Line Sweep Fundamentals In wireless communication, the transmit and receive antennas are connected to the radio through a transmission line.
Page 148
4-2 Line Sweep Fundamentals Cable & Antenna Analyzer Measurements The performance of a transmission feed line system may be affected by excessive signal reflection 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.
Cable & Antenna Analyzer Measurements 4-3 CW Mode CW Mode CW mode can be used to maximize sweep speeds of both frequency and DTF measurements. With CW on, sweep times can be twice as fast as with CW off. However, making measure- ments with CW on will reduce the instrument’s immunity to interfering signals.

Measurement Mode Introduction This chapter provides a description of Spectrum Analyzer measurements and procedures when the LMR Master S412D is in Spectrum Analyzer Mode. Measurement Fundamentals Measurement fundamentals include the use of additional spectrum analyzer functions beyond frequency, span, amplitude and marker functions. In particular, this section focuses on resolution bandwidth, video bandwidth, sweep, and attenuator functions.
“smeared” look to it, with the spectral lines being wider than normal and shifted to the right. Fortunately, the Anritsu Handheld Spectrum Analyzer has mechanisms designed into it that relieve the user from having to calculate the sweep rate. When changing the RBW and VBW, the sweep rate will change accordingly.
Spectrum Analyzer Measurement Mode 5-3 Preamplifier Attenuator Functions Attenuation adjusts the hand held spectrum analyzer input attenuator. In Auto mode, as the reference level is increased, the attenuation is increased. In Manual mode, the input attenuation can be adjusted using the keypad or the Up/Down arrow key. The attenuator range is 0 to 51 dB, in 1 dB steps.
• S412D LMR Master • Test Port extension cable, Anritsu 15NNF50 – 1.5C • A signal source (Anritsu 69xxxB Synthesized Signal Generator or equivalent) Procedure 1. Press the MODE key and use the Up/Down arrow key to select the Spectrum Analyzer mode.

Spectrum Analyzer Measurement Mode 5-5 Preamplifier Measurement Example Figure 5-1 shows the measurement results with the preamplifier off. Figure 5-1. Preamplifier Off 14. Turn the preamplifier on. When the preamplifier is ON, the word AMP should appear in the lower left corner of the display. The displayed noise level should be lowered by approximately 20 dB on the display, and the signal should appear on top of the displayed noise.
5-6 Dynamic Attenuation Control Spectrum Analyzer Measurement Mode Dynamic Attenuation Control The dynamic attenuation control feature tracks the peak input signal level and automatically adjusts the attenuator to protect the S412D in situations of high RF signal levels. This feature also enhances the instrument sensitivity in situations of low-level RF signals by deactivating and activating the internal preamplifier resulting in improved measurement accuracy.
Spectrum Analyzer Measurement Mode 5-7 Selecting the Signal Standard and Channel Selecting the Signal Standard and Channel Before making measurements, the LMR Master can be set to the appropriate wireless network air interface standard and channel number. The most common standards and channel numbers are stored in the LMR Master and, when selected, the LMR Master automatically selects the correct frequency and span.
All antennas have loss or gain that can cause errors in measurements. The LMR Master can correct for antenna loss or gain errors using Field Strength Measurements. The antenna factors must be uploaded to the LMR Master using the Anritsu Master Software Tools provided with the unit.
The occupied frequency bandwidth is defined as the bandwidth between the upper and lower frequency points at which the signal level is XdB below the peak carrier level. Required Equipment • LMR Master S412D • Portable antenna for the selected signal frequency Procedure 1.

Chapter 17 — P25/LSM Talk-Out Coverage (Option 522) 17-1 Introduction The P25/LSM Talk-Out Coverage option allows the ability to graphically view signal strength or bit error rate of a single channel as a function of time and location. LMR Master combines the received signal information with time and location information from the internal GPS module (Option 31) to store data that can then be turned into coverage maps using 3rd party software.

17-1 Introduction P25/LSM Talk-Out Coverage (Option 522) 6. Select the RSSI vs Time or BER/MER vs Time (except for Pattern = None) to choose which trait will be displayed on the LMR Master. Both RSSI and BER/MER data is stored for every data point, regardless of which is displayed on the unit.
P25/LSM Talk-Out Coverage (Option 522) 17-2 Measurement Views 17-2 Measurement Views RSSI vs. Time Displays the Received Signal Strength Indicator of the selected frequency over time. The display shows the most recent 401 measured points, covering approximately 5 minutes, when synchronized to a P25-compatible signal.
17-2 Measurement Views P25/LSM Talk-Out Coverage (Option 522) BER vs. Time Displays the Bit Error Rate of the selected frequency over time, with the most recent data appearing at the right edge of the display. With the Pattern Select soft key, the LMR Master can detect bit error rates for the Standard 1011 Hz Tone or the Standard Transmitter Test (O.153/V.52) patterns.

The limit, which can be configured to be either an upper limit or a lower limit, is set for the entire graph.
Chapter 18 — NXDN Transmit Signal Analyzer (Option 530) 18-1 Introduction The NXDN Transmit Signal Analyzer option provides a method to verify the operation of NXDN tower, mobile, and portable radio transmitters. The option includes the ability to display constellation and histogram graphs, along with numeric display of received power, frequency error, modulation fidelity, symbol deviation, Radio Access Number (RAN), and bit error rate (BER) of the input signal.
