure 3-23, to establish a reference for the cable.

3. The same cable is connected between the two test ports, as shown in Figure 3-24, and a signal from Port 1 is used to adjust the “B” receiver at Port 2.

The adjustment is repeated using a signal from Port 2 to adjust the “A” receiver at Port 1.

Data obtained during this adjustment are stored in the mxcalfile_pxx files on the hard disk drive (where xx is a 1 or 2 digit number). The data are used in subsequent measurements.

If the hard disk drive is replaced, these mxcalfile_pxx files will be lost. Therefore, they should be backed up (saved on a floppy disk) so that they can be restored. If using multiple disk drives (e.g. classified and general usage), then these files must be replaced on each individual disk drive.

These files can be recreated by performing another receiver calibration adjustment.

Power Up Troubleshooting

WARNING Immediately unplug the instrument from the ac power line if the

unit shows any of the following symptoms:

• Smoke, arcing, or unusual noise from inside the analyzer.

• A circuit breaker or fuse on the main ac power line opens.

Check your network analyzer for evidence that it is powering up correctly. Perform the following steps and make sure that the analyzer is displaying correct behavior as noted in the following steps.

Step 1. Disconnect all peripherals and plug in the network analyzer. Before the analyzer

is powered on, the line switch should glow yellow and no other lights should be on.

Step 2. Turn on the network analyzer.

• The line switch should glow green.

• The fans should be audible.

• The display should flash and then show the hardware boot-up sequence. This process checks the RAM and communication with the hard disk drive. These checks return an error message if a problem is detected.

• The Windows 2000 operating system should start.

• The network analyzer measurement interface should open with an S

measurement displayed.

Step 3. If the analyzer powers up correctly, continue troubleshooting with “Front Panel

Troubleshooting” on page 4-17.

Step 4. If the analyzer does not power up correctly, follow these troubleshooting steps:

• If the line switch does not glow or the fans are not operating (audible), go to

“Power Supply Check” on page 4-7.

• If you cannot hear the fans operating, go to “If the Fans Are Not Operating” on

page 4-12.

• If the line switch glows green and the fans are operating (audible), but the display remains dark, go to “Troubleshooting LCD Display Problems” on

page 4-13.

• If the instrument appears to abort the network analyzer measurement interface process, contact Agilent. Refer to “Contacting Agilent” on page 2-13.

PNA Series Microwave Network Analyzers Troubleshooting

E8362B, E8363B, E8364B Power Up Troubleshooting

Power Supply Check

NOTE There are no fuses to replace within the power supply. If you determine that

the power supply is the failed assembly, replace the power supply.

A catastrophic failure in the power supply can be determined by observing the line switch, and by measuring the probe power at the front-panel Probe Power connectors:

1. Ensure that the instrument is plugged in with the power switch in the standby position (power not switched on). Verify that the line switch glows yellow. A line switch that glows yellow indicates that the +15 VDC line (P15 STB) is providing enough voltage to light the LED. (The actual voltage may not be +15 VDC.)

2. Turn on the instrument power and verify that the line switch glows. When the line switch glows, it is an indication that the power supply has received an “ON” command and that the +5.2 VDC supply can supply enough current to light, at least, these lamps.

3. The front-panel probe power-connector can be used to check the +15 VDC and

−12.5 VDC (−15 VDC) supplies. The −12.5 VDC is produced by post regulating the

−15 VDC supply. Refer to Figure 4-2 for a diagram of the probe power connector.

If all of these supply voltages are missing, it is likely that the problem is either a defective A4 power supply, or another assembly is loading down the A4 power supply. Continue with

“If All Supply Voltages Are Missing” on page 4-10, to determine the cause of the problem.

If the line switch is lit correctly, and the probe power voltages measure within the specifications listed in Table 4-1 on page 4-9, the power supply has not suffered a catastrophic failure; however, the power supply could still be at fault. Continue with the next section to measure the individual voltage supplies.

Measure the Individual Voltage Supplies

WARNING The instrument contains potentially hazardous voltages. Refer to the

safety symbols provided on the instrument and in “General Safety

Considerations” on page 1-3 before operating the unit with the cover

removed. Make sure that the safety instructions are strictly followed. Failure to do so can result in personal injury or loss of life.

To measure the power supply voltages, it is necessary to remove the instrument’s outer and inner covers. Refer to “Removing the Covers” on page 7-6 for removal procedures. Use the E8356-60021 extender board to measure the individual power supply voltages. Insert the extender board into an empty slot next to the A6 signal processing ADC module (SPAM) board.

NOTE If any one individual voltage supply from the A4 power supply develops an

over-voltage or over-current problem, all supplies are affected. The supply goes into a “burp” mode characterized by the supplies cycling on and off at a low voltage level. The cause of the over-voltage or over-current condition can be the A4 power supply itself, or any assembly to which the A4 power supply provides voltage. To isolate the cause of “burp” mode, continue to the assembly removal process as described in the section titled “If All Supply

Voltages Are Missing” on page 4-10.

On the extender board, measure the power supply voltages using a digital voltmeter. Refer to Figure 4-3 for the power supply test points on the extender board. Use the point marked as “GND” for the ground connection. Refer to Table 4-1 on page 4-9 for the correct voltages.

If All Supply Voltages Are Missing

WARNING Disconnect the line-power cord before removing any assembly.

Procedures described in this document may be performed with power supplied to the product while protective covers are removed. Energy available at many points may, if contacted, result in personal injury or loss of life.

It is necessary to sequentially remove all of the assemblies, taking care to disconnect the line-power cord before each removal, and then to measure the supply voltages after each removal.

If the missing supply voltages return to a “power on” condition after removal of an assembly, suspect that assembly as being defective.

Remove the network analyzer assemblies in the order specified in the following steps (refer to Chapter 7 for removal instructions).

1. Unplug the test set motherboard cable from the A16 test set motherboard.

2. Unplug the front panel interface cable from the A3 front panel interface board.

3. Remove the A6 SPAM board.

4. Remove the A8 fractional-N synthesizer board.

5. Remove the A10 frequency reference board.

6. Remove the A11 phase lock board.

7. Unplug the A30 floppy disk drive from the A14 system motherboard.

8. Unplug the A31 hard disk drive from the A15 CPU board.

The minimum required assemblies to power up the analyzer are:

• A4 power supply

• A14 system motherboard

• A15 CPU board

To further isolate the failure in the three remaining assemblies, measure the resistance on the extender board (with the power turned off) from the power supply test points to “GND”. Refer to Figure 4-3 on page 4-9. The voltages should be as shown in Table 4-2.

NOTE Make sure that the only assemblies plugged in are the three minimum

required assemblies listed above.

Check for shorts (zero Ω) or very low resistance (approximately 1 Ω). If a short or low resistance is measured, isolate each of the remaining three boards in the following order, and recheck the shorted test point after each board is removed. Note that the resistance may be different from that listed in the table, but you should be able to determine if the shorted condition has changed.

Isolate the remaining three assemblies:

• remove the A15 CPU board

• remove the A4 power supply

• This leaves only the A14 system motherboard installed. If the measurements are still incorrect, this is the suspected faulty assembly.

If the Fans Are Not Operating

CAUTION The power supply may be in thermal shutdown if the instrument has been

operating without the fans running. Allow the instrument to cool down before troubleshooting.

If all three fans are not operating, suspect a power supply problem or a defective A14 system motherboard. Refer to “Power Supply Check” on page 4-7 to check the individual supplies. If the supplies are within specifications, the most probable cause is a defective A14 system motherboard. Refer to “Removing and Replacing the A14 System

Motherboard” on page 7-26.

If only one or two fans are not functioning, and the power supplies are within specifications, suspect the A14 system motherboard or a defective fan. Perform the following procedure.

1. Remove the front panel assembly from the instrument. Refer to “Removing and

Replacing the Front Panel Assembly” on page 7-10.

2. Refer to Figure 4-4. Measure the fan voltages at J1, J3, and J4 on the A14 system motherboard.

Figure 4-4 Fan Voltages

3. If the correct voltage is present and the fan connector is in good mechanical condition, suspect a defective fan. Refer to “Removing and Replacing the Midweb and the B1

Fan” on page 7-77.

4. If the voltage is not present, suspect a defective A14 system motherboard. Refer to

“Removing and Replacing the A14 System Motherboard” on page 7-26.

Troubleshooting LCD Display Problems

This procedure is intended to isolate the faulty assembly when the display is dark. If the display is lit, but the color mix is faulty, refer to “A2 Display Test” on page 4-19.

NOTE There are no front panel adjustments for intensity and contrast of the LCD.

1. If the display is dim, the backlight assembly is defective. Refer to “Removing and

Replacing the Front Panel Assembly” on page 7-10.

2. If the display is dark (not visible), connect an external VGA monitor to the rear panel VGA output connector on the instrument. Be aware that some multisync monitors might not be able to lock to a 60 Hz sync pulse. If the video information is not present on the external VGA monitor, the most probable cause is the A15 CPU board. Refer to

“Removing and Replacing the A15 CPU Board” on page 7-28.

3. If the external VGA monitor is functioning, verify that the front panel interface ribbon cable is properly plugged into the motherboard connector.

4. If the front panel interface ribbon cable is properly connected, suspect that one or more of the following is defective:

• inverter board (mounted on the display assembly)

• display lamp assembly

• A3 front panel interface board

• A2 display assembly

Refer to the following paragraphs to determine which of the above listed assemblies is defective.

Creating the Test Setup

For easy access to measure the voltages on the inverter board and on the A3 front panel interface board, it is best to disassemble the front panel and remove these two boards to set in front of you for testing. Use the ribbon cables that come with the boards and the analyzer as the supply source. Follow this procedure:

1. Turn off the analyzer.

2. Remove the front panel. Refer to “Removing and Replacing the Front Panel Assembly”

on page 7-10.

3. After the front panel is removed from the analyzer, isolate the inverter board by first removing the display assembly. Refer to “Removing the A2 Display Assembly” on

page 7-12. Put the A2 display assembly and its ribbon cables aside.

4. Remove the A3 board by referring to “Removing the A3 Front Panel Interface Board” on

page 7-12. Put the A3 board aside.

5. Duplicate the board connections on your ESD safe test desk top by laying the A2 and A3 in front of the open-faced analyzer. Lay the A2 and A3 boards component-side down, the A2 to the left of the A3, with the top of the boards towards you.

7. Turn the analyzer on and refer to “Verifying the Inverter Board” on page 4-14 and

“Verifying the A3 Front Panel Interface Board” on page 4-16 to test and troubleshoot

the boards.

Verifying the Inverter Board

WARNING High voltage is present on the inverter board and the A3 front panel

interface board. Be careful when measuring signals and voltages on these boards.

1. To access the front panel boards for measurements, it is necessary to remove the front panel assembly. Refer to “Removing and Replacing the Front Panel Assembly” on

page 7-10.

Using Figure 4-5 as a reference, measure the signals and voltages indicated in Table 4-3 on

page 4-14. If the signals and voltages measure good, the inverter board is functioning

correctly.
