Making Measurements Selecting a Measurement Mode Selecting a Measurement Mode Assuming you wish to make a return loss measurement, you need to: • Press the [MODE] hardkey to call up the mode selection check box. • Use the front-panel knob to select a measurement type from the Mode Select list.
Making Measurements Calibrate the N9330B before 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.
Making Measurements Calibrate the N9330B before making measurements 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...

Making Measurements Calibrate the N9330B before making measurements 3 Press [ENTER] to start calibration. Never connect an electronic calibrator to the tester until after NO TE 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.
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...
4 Press 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.
Follow the instructions to perform a calibration. For more information about calibration, refer to "Calibrate the N9330B before making measurements" on page 5 Remove the calibrator and connect the cable under test (DUT) to the RF OUT connector on the top panel of the tester.
Making Measurements 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 NO TE different. The measured distance refers to the distance the tester has measured according to the frequency ranges you specified.
Making Measurements Measuring Distance to Fault (DTF) 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. In the following equations: Resolution refers to the number of points that are measured and used in the displayed trace.
Making Measurements Making an Average Power Measurement 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.
Making Measurements Making an Average Power Measurement external zeroing for input signals below -30 dBm for best accuracy. If you suspect other signals may be present, it is NO TE recommended that you turn off all the other channels and measure average power only on the signal of interest.
Making Measurements Making an Average Power Measurement To Make a Basic Average Power Measurement You can follow the steps below to make a basic average power measurement. 1 Press [Preset] to perform a factory preset. 2 Press [MODE] > {Power Meter} > [ENTER] to turn on the power meter.

Using Functions Processing Traces Processing Traces 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...
Using Functions Processing Traces 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.
Using Functions Saving and Recalling a file Saving and Recalling a file N9330B allows you to save trace data, instrument setups, or the displayed screen graphic information into the local memory of the tester. With a USB memory stick inserted, you can also save trace data and screen copies into an external memory devices.
Limit lines, if activated, will be saved using Save Setup. Copy a screen The Keysight N9330B offers two methods to copy a screen: • Press [PRT SCR] to get a quick screen capture and save the file onto an external USB memory stick ONLY.
Using Functions Saving and Recalling a file Both of the methods allow you to save the currently displayed screen in JPEG format. Each screen copied is an 8-bit colored, 640×480 resolution graph. Copy screen will include any limit lines, if shown on screen. However, a screen shot is not editable.
