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 “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.
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.

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
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.
