Making Measurements

Calibrate the N9330B before making measurements

Before making a measurement (SWR/Return loss/Cable loss/DTF) in a specified frequency range or the full span, you must calibrate your N9330B.

It is important to keep the calibration frequency range as close as possible to the actual sweep frequencies necessary for the measurements. Calibrating over a larger frequency range than the actual measurement range will reduce the accuracy of the test results. For example, using a 1 GHz calibration range when the measurement range is only few kHz.

Performing one calibration is acceptable provided the calibration frequency range selected incorporates all intended measurement frequencies. If the frequency span is changed, a new calibration must be performed for that measurement. A new calibration must be performed if any components used in the calibration setup are changed. For example, a short coaxial cable used to connect the tester to the DUT.

Calibration Mode

The N9330B offers two calibration modes:

• FullSpan Cal Runs an open-short-load calibration across the full frequency span (25 MHz to 4 GHz).  A FullSpan Cal ignores the frequency changes during measurements.

• SelectedSpan Cal Performs an open-short-load calibration across a user-defined frequency span. A SelectedSpan Cal requires a re-calibration of the tester, after changing the measurement frequency range. Normally, the selected span should be set as close to the actual swept frequency range.

Types of Calibrators

Two types of calibrator tools are available from Keysight for use with the tester:

• T-combo calibrator This is a T-shaped mechanical calibrator. It consists of a calibrated open, short and 50  load. Using the T-combo calibrator will result in a more accurate calibration than when using the an Electronic calibrator.

• Electronic calibrator The Electronic calibrator enables you to perform a one-step calibration process. It automatically performs an open, short, and 50W load calibration. The Electronic calibrator is a faster but less accurate than when using a T-combo mechanical calibrator.

Making Measurements

Calibrating procedure introduction

Choose either the T-combo or the Electronic calibrator to perform a calibration process. Different combinations of calibration mode and calibrator may benefit the measurement accuracy differently. (Assuming the measurement resolution remains unchanged):

•Using SelectedSpan calibration mode and the T-combo calibrator provides a more accurate calibration.

• Selecting FullSpan calibration mode and electronic calibrator is the simplest, most convenient calibration.

The tester default setting is the SelectedSpan calibration mode. Keysight recommends using the SelectedSpan calibration mode for best results.

It is important to keep the calibration frequency range as close as possible to the actual sweep frequencies necessary for the measurements. Calibrating over a larger frequency span than the actual measurement range will reduce the accuracy. For example, using a 1 GHz calibration range when the measurement range is only few kHz.

Calibrate with an electronic calibrator

The tester needs about 35 sec. to record the data of an Electronic calibrator the first time a new Electronic calibrator is used with a specific tester.

After the initial use of an Electronic calibrator, the tester requires approximately 12 sec. to perform the automated open-short-load calibration.

The Electronic calibrator performs an automatic, open-short-load consecutively:

1Press [CAL] to bring up a dialog box for calibration

guidance.

2 Connect the Electronic calibrator to the RF OUT

connector on the top panel of the tester. Connect the USB cable between the electronic calibrator and the tester USB port. The correct USB cable is supplied with an Electronic calibrator.

3Press [ENTER] to start calibration.

Never connect an electronic calibrator to the tester until after powering on the N9330B.

Calibrate with a T-combo calibrator

Using a T-combo calibrator is a three step process requiring the user to manually change the open-short-load components. The default order of the calibration process is open-short-load.

1Press [CAL] to bring up the dialog box for calibration

guidance.

2 Connect the “Open” component of the T-combo

calibrator to the RF OUT connector of the tester. Press [ENTER] to start the open calibration.

3 Connect the “Short” component of the T-combo

calibrator to the RF OUT connector of the tester. Press [ENTER] to start the short calibration.

4 Connect the “Load” component of the T-combo

calibrator to the RF OUT connector of the tester. Press [ENTER] to start the load calibration.

A “Calibrated” indicator will be displayed on the upper left corner of the screen when the calibration is completed.

Using User Cal Mode A User Cal Mode is an optional selection when using a mechanical calibrator. The User Cal Mode allows the user to choose one cal standard from the open-short-load to perform a customized calibration.

For example, pressing  [CAL] > {User Cal Mode} > {Open} initiates a calibration using the Open calibration standard only.

Measuring Return Loss/SWR/Cable Loss

NOTE

Making Measurements

Measuring Return Loss/SWR/Cable Loss

Return loss is the measurement of the signal reflection characteristics of a cable and antenna system. A return loss measurement is useful in detecting problems in the antenna feedline system and the antenna itself. A portion of the incident power is reflected back to the source from transmission line faults as well as from the antenna itself. The ratio of the reflected voltage to the incident voltage is called the reflection coefficient. The reflection coefficient is a complex number, meaning it has both magnitude and phase information. In S-parameter terms, return loss is referred to as an S11 measurement.

SWR and cable loss measurement derive from return loss measurement.

Test signals can cause interference. When testing cables attached to an antenna, the test signal is radiated from the antenna. Verify that the signal used for the test CANNOT cause interference to other antennas.

Perform a basic return loss measurement

When measuring return loss, SWR, or cable loss with your N9330B, follow the same operation procedure as shown below.

To make a return loss (versus. frequency) measurement over a frequency range of 50 to 400 MHz, perform the following steps:

1Press the [MODE] hardkey to call up a measurement

mode menu. Rotate the front-panel knob to select a measurement mode (for this example, Return Loss). Press the [ENTER] hardkey to confirm your selection. For more detailed information, refer to "Selecting a

Measurement Mode" on page 24.

2Press the {Start} softkey to call up the start frequency

menu. Press {50} > [ENTER] to set the start frequency to 50 MHz.

Page 36

3Press the {Stop} softkey to call up the stop frequency

menu. Press {400} > [ENTER] to set the stop frequency to 400 MHz.

4Press the [CAL] hardkey to call up the calibration

process menu. Follow the instructions for performing the calibration. For more information about calibration, refer to "Calibrate the N9330B before

making measurements" on page 25.

A “Calibrated” indicator will be displayed on the upper left corner of the screen when the calibration is completed.

5 Remove the calibrator and connect the DUT to the RF

OUT connector of the tester. The tester will then measure the return loss of the DUT.

Adjusting the measurement resolution

The tester has three resolution settings, 521, 261, or 131 points. Press the [MEAS/VIEW] hardkey, then the {Resolution} softkey to choose the resolution setting desired, then press the [ENTER] hardkey to enter the selection.

The higher the resolution, the more accurate the measurement results. However, a higher resolution setting will require a longer sweep time.

Making Measurements

Measuring Distance to Fault (DTF)

For this measurement, an internally generated signal emits from the RF OUT port of the tester and is transmitted to the cable and antenna system (DUT). The tester receives and processes the signal power reflected from faults and imperfections.

In performing a DTF measurement, the tester uses frequency domain reflectometry. The transmitted and reflected signals contain information about the distance to the faults. This information is used to determine the physical distance to the faults. The tester displays the physical distance to the probable faults, corrected for cable loss and the velocity propagation factor of the cable.

Perform a DTF measurement

To make a DTF-return loss measurement over a frequency range of 50 to 400 MHz, perform the following steps:

1Press [FREQ/DIST] > {Start} > 50 > [ENTER] to set the

start frequency to 50 MHz.

2Press {Stop} > 400 > [ENTER] to set the stop frequency

to 400 MHz.

3Press the [MODE] hardkey to select a measurement

mode. Rotate the front-panel knob to highlight and select the DTF-Return loss, and press [ENTER] to confirm your selection.

4Press [CAL] to bring up the calibration process

guidance. Follow the instructions to perform a calibration. For more information about calibration, refer to "Calibrate the N9330B before making

measurements" on page 25.

5 Remove the calibrator and connect the cable under

test (DUT) to the RF OUT connector on the top panel of the tester. The DTF measurement starts and the results are displayed on the screen. A peak in the horizontal trace indicates a defective location. 

NOTE

Measuring Distance to Fault (DTF)

For a more precise measurement, enter the cable loss and velocity factor information.

The measured distance and the displayed distance can be different. The measured distance refers to the distance the tester has measured according to the frequency ranges you specified. You can check the measured distance by pressing  {DTF Config} The displayed distance refers to that part of the entire measured distance chosen. The displayed distance may be manually set by pressing [FREQ/DIST] > {Start}, and {Stop}.

Measured distance

It is not always understood how frequency range affects measured distance and resolution, and may appears counter-intuitive. This section is intended to help simplify understanding the DTF measurement.

transmission rate relative to light. The velocity factor may be set by pressing {Velo Factor}.

• F2 and F1 refer to the stop and start frequency (MHz).

The measured distance (in meters) of a DTF measurement is determined by the following equation:

Distance= (Resolution x 150 x V

= 3 x 10

From this equation, you can adjust the measurement:

• To Increase the measured distance:

• Increase the number of points, 

• Reduce the frequency span.

• To decrease the measured distance:

• Reduce the number of points, 

• Increase the frequency span.

CAU-CAUTION

Making an Average Power Measurement

Average power measurements provide a key metric in transmitter performance.

Base station transmit power must be set accurately to achieve optimal coverage in wireless networks. If the transmit power is set too high due to inaccurate power measurements, undesired interference can occur. If the transmit power is set too low, coverage gaps or holes may occur. Either case may affect system capacity and may translate into decreased revenue for service providers.

Average power can be measured for the channel of interest while the base station is active. All other channels should be inactive. Average power is a broadband measurement. If other signals are present the analyzer will also measure their power contributions.

The maximum power for the RF IN port and the RF OUT port of the analyzer is +20 dBm. The maximum power for the Power Sensor port is +24 dBm. When directly coupled to a base station, the test set can be damaged by excessive power applied to any of these three ports.

To prevent damage in most situations when directly coupling an analyzer to a base station, use a high power attenuator between the analyzer and the BTS.

The analyzer supports the U2000 Series USB power sensors.

The U2000 Series USB power sensors do not need manual calibration and zero routines performed. Calibration and zeroing are performed without removing the power sensor from the source, through internal zeroing. With internal zeroing of U2000 Series USB

power sensors, there is no need to disconnect the sensor or power-off the DUT. The U2000 Series do not

require 50 MHz reference signal calibration, allowing the factory calibration to ensure measurement accuracy. For

best accuracy, users are recommended to perform

Page 41

Making an Average Power Measurement

NOTE

external zeroing for input signals below -30 dBm for best accuracy.

Making Measurements

If you suspect other signals may be present, it is recommended that you turn off all the other channels and measure average power only on the signal of interest. Another option is to measure channel power (which is less accurate), that filters out all other channels (signals). You can measure channel power for CDMA using the CDMA Analyzer or CDMA Over Air tool. For other modulation formats, use their respective analyzers (that is, GSM, 1xEV-DO, or W-CDMA) or measure channel power using either the spectrum analyzer or the Channel Scanner tool.

Connect the power meter as close as possible to the power amplifier/duplexer output. Do not use a coupled port. Sensors may not be as accurate at the power levels provided by coupled ports.

Making a Basic Average Power Measurement

To make an average power measurement, connect the power sensor and cable, zero and calibrate the meter, before making a measurement.

Zeroing of the Power Meter will occur automatically:

• Every time the Power Meter function is used.

• When a 5 degree C. change in instrument temperature occurs.

• Whenever the power sensor is changed.

• Every 24 hours (min.).

• Before measuring low level signals -for example, 10 dB above the lowest specified power the power sensor is capable of.

Calibrating the Power Meter every time you cycle the power on and off.

In most situations, you can press {Zero} to complete the two steps (zero and cal) together.

Using Markers and Pass/Fail Limit Lines

Markers and limit lines are used for measurement trace analysis.

Using markers

Markers are used to track the specified points on a trace. You may apply up to six markers and visually track up to six points on each trace. Each of the six markers has the following settings:

•On Activates a Marker and places a vertical, colored bar, with the Marker number ranging from M1 to M6 to the foot of the bar.

•Off Deactivates a marker and erases the Marker bar.

•Edit Brings up a dialog box and allows you to set the position of a marker.

Rotating the knob will move the position of a marker.

• Marker to Peak Places the active marker on the highest indicated value of the trace.

•Marker to Minimum Places the active marker on the lowest indicated value of the trace.

•Delta Is associated with the reference marker (Marker 1 is the default reference marker). Therefore, Marker 1 must be applied before creating the delta. Delta displays the value difference between the reference marker position and the delta marker position. Only one delta marker can be associated with a given reference marker.

Using Pass/Fail Limit Lines

Limit lines will alert the user to a measurement that exceeds the upper limit value of a trace. Limits are set in dB, and define the location of the limit lines displayed on the screen.

The tester applies upper limits only. Limit lines are used as pass/fail indicators:

• If the amplitude of a measured trace is below the limit line, a green Pass indicator is displayed in the upper right corner of the screen.

• If the amplitude of a trace is above a limit line, a red Fail indicator is displayed in the upper right corner of the screen. A limit fail beep sound can be turned on for an additional trace fail indicator.

Two types of limit lines

•Single limit A single limit value is applied over the full frequency range, 25 MHz to 4 GHz. A maximum of two single limit lines may be applied.

Processing Traces

NOTE

Trace overlap and trace operation are used in the tester for post trace processing. Very useful in comparing measurements to identify differences and faults.

Trace Operation

Trace operation mathematically adds or subtracts the current measured trace to a previously saved trace. This will provide information that may indicate when a cable or antenna system is degrading in performance and would require maintenance.i

The previously saved trace must have the same setup, with consistent measurement parameters as the current trace. For example, the same mode, resolution, and frequency/distance range.

Example: A saved a trace (data) has been entered into

the local memory of the tester. The trace was measured under return loss mode in GSM full band (880 MHz to 960 MHz), with 521 data points.

Perform the following steps for a trace operation:

1 Press [MEAS/VIEW] > {Trace Operation} to access the

check box for selecting a math operation mode:

• Trace – Memory

Current active trace mathematically subtracts the trace from local memory of the tester.

• Trace + Memory

Current active trace mathematically adds the trace from local memory of the tester.

2 Rotate the knob to select a mode and press [ENTER].

3 The tester brings up a list of existing trace data in the

local memory the tester.

4 Rotate the knob to select a trace that has the same

measurement mode, resolution and frequency range, and press [ENTER].

The tester displays the mathematically calculated trace on its screen.

Trace overlap

The tester allows a previously saved trace to be recalled onto the currently displayed screen. The two displayed traces are identified by different colors.

Trace overlap is a real-time tool for quick comparisons between the current trace and a previously saved trace. The tester cannot save the overlaid traces into either local memory or external USB memory stick.

The previously saved trace must have consistent  measurement parameters with the current trace. For example, the same mode, resolution, and frequency/distance range.

Example: To compare the current measurement trace to a saved trace (data) in the local memory of the tester. They were both measured in the return loss mode, GSM full band (880 MHz to 960 MHz), resolution 521 points.

Perform the following steps to do a trace overlap operation:

1Press [MEAS/VIEW] > {Trace Overlap} > {Select Trace}

to display a list of trace data stored in the local memory of the tester.

2 Use the front-panel knob to select a trace and press

[ENTER].

The tester will display the saved trace, while continuously making measurement of the DUT (current measured trace). The two traces are displayed on the screen simultaneously:

• Trace one is displayed as a static trace and is green

• Trace two is yellow in color and is repeatedly

in color. It is the saved trace results recalled from the local memory of the tester.

Enabling interference immunity

Other signals can interfere with Return Loss/SWR measurement. You can minimize the effect of the interference on the measurement by activating interference immunity in the tester.

Key access: [MEAS/VIEW] > {IIM}

Use of interference immunity increases the measurement time. Interference immunity should be used if a known interference signal exists or the Return Loss/SWR measurement displays suspicious characteristics, such as a spike or rapid movements in the noise floor.

Connector Care

Connectors quality is a critical link for a precision measurement. RF connectors are manufactured to extremely precise tolerances and must be used and maintained with care to protect the measurement accuracy and repeatability.

Taking proper care of cables and connectors will protect your tester’s ability to make accurate measurements. Inaccurate measurements often result of improper connections, dirty, or damaged connectors.

Worn, damaged, out of tolerance, or dirty connectors degrade the accuracy and repeatability of RF measurements.

Always take proper electrostatic precautions before touching the center conductor of any connector, or cable that is connected to the tester.

Page 59

Using Functions

CAU-CAUTION

Some Helpful Hints

Repeatability

If two identical measurements are made with the tester, the differences in the measured data should be so small that they do not affect the value of the measurement. Connector repeatability may be a cause of poor measurement results. Connector repeatability problems may be affected by:

• Dirty or damaged connectors

• Connections that have been made without using proper torque techniques (this applies when connections to the tester have been removed, then reconnected).

Extending the life of your cables and connectors

• Minimize the bending of test cables. A single sharp bend can damage a RF cable.

• Avoid repeated connection and disconnection of all RF cable connections.

• Do not bend cables at or near the RF connectors. This may affect the RF performance.

• Inspect all connectors for dirt, nicks, and other signs of damage or wear before connection. A bad connector can ruin a good connector instantly.

• Clean dirty connectors. Dirt and foreign matter can cause poor electrical connections, affect RF measurements, and may permanently damage the connectors.

Never exceed the recommended connector torque values when attaching cables or damage may result.
