Chapter 3 Getting Started Introduction This chapter provides a brief overview of the Anritsu Cell Master. The intent of this chapter is to provide the user with a starting point for making basic cable and antenna analyzer, spectrum analyzer, and power meter measurements. Procedures that are specific to cable and antenna analyzer mode (page 3-2), Spectrum Analyzer mode (page 3-10), and common to all modes (page 3-14) are presented.
Page 134: Cable And Antenna Analyzer Mode
Chapter 3 Getting Started Cable and Antenna Analyzer Mode Selecting the Frequency For the OSL or FlexCal calibration method the frequency range for the desired measure- ment must be set. The Cell Master will automatically set the frequency when a particular signal standard is selected, or the frequency can be manually set using the F1 and F2 soft keys.
Page 135 Chapter 3 Getting Started If a Test Port Extension Cable is to be used, the Cell Master must be calibrated with the Test Port Extension Cable in place. The Test Port Extension Cable is a phase stable cable and is used as an extension cable on the test port to ensure accurate and repeatable measure- ments.

Page 153: Chapter 4 - Cable & Antenna Analyzer Measurement Mode
Chapter 4 Cable & Antenna Analyzer Measurement Mode Introduction This chapter provides a description of cable and antenna analyzer measurements, including line sweeping fundamentals and line sweeping measurement procedures, available when the Cell Master is in frequency or DTF mode. Line Sweep Fundamentals In wireless communication, the transmit and receive antennas are connected to the radio through a transmission line.
Page 154: Cw Mode
Chapter 4 Cable & Antenna Measurements The performance of a transmission feed line system may be affected by excessive signal re- flection and cable loss. Signal reflection occurs when the RF signal reflects back due to an impedance mismatch or change in impedance caused by excessive kinking or bending of the transmission line.
Page 155: Information Required For A Line Sweep
Chapter 4 Cable & Antenna Measurements Use this feature with caution, as the later introduction of an interfering signal might be mis- taken for a problem with the antenna or cable run. If CW is on during a normal RL or SWR measurement, the Cell Master will be more sus- ceptible to interfering signals.
Page 156 Chapter 4 Cable & Antenna Measurements NOTE: The antenna must be connected at the end of the transmission feed line when conducting a System Return Loss measurement. Figure 4-2 is an example of a typical system return loss measurement trace using a FlexCal calibration: Figure 4-2.
Page 157 Chapter 4 Cable & Antenna Measurements Procedure - Cable Loss Mode Step 1. Press the MODE key. Step 2. Select using the Up/Down arrow key and press ENTER. Freq-Cable Loss Step 3. Set the start and stop frequencies, automatically by selecting a signal standard or manually using the F1 and F2 soft keys, as described on page 3-2.
Page 158 Chapter 4 Cable & Antenna Measurements Distance-To-Fault (DTF) Transmission Line Test The Distance-To-Fault transmission line test verifies the performance of the transmission line assembly and its components and identifies the fault locations in the transmission line system. This test determines the return loss value of each connector pair, cable component and cable to identify the problem location.
Page 159 Chapter 4 Cable & Antenna Measurements Step 10. Record the connector transitions. Figure 4-4 shows an example of a typical DTF return loss measurement trace using a FlexCal calibration. Figure 4-4. Typical DTF Return Loss Trace In the above example: Marker M1 marks the first connector, the end of the Cell Master phase stable Test Port Extension cable.
Page 160 Chapter 4 Cable & Antenna Measurements Increasing the data points increases the sweep time and increases the accuracy of the mea- surement. CW mode On or Off can also affect sweep speed (see CW Mode, page 4-2 for details). Antenna Subsystem Return Loss Test Antenna Subsystem return loss measurement verifies the performance of the transmit and receive antennas.

Page 162: Chapter 5 - Spectrum Analyzer Measurement Mode
Measurement Mode Introduction This chapter provides a description of Spectrum Analyzer measurements and procedures when the Cell Master MT8212B is in Spectrum Analyzer Mode. Measurement Fundamentals Measurement fundamentals include the use of additional spectrum analyzer functions be- yond frequency, span, amplitude and marker functions. In particular, this section focuses on resolution bandwidth, video bandwidth, sweep, and attenuator functions.
Page 163 Chapter 5 Spectrum Analyzer Measurements With a wide bandwidth, more noise is included in the measurement. With a narrow band- width, less noise enters the resolution bandwidth filter, and the measurement is more accu- rate. If the resolution bandwidth is narrower, the noise floor will drop on the display of the spectrum analyzer.
Page 164: Preamplifier
Chapter 5 Spectrum Analyzer Measurements IMPORTANT! Attenuation is normally a coupled function and is automatically adjusted when the reference level changes. The reference level does not change however, when the attenuator changes. The attenuator should be ad- justed so that the maximum signal amplitude at the input mixer is –25 dBm or less.
Page 165: Preamplifier Measurement Example
Chapter 5 Spectrum Analyzer Measurements Preamplifier Measurement Example This section provides an overview of how to detect a low-level signal with the help of the preamplifier of a MT8212B Cell Master. Required Equipment MT8212B Cell Master Test Port extension cable, Anritsu 15NNF50 – 1.5C A signal source (Anritsu 69xxxB Synthesized Signal Generator or equivalent) Procedure Step 1.
Page 166 Chapter 5 Spectrum Analyzer Measurements Figure 5-1 shows the measurement results with the preamplifier off. Figure 5-1. Preamplifier Off Step 14. Turn the preamplifier on. When the preamplifier is ON, the word should appear in the lower left corner of the display. The displayed noise level should be lowered by approximately 20 dB on the dis- play, and the signal should appear on top of the displayed noise.
Page 167: Dynamic Attenuation Control
Chapter 5 Spectrum Analyzer Measurements Dynamic Attenuation Control The dynamic attenuation control feature tracks the peak input signal level and automatically adjusts the attenuator to protect the MT8212B in situations of high RF signal levels. This feature also enhances the instrument sensitivity in situations of low-level RF signals by de- activating and activating the internal preamplifier resulting in improved measurement accu- racy.
Page 168: Selecting The Signal Standard And Channel
Chapter 5 Spectrum Analyzer Measurements Selecting the Signal Standard and Channel Before making measurements, the Cell Master must be set to the appropriate wireless net- work air interface standard and channel number. The most common standards and channel numbers are stored in the Cell Master and, when selected, the Cell Master automatically se- lects the correct frequency and span.
Page 169: Field Strength Measurements
Chapter 5 Spectrum Analyzer Measurements Field Strength Measurements All antennas have loss or gain that can cause errors in measurements. The Cell Master can correct for antenna loss or gain errors using Field Strength Measurements. The antenna fac- tors must be uploaded to the Cell Master using the Anritsu Handheld Software Tools pro- vided with the unit.

Chapter 5 Spectrum Analyzer Measurements AM/FM Demodulation The Cell Master built-in demodulator for AM, narrowband FM, wideband FM and single sideband (selectable USB and LSB) allows a technician to hear an interfering signal for easy identification. The demodulated signal can be heard using either the built-in speaker, or through a monaural headset connected to the 1/8-inch jack on the test panel.

Page 178: Carrier To Interference Ratio (C/I)
Chapter 5 Spectrum Analyzer Measurements Carrier to Interference Ratio (C/I) Carrier to Interference Ratio (C/I) Measurement is a two-step process, first measuring the carrier level and then, with the carrier turned off, measuring the remaining signals and noise in the band of interest. After the two measurements are complete, the ratio of the carrier level to the noise plus interference is displayed using three assumptions: The interferer is a narrowband frequency hopping signal source (NB FHSS) The interferer is a wideband frequency hopping signal source (WB FHSS)
