Chapter 2 — Spectrum Analyzer
2-1
Introduction
Spectrum analyzer measurements include the use of additional functions beyond frequency,
span, amplitude, and marker functions. Section 2-2 and Section 2-3 explain setup procedures
and settings for making spectrum analyzer measurements. Section 2-4 through Section 2-8
focus on resolution bandwidth, video bandwidth, sweep, attenuator, and detection functions.
Section 2-11 through Section 2-24 cover field measurements including brief examples
demonstrating field strength, occupied bandwidth, channel power, adjacent channel power
ratio, EMF, out-of-band spurious emissions, in-band/out-of-channel, AM/FM/SSB
demodulation, masks and carrier to interference ratio (C/I), coverage mapping, and
IQ waveform capture. Finally, Section 2-25 though Section 2-38 detail the submenus
available in Spectrum Analyzer mode.
2-2
General Measurement Setups
Refer to your instrument User Guide for instructions on setting up frequency, span,
amplitude, GPS, limit lines, markers, and file management.

Making Spectrum Analyzer Measurements
Required Equipment
• Optionally, an antenna that is appropriate for the frequency range to be measured
Required Setup
• Place the instrument in Spectrum Analyzer mode. Refer to “Selecting a Measurement
Mode” on page 1-1.
• Connect the input signal or antenna to the RF In test port.
Setting Frequency
The tuning frequency range can be entered in several different ways depending upon what
makes the most sense, either for the user or for the application. The center frequency and
span can be specified, the start and stop frequencies can be entered, or a signal standard and
channel number can be selected from the built-in list.
Offset Frequency
In addition, a user-defined frequency offset can be entered to adjust the frequency that is
displayed on the instrument from the actual swept frequency. For example, if the DUT is an
antenna system receiving signals in the 10 GHz range and offsetting the signals to the 1 GHz
range, you can set a frequency offset in the spectrum analyzer in order to display the actual
received antenna frequency in the sweep window. For a measurement example, see
Figure 2-39 on page 2-54.

Both positive and negative offset values are allowed. Negative offsets can be useful for seeing
differences from expected values. Enter a negative offset of the expected value, and the
received antenna frequency should display in the 0 Hz range.
When enabled, Offset is displayed at the bottom of the screen (Figure 2-39), and the
Center Freq, Start Freq, and Stop Freq submenu keys indicate that a frequency offset has been
turned on by adding the word Offset before Center, Start, and Stop. For menu examples, see
Figure 2-35 on page 2-49 and Figure 2-37 on page 2-52.
To remove a frequency offset, set the Freq Offset to 0 Hz.
Setting Bandwidth Parameters
Both resolution bandwidth (RBW) and video bandwidth (VBW) can be coupled to the
frequency span automatically or manually set. When set to Auto RBW, RBW adjusts
automatically in proportion to the frequency span. The default ratio of the span width to the
resolution bandwidth is 100:1, and can be changed as follows:
1. Press the BW main menu key.
2. Press the Span/RBW submenu key. The current Span/RBW ratio is shown as part of the
submenu key label. Change the value using the keypad, the directional arrows, or the
rotary knob and then press Enter.
When auto-coupling between the span and RBW is selected (the Auto RBW submenu key is
toggled to “On”), this is indicated on the left side of the display with the RBW label and
underneath it one to three digits followed by the frequency units; this represents the
resolution bandwidth value. If manual RBW is selected (the Auto RBW submenu key is
toggled “Off”), the label and value turn red and a ‘#’ symbol is shown in front of the RBW
label. Adjust resolution bandwidth independently of the span. If an unavailable resolution
bandwidth is entered, then the instrument selects the next higher resolution bandwidth. If a
value greater than the widest RBW is entered, then the widest RBW will be selected.
VBW can be set two ways – manually or by auto coupling. Auto coupling of the VBW links the
video bandwidth to the resolution bandwidth, so that VBW varies in proportion to RBW. Auto
coupling is indicated on the left side of the display with the VBW label and underneath it one
to three digits and the frequency units; this represents the video bandwidth value. If manual
VBW coupling is selected, the label and value turn red and the “#” symbol is shown in front of
VBW on the left side of the display. Adjust video bandwidth independently of the RBW. If a
non-existent video bandwidth is entered, then the instrument will select the next higher
video bandwidth. If a value greater than the widest VBW is entered, then the widest VBW
will be selected.
The ratio of the resolution bandwidth to the video bandwidth can be changed by pressing the
BW main menu key, the RBW/VBW submenu key, and then using the keypad, the directional
arrows, or the rotary knob to set the ratio. By default, the RBW/VBW ratio is set to 3.
The current value of the ratio is shown as part of the submenu key label.
1. Press the BW main menu key.
2. Press the RBW/VBW submenu key. The current RBW/VBW ratio is shown as part of the
submenu key label. Enter the desired value.
The RBW range varies with instrument features. Refer to the RBW submenu key description
in “BW (Bandwidth) Menu” on page 2-59, and check your Technical Data Sheet for the RBW
range of your instrument.

Setting Sweep Parameters
To set the sweep parameters, press the Shift key followed by the Sweep (3) key.
Single/Continuous
When this submenu key is pressed, the instrument toggles between single sweep and
continuous sweep. In single sweep mode, the instrument waits until the Sweep Once
submenu key is pressed or another triggering mode is selected.
Sweep Mode
Several sweep modes are available on the instrument. Press the Sweep Mode submenu keys
to select between Fast (default), Performance, No FFT, or Burst Detect. Note that Burst Detect
is supported on MS2720T and MT8220T instrument models only.
Improperly installed cellular boosters can sometimes produce burst interference. By using
Burst Detect mode when available, a narrow pulsed or burst signal is easily seen in spectrum
analyzer mode, capturing emitters as narrow as 200 μs. Burst Detect works in a maximum
span of 15 MHz.
Figure 2-1 shows two traces. The yellow trace is the live trace with Burst Detect sweep mode,
while the green trace is a max hold trace. There is not much difference between the two
traces, thus, max hold is no longer needed in order to see narrow pulsed signals.

The Show Help submenu key displays a table detailing the trade-off between sweep speed and
performance of the sweep mode options..
Note
Sweep Mode menu functionality varies based on instrument model. Fast is the
default sweep mode for instruments that have received the new instrument
calibration from Anritsu.
Trigger Type
To select a specific type of triggering in zero span, press the Triggering submenu key followed
by the Source submenu key. Selections are:
Free Run: The default trigger type is “Free Run” in which the instrument begins
another sweep as soon as one is finished.
External: A TTL signal applied to the External Trigger BNC input connector causes a
single sweep to occur. This mode is used in zero span, and triggering occurs on the
rising edge of the signal. After the sweep is complete, the resultant trace is displayed
until the next trigger signal arrives.
Video: This mode is used in zero span to set the power level at which a sweep is
initiated. The power level can be set from –130 dBm to +30 dBm. Trigger is based on
the measured signal level. The sweep triggers when the signal level crosses the trigger
level with a positive slope. If no signal crosses the trigger level, the last trace on the
screen, before video triggering was selected, will be displayed. To change the video
triggering level use the rotary knob, enter the desired amplitude with the keypad, or
use the left or right arrows to change the setting by 1 dB or the up or down arrows to
change the setting by 10 dB.
IF Power (available on MS2720T model only): This mode is used in zero span to set IF
power level as the trigger source. The power level can be set from –130 dBm to
+30 dBm, using the rotary knob, arrow keys, or keypad. The trigger is based on the
measured signal level. If no signal reaches or exceeds the trigger level, then no trace
will be displayed on the screen.
Zero Span IF Output (Standard or Option 89): Zero Span IF Output provides an IF signal
that is nominally at 140 MHz out of a BNC female connector labeled IF Out 140 MHz or
IF Out (option) 140 MHz.
Notes
The IF output signal is present only when the spectrum analyzer Span is set to
zero and the Zero Span button has been pressed a second time to bring up the IF
bandwidth menu (refer to “Zero Span IF BW Menu (Option 89)” on page 2-58). The
key sequence is: Span > Zero Span > Zero Span.
MS2723B and MS2724B instruments use IF frequency of 37.8 MHz rather than the
140 MHz of other Anritsu Spectrum Masters. IF output bandwidth is limited to
16 MHz. For these MS2723B and MS2724B instruments, the BNC connector is
labeled IF Out 37.8 MHz.
You can select Normal or any one of four fixed IF bandwidths of 7 MHz, 10 MHz, 16 MHz, or
32 MHz. In Normal, the bandwidth is set by the spectrum analyzer RBW selection (BW > Zero
Span RBW). When Normal is selected, the IF bandwidth is influenced by the selection of RBW
filters, although the digital RBW filters themselves are not employed.

Making Spectrum Analyzer Measurements
Zero Span IF output effectively uses the spectrum analyzer as a receiver front-end,
converting the input signal at the spectrum analyzer RF In connector to a signal centered at
140 MHz out of the IF Out 140 MHz connector. You can then process the IF signal in a way
that meets your needs. That may mean using an A-to-D converter or some other signal
processing method. An anti-aliasing filter can be employed in the signal processing to reduce
the effect of noise and spurious signals. A filter centered on 140 MHz with a bandwidth
slightly wider than 32 MHz is also advised to eliminate any undesired out-of-band signals on
the IF output. In particular, signals at 100 MHz and its harmonics (that would be eliminated
by the filter) are on the IF output.
When IF output is turned on by setting the instrument to zero span , then pressing the Zero
Span submenu key a second time displays the Zero Span IF Bandwidth menu (Figure 2-2).
The selectable bandwidth values may differ among instrument types. This figure is typical.

Zero Span IF Bandwidth Selection Menu
The Normal IF BW choice selects a bandwidth that uses analog bandpass filters in the normal
RBW chain. By changing the RBW, different filter bandwidths are selected.
The spectrum analyzer has several mixer bands. Depending on the operating frequency,
the local oscillator may be above or below the input frequency. When the local oscillator
frequency is below the input frequency, an increase in the input frequency results in an
increase in the IF output frequency. When the local oscillator is above the input frequency, an
increase in the input frequency moves it closer to the local oscillator frequency and the IF
output frequency consequently decreases. Table 2-1 on page 2-6 shows the bands and
indicates where the LO frequency is, in relation to the RF frequency.

“Inverted” means that the IF is spectrally inverted from the input (as the input
frequency goes higher, the IF goes lower).
“Not Inverted” means that the IF is not spectrally inverted (as the input frequency goes
higher, the IF goes higher).
You need to take frequency inversion into account when processing the IF signal. Assuming
that the IF has been processed to yield I and Q data, inversion is easily done by swapping
I and Q.
A residual frequency offset of the IF may exist compared to the RF due to the resolution of the
first and second local oscillators, as well as the calibration of the IF filters. This offset is
usually on the order of several kHz, but may be up to 10 kHz or so if the narrowest IF filters
are selected. To determine the residual offset, you need a second spectrum analyzer or a
frequency counter.
1. Attach a signal source (or antenna) to the spectrum analyzer and set the center
frequency to the center of the signal being received.
2. Press BW then Zero Span, and then press Zero Span a second time to turn on the
IF output.
3. Attach a second spectrum analyzer to the IF output and set the center frequency to
140 MHz. Set the span of the second spectrum analyzer to 100 kHz or less to have the
resolution needed to be able to measure an offset that may be 25 kHz or less.
4. Measure the frequency of the IF signal to see how far the signal is offset from 140 MHz.

Gated Sweep (Option 90)
To set up the instrument for gated sweep measurements, press the Gated Sweep Setup key
under the Sweep menu. The instrument screen changes to a dual graph view that makes it
easier to set up the Gate Length and Gate Delay using the time domain/zero span view in the
bottom graph while simultaneously viewing the signal spectrum in the top graph. The Gate
Length is represented by the width of the displayed blue dashed rectangle. See Figure 2-3.
This is useful for measuring signals in the time domain such as pulsed RF, time multiplexed,
or burst modulated signals.
The Gate Source selected determines the trigger source from which the gate is controlled. Not
all instrument models and options support all triggering selections. (Refer to “Gate Setup
Menu” on page 2-67.) Gate Polarity controls the triggering edge of the selected triggering
source.
The Gate View Settings key brings up a submenu where you can independently set the Zero
Span RBW, Zero Span VBW, and Zero Span Time. Zero Span Time controls the time scale of
the Gate View graph.
Figure 2-3.
Gated Sweep Example - External Gate Source
Once the gate has been set up, you can apply gating to the spectrum by setting Gated Sweep
to On. Gating will continue to be applied when you press Back and access other
measurements and functions of the spectrum analyzer until either: (1) Gated Sweep is
explicitly set to Off or (2) the Span setting is changed to Zero Span. Gated Sweep is not
allowed in Zero Span mode.

Resolution Bandwidth
Spectrum Analyzer
Resolution Bandwidth
Resolution Bandwidth (RBW) determines frequency selectivity. The spectrum analyzer traces
the shape of the RBW filter as it tunes past a signal. The choice of resolution bandwidth
depends on several factors. Filters take time to settle. The output of the filter will take some
time to settle to the correct value, so that it can be measured. The narrower the filter
bandwidth (resolution bandwidth), the longer the settling time needs to be, and therefore, the
slower the sweep speed.
The choice of resolution bandwidth will depend upon the signal being measured. If two
closely-spaced signals are to be measured individually, then a narrow bandwidth is required.
If a wider bandwidth is used, then the energy of both signals will be included in the
measurement. Thus, the wider bandwidth does not have the ability to look at frequencies
selectively, but instead simultaneously measures all signals falling within the resolution
bandwidth. Therefore, a broadband measurement would include all signals and noise within
the measurement bandwidth into a single measurement.
On the other hand, a narrow-band measurement will separate the frequency components,
resulting in a measurement that includes separate peaks for each signal. There are
advantages to each. The ultimate decision will depend upon the type of measurement
required.
There is always some amount of noise present in a measurement. Noise is often broadband in
nature; that is, it exists at a broad range of frequencies. If the noise is included in the
measurement, the measured value could be in error (too large) depending upon the noise
level. With a wide bandwidth, more noise is included in the measurement. With a narrow
bandwidth, less noise enters the resolution bandwidth filter, and the measurement is more
accurate. If the resolution bandwidth is narrower, the noise floor will drop on the spectrum
analyzer display. As the measured noise level drops, smaller signals that were previously
obscured by the noise can now be measured.
2-5
Video Bandwidth
Spectrum analyzers typically use another type of filtering after the detector called video
filtering. This filter also affects the noise on the display but in a different manner than the
resolution bandwidth. In video filtering, the average level of the noise remains the same, but
the variation in the noise is reduced. Hence, the effect of video filtering is a “smoothing” of the
signal noise. The resultant effect on the analyzer’s display is that the noise floor compresses
into a thinner trace, while the average position of the trace remains the same.
Changing the video bandwidth (VBW) does not improve sensitivity, but it does improve
discernability and repeatability when making low-level measurements. As a general rule,
most field spectrum analyzer measurements are made at a video bandwidth that is a factor
of 10 to 100 less than the resolution bandwidth. This ratio can be specified in the BW main
menu. Using this ratio, with a resolution bandwidth of 30 kHz, typically, the video bandwidth
is set between 300 Hz and 3 kHz, although it can be set anywhere from 1 Hz to 10 MHz.

Sweep Limitations
Sweep Limitations
With some spectrum analyzers, the user has control over sweep time (the elapsed time of each
sweep, sometimes called scan time). An analyzer cannot be swept arbitrarily fast while
maintaining its specified accuracy, but will have a sweep rate limitation depending upon the
resolution bandwidth, video bandwidth, and frequency range selected. The sweep rate is not
usually chosen by the user but is determined by the frequency range swept divided by the
sweep time. The limitation on sweep rate comes from the settling or response time of the
resolution and video bandwidth filters. If an analyzer is swept too quickly, the filters do not
have time to respond, and the measurement is inaccurate. Under such conditions, the
analyzer display tends to have a “smeared” look to it, with the spectral lines being wider than
normal and shifted to the right and at a lower amplitude than is correct.
Anritsu products are designed to relieve the user from having to calculate the sweep speed or
experiment to discover a sweep speed that yields accurate results. When changing the RBW
and VBW, the sweep speed automatically changes to the fastest sweep speed that will yield
accurate results. The sweep speed will be faster for a wide RBW or VBW and slower for a
narrow RBW or VBW. The sweep speed can also be changed manually, by pressing the Sweep
key and selecting the Sweep Time submenu key. Enter a sweep time from 10 μs to
600 seconds. If the minimum sweep time entered by the user is less than the value needed to
assure accurate results, the value that delivers accurate results will be used. Regardless of
the minimum sweep time setting, the instrument will never sweep faster than the RBW and
VBW settings will allow. The instrument is designed to ensure that no uncalibrated
measurement conditions will occur.
2-7
Attenuator Functions
The Spectrum Analyzer includes a step attenuator at the RF input. This attenuator is used to
reduce large signals to levels that make best use of the analyzer’s dynamic range. Normally,
the input attenuation automatically adjusts as a function of Reference Level. In the
Amplitude menu, the Attn Lvl key allows manual adjustment of the input attenuation, using
the numeric keypad, the Up/Down arrow keys, or the rotary knob. In Auto Atten mode, as the
reference level is increased, the attenuation is increased.
The following actions, listed in decreasing order of effectiveness, can facilitate the
detection of low-level CW signals:
1. Decrease the reference level and attenuation. Refer to “Amplitude Menu”
on page 2-55.
Note
2. Turn on the Preamp.
3. Reduce RBW. Refer to “BW (Bandwidth) Menu” on page 2-59.
4. Decrease VBW (RBW/VBW = 10 is often optimal for this purpose).
5. Use trace averaging if VBW is already set to 1 Hz.

Detection
Spectrum Analyzer
Detection
Several detection methods tailor the performance of the instrument to meet specific
measurement requirements. In general, several measurement points are calculated for each
display point. The various detection methods are different ways of dealing with how
measurement point data is shown at each display point. Refer to “Units & Detection Menu”
on page 2-56.
Peak: This method causes the largest measurement point to be shown for each display
point, and ensures that a narrow peak is not missed.
RMS/Avg: This method performs a root-mean-square calculation of all the
measurement points in each display point. This is particularly useful in displaying the
average value of noise or noise-like signals.
Negative: This method causes the smallest measurement point to be shown for each
display point. It is especially useful in zero span, to see if the signal amplitude drops
briefly. The method is also useful when looking at modulated signals, to see if some
frequencies are not being used.
Sample: This is the fastest detection method because for each display point, only one
frequency point is measured. Use this method when speed is of paramount importance
and the possibility of missing a narrow peak is not important.
Quasi-peak: When this selection is made, resolution bandwidths and video bandwidths
of 200 Hz, 9 kHz and 120 kHz are available. This detection method is designed to meet
CISPR requirements. (Not available in zero span.)

Power density to field strength:
An alternate measure of field strength is power density:
Pd = E2 / 120π
where:
E = field strength in V/m
Pd = Power density in W/m2
Power density at a point:
Pd = PtGt / (4πr2)
where:
Pd = power density in W/m
Pt = power transmitted in Watts
Gt = gain of transmitting antenna
r = distance from the antenna in meters
This equation is only valid in the far field, where electric and magnetic fields are related by
the characteristic impedance of free space.

Occupied Bandwidth Measurement
Occupied Bandwidth (OBW) is a common measurement performed on radio transmitters.
This measurement calculates the bandwidth containing the total integrated power occupied
in a given signal bandwidth. There are two different methods of calculation depending upon
the technique used to modulate the carrier.
• % Integrated Power Method: The occupied frequency bandwidth is calculated as the
bandwidth containing the specified percentage of the transmitted power.
• > dBc Method: The occupied frequency bandwidth is defined as the bandwidth
between the upper and lower frequency points at which the signal level is a desired
number of dB below the peak carrier level.

Channel Power Measurement
Channel power measurement is one of most common measurements for a radio transmitter.
This test measures the output power, or channel power, of a transmitter over the frequency
range. Out-of-specification power measurements indicate system faults, which can be in the
power amplifiers or in filter circuits. Channel Power measurements can be used to validate
transmitter performance, comply with government regulations, or to keep overall system
interference at a minimum.

Channel Power Measurement for GSM
Global Systems for Mobile (GSM) communication is a globally accepted standard for digital
cellular communication. A number of frequency bands that are allocated to GSM mobile
phones use a combination of Frequency Division Multiple Access (FDMA) and Time Division
Multiple Access (TDMA). Within each band, are approximately one hundred available carrier
frequencies on 200 kHz spacing (FDMA), and each carrier is broken up into time-slots so as to
support eight separate conversations (TDMA). GSM uses the Gaussian Minimum Shift
Keying (GMSK) modulation method.

In-Band/Out-of-Channel Measurements
Spectrum Analyzer
In-Band/Out-of-Channel Measurements
The in-band/out-of-channel measurements are used to determine the distortion and
interference within the system band, but outside of the transmitting channel. These
measurements include in-band spurious emissions and adjacent channel power ratio (also
called spectral regrowth). There are stringent regulatory controls on the amount of
interference that a transmitter can spill to neighboring channels. To determine compliance
with the allowable level of spurious emissions, two parameters need to be specified:
• Measurement channel bandwidth
• Allowable level of spurious emissions
The measurements described in this section are distinct from the built-in emission mask
(in-band) measurements that are performed via the Masks and C/I submenu. See “Emission
Mask (In-Band)” on page 2-29.

AM/FM/SSB Demodulation
AM/FM/SSB Demodulation
The built-in demodulator for AM, narrowband FM, wideband FM, and single sideband
(selectable upper sideband (USB) and lower sideband (LSB) signals) allows a technician to
hear an interfering signal. The demodulated signal can be heard using either the built-in
speaker or a monaural headset connected to the 2.5 mm jack on the connector panel.
Procedure
1. Press the Shift key followed by the Measure (4) key. Then press the AM/FM Demod
submenu key.
2. Press the Demod Type submenu key and press FM Wide Band, FM Narrow Band, AM,
USB, or LSB to match the modulation format of the signal.
3. Press the Back submenu key.
4. Press the Demod Freq submenu key and use the keypad or rotary knob to enter the
center frequency of the signal to be demodulated. For USB and LSB signals, fine tune
the signal by adjusting the Beat Freq Osc. By default the BFO frequency is set to zero,
meaning that the re-injected carrier is exactly at the demodulation frequency. The
Beat Freq Osc submenu key allows adjustment of the beat frequency oscillator to fine
tune the signal through a span of ± 10000 Hz.
5. Press the On/Off submenu key to enable the demodulation.
6. Press the Volume submenu key and use the up or down arrow keys or the rotary knob to

Spectrum Analyzer
Carrier to Interference Ratio Measurement
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 (NB FHSS)
• The interferer is a wideband frequency hopping signal (WB FHSS)
• The interferer is a broadband signal (BB).
The primary application for this type of measurement is determining the magnitude of
interference problems for 802.11b, 802.11g and 802.11a access points (hot spots).
Procedure
1. Press the Freq main menu key followed by the Signal Standard submenu key. Select the
appropriate signal standard based on the signal to be measured and press Enter.
2. Press the Channel submenu key, select the operating channel of the access point being
measured and press Enter.
3. Press the Shift key followed by the Measure (4) key. Then press the Masks and C/I
submenu key, and then the C/I submenu key.
4. Press the Center Freq (or Offset Center Freq) submenu key and enter the desired
frequency, unless a Signal Standard and Channel have already been selected in the
Frequency menu.
5. If needed, press the Span submenu key and set an appropriate span width for the signal
to be measured.
6. If the signal environment includes slow frequency hopping signals, such as cordless
telephones, press the Sweep Time submenu key to set a sweep time of one second or
more to give a good chance of capturing instances of the interfering signal. The
minimum sweep time for a valid measurement is displayed in the Min Sweep Time
submenu key.
7. Press the On/Off submenu key and follow the on-screen prompts to complete the
measurement.
Note
Access to the transmitter is required to complete this procedure as the transmitted
carrier must be turned off for the second portion of the measurement.
8. After the measurement is complete, the measurement box gives results for the three
different signal types. Some measurement results may show as Error, and this is to be
expected.

IQ Waveform Capture (Option 24)
Option 24, IQ Waveform Capture, captures the raw data for the set center frequency and for
the duration of the set capture length. This section includes instructions for setting up the
instrument, capturing a waveform, and saving it to the instrument, or using the MATLAB
script to read the captured waveform and to save it to a PC.
For remote setup and waveform capture, please refer to the Programming Manual for your
instrument. It includes SCPI commands for instrument remote control, waveform set up and
capture, and two sample scripts: MATLAB and C++. The MATLAB script is used to read a
WCAP file from the instrument and unpack the data into a MATLAB array. The C++ sample
program uses the SCPI commands to initiate a capture and save it directly to the PC.
Waveform Capture Setup
1. Press the Shift key and then the Measure (4) key on the instrument to open the
Measure menu.
2. Press the IQ Waveform Capture submenu key (which is displayed only if Option 24 is
installed on your instrument) to open the IQ Waveform Capture menu.

Center Freq: Press the Freq main menu key followed by the Center Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If entering a frequency using the keypad, the
submenu key labels change to GHz, MHz, kHz, and Hz. Press the
appropriate units key. Pressing the Enter key has the same effect as the MHz
submenu key.
Note: When using the up and down arrows, the frequency moves in steps
defined by the value entered using the Freq Step submenu key. When using
the left or right arrow keys, the frequency of the active parameter moves by
10% of the current frequency span. If the instrument is in zero span, the left
and right arrows do nothing. Turning the rotary knob changes the active
frequency parameter in increments of one display point for each click of the
knob. There are 551 display points across the screen.
Start Freq: Press the Freq main menu key followed by the Start Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If a start frequency higher than the current stop
frequency is entered, the stop frequency will be changed to yield a
10 Hz span.
Stop Freq: Press the Freq main menu key followed by the Stop Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If a stop frequency lower than the current start
frequency is entered, the start frequency will be changed to yield a
10 Hz span.
Span: Press the Freq main menu key followed by the Span submenu key
and enter the desired span. The Span menu is used to set the frequency
range over which the instrument will sweep. The span can be set from 10 Hz
to the maximum frequency range the product will support. See the product
specifications for the maximum frequency. Span can also be set to zero span.
The submenu key shows the current value for span in units
of GHz, MHz, kHz, or Hz. When the Span button is pressed, span becomes
the active parameter and may be changed. Use the keypad, the directional
arrow keys, or the rotary knob to increase or decrease the span frequency. If
the span is changed using the arrow keys, the span changes in 1-2-5 steps
for each key press. See “Span Menu” on page 2-57.

Auto Atten On/Off: Input attenuation can be either tied to the reference
level (On) or manually selected (Off). When input attenuation is tied to the
reference level, attenuation is increased as higher reference levels are
selected to make sure the instrument input circuits are not saturated by large
signals that are likely to be present when high reference levels are required.
Atten Lvl: Press this submenu key and use the numeric keypad, the rotary
knob, or the arrow keys to change the attenuation value.
RL Offset xx dB Ext Gain/Loss: RL Offset compensates for the presence
of external input attenuation or gain. Enter a positive value to compensate for
gain or loss, then press the appropriate submenu key (dB External Gain or dB
External Loss). The new RL Offset value will be displayed on the button.
Pre Amp On/Off: This submenu key turns the low-noise front-end
preamplifier on or off. To ensure accurate measurement results, the largest
signal into the instrument input when the preamplifier is turned on should be
less than –40 dBm.
Units & Detection: Press this submenu key to open the “Units & Detection

Strength, values may be displayed in dBm/m2, dBV/m, dBmV/m, dBµV/m,
Volt/m, Watt/m2, dBW/m2, A/m, dBA/m, or Watt/cm2. See Figure 2-24
on page 2-39. Press Back to return to the Amplitude menu.
Detection: Several detection methods tailor the function of the instrument
to meet specific measurement requirements. There are often more
measurement points across the screen than display points. The various
detection methods are different ways of dealing with how measurement
points will be shown at each display point. The Detection submenu is
illustrated on the lower left.
Back
Detection
Peak
RMS/Avg
Negative
Sample
Quasi-peak
Peak: This method causes the largest measurement point to be
shown for each display point, assuring that a narrow peak is not
missed.
RMS/Avg: In the Preset case, when the VBW/Average Type is set to
Linear, this method detects the average power of measurement points
that go into the display point. When VBW/Average Type is set to Log,
the traditional average of log(power), such as dBm, is displayed for
the detector, as well as for VBW and trace average.
Negative: This method causes the smallest measurement point to be
shown for each display point. It is especially useful in zero span, to
see if the signal amplitude drops briefly. The method is also useful
when looking at modulated signals, to see if some frequencies are not
being used.
Sample: This is the fastest detection method because for each
display point, only one frequency point is measured. Use this method
when speed is of paramount importance and the possibility of missing
a narrow peak is not important.
Quasi-peak: When this selection is made, resolution bandwidths and
video bandwidths of 200 Hz, 9 kHz and 120 kHz are available. This
detection method is designed to meet CISPR requirements.

Zero Span
Span: This submenu key shows the current value for span in units
of GHz, MHz, kHz, or Hz. When the Span button is pressed, span becomes
the active parameter and may be changed. Use the keypad, the directional
arrow keys, or the rotary knob to increase or decrease the span frequency.
If the span is changed using the arrow keys, the span changes in a 1-2-5
sequence for each key press.
Span Up 1-2-5: This is a convenient way to quickly arrive at a wider span
value. The first time the submenu key is pressed, the span value increases to
the nearest even value that starts with 1, 2, or 5. For example, if the span is
1.8 MHz, then pressing the submenu key for the first time changes the span
to 2.0 MHz, and the next press takes the value to 5.0 MHz, and so on.
Span Down 1-2-5: This is a convenient way to narrow the frequency span.
The first time the submenu key is pressed, the span value decreases to the
nearest even value that starts with 1, 2, or 5. For example, if the span is
1.8 MHz, then pressing the submenu key for the first time changes the span
to 1.0 MHz, and the next press takes the value to 500 kHz, then 200 kHz, and
so on.
Full Span: Pressing this button sets the span to cover the entire tunable
spectrum of the instrument.
Zero Span: This submenu key sets zero span. In this mode, the display
shows amplitude changes at a single frequency. This function is frequently
used to allow the easy monitoring of power variations over time. For example,
if information about the amplitude of an 802.11a access point signal is
needed, then the access point frequency would be set as the center
frequency, resolution bandwidth would be set to a value wide enough to
encompass as much of the signal as possible, and the tester would walk
around the access point usable area while the instrument records the
amplitude using slow sweep.
Zero Span (Option 89): If Option 89 is installed on your instrument, press
the Zero Span key again (after the circle is red) to access the “Zero Span
IF BW Menu (Option 89)” on page 2-58.
Last Span: This submenu key returns the span to the most recent span
value immediately before a change was made.
Back: Returns to the previous menu.

to RBW can be specified using the Span/RBW submenu key.
VBW: The current video bandwidth value is displayed in this submenu key.
The key displays the Zero Span VBW if Zero Span is selected. The VBW can
be changed using the keypad, the arrow keys, or the rotary knob. Bandwidth
values increment in a 1 to 3 sequence, from 1 Hz to 3 Hz to 10 Hz, or from
10 Hz to 30 Hz to 100 Hz, for example. Refer to your instrument Technical
Data Sheet for the video bandwidth range.
Auto VBW On/Off: When Auto VBW is On, the instrument selects the video
bandwidth based on the resolution bandwidth. The ratio of video bandwidth to
resolution bandwidth can be set using the RBW/VBW submenu key.
VBW/Average Type: Toggles between Linear averaging (arithmetic mean)
and Logarithmic averaging (geometric mean).
RBW/VBW: This submenu key displays the ratio between resolution
bandwidth and video bandwidth. To change the ratio, press this submenu key
and use the keypad, the arrow keys, or the rotary knob to select a new ratio.
The default ratio is 3. When the quasi-peak detector is selected the
RBW/VBW ratio is changed to 1.
Span/RBW: This submenu key displays the ratio between the span width
and the resolution bandwidth. The default value is 100, meaning that the span
width is approximately 100 times the resolution bandwidth. The value is
approximate because resolution bandwidth filters come in discrete steps
while span width can be set to any value up to the maximum span of the
instrument. To change the ratio, press this submenu key and use the keypad,
the arrow keys, or the rotary knob to select a new ratio.

occurred.
Use the numeric keypad, rotary knob, or arrow keys to change the delay
value. When using the numeric keypad, the Units menu is displayed. Press
the appropriate key to enter the trigger delay value as a percentage of the
sweep time or a fixed value in units of ns, μs or ms.
A negative delay displays the trigger position on screen, while a positive
value places the trigger point off the screen to the left.
Level: Sets a trigger level to initiate a measurement when Video or IF Power
is selected in the “Trigger Source Menu” on page 2-66. Press this key, then
use the rotary knob, arrow keys, or numeric keypad to enter the trigger power
level. The value ranges from –150 dBm to +30 dBm.
Slope: Sets the trigger slope to rising or falling.
Hysteresis: When used, value unit is in dB. Hysteresis can be used with
Level and Slope when setting a measurement trigger. Hysteresis is used to
prevent undesired triggering when the signal is hovering near the trigger
value. For example, the Level is set to 10 dBm, the Slope is set to Rising,
and Hysteresis is 1 dB. The first trigger occurs when the signal reaches at
least the 10 dBm level. To trigger again, the signal must drop below 9 dBm
before returning to 10 dBm. For another example, with Level set to 10 dBm,
slope set to Falling, and Hysteresis set to 1 dB, the opposite must occur to
activate a trigger. The signal amplitude falls and a trigger occurs when the
signal reaches the 10 dBm level. The signal must then reach at least 11 dBm
before falling to 10 dBm and initiating a trigger.
Holdoff: Delays the next trigger to the time set regardless of triggers
occurring within the set time.
Force Trigger Once: Forces a sweep regardless of meeting any trigger
criteria.

Ref Power Peak/Channel: Press this submenu key to toggle between the
Peak and Channel settings. When Peak is selected, the mask is moved up or
down so that the mask value at the center frequency is the same as the peak
value of the trace. When Channel is selected, the reference power value is
the same as would be calculated by the Channel Power measurement, over
the defined channel width; in this case, the mask value at the center
frequency is moved to the channel power measurement result.
Channel Width: Channel Width is preset within the Signal Standard. Press
this submenu key, then use the directional arrow keys, rotary knob, or
numeric keypad to adjust the channel width as desired.

math is active, a relative scale shows on the right side of the graph, and is
associated to Trace C. This allows the user to optimize the display of Trace C
without affecting the display of Trace A and Trace B.
Relative Ref: Sets the value applied to the top graticule for the relative scale
that appears on the right side of the graph when trace math is active. Change
this value by using the rotary knob, up or down arrows, or entering the value
on the numeric keypad and pressing the dB submenu key or the Enter key.
This entry is valid only when trace math is active
Relative Scale: Sets the value applied to the scaling of the relative scale that
appears on the right side of the graph when trace math is active. Change this
value by using the rotary knob, up or down arrows, or entering the value on
the numeric keypad and pressing the dB submenu key or the Enter key. This
entry is valid only when trace math is active.

The Limit menu keys are shown in the following figures.
Two types of limit lines can be specified, lower limit lines and upper limit lines. Limit lines
can be used for visual reference only, or for pass/fail criteria by using the limit alarm
(Figure 2-81). Limit alarm failures are reported whenever a signal is above the upper limit
line or below the lower limit line. By using save-on-event, a signal that exceeds the limit
alarm can be automatically saved. For details, see the User Guide for your instrument.
Each limit line can consist of a single segment, or as many as 40 segments across the entire
frequency span of the instrument. These limit segments are retained regardless of the current
frequency span of the instrument, which allows the configuring of specific limit envelopes at
various frequencies of interest without having to re-configure them each time the frequency is
changed.
Limit Upper/Lower: This submenu key selects which limit line will be active
for editing. The limit line that is currently selected for editing is underlined.

Limit Envelope: A limit envelope is very useful when you want to easily detect
new signals in the presence of other preexisting signals. Use the limit envelope
function to automatically create upper or lower limit lines that are based upon
the on-screen measured spectrum analysis values. Refer to Figure 2-86 for an
example limit envelope. Press this submenu key to open the “Limit Envelope
Menu” on page 2-99.
Limit Advanced: Press this submenu key to open the Limit Advanced
submenu key menu. The advanced limit line section offers several useful
functions. In this section, you can create either an absolute limit line (which is
one based upon the frequencies that are entered for each inflection point) or a
relative limit line (which is based upon the delta frequencies between the center
frequency and the inflection points). Both types of limit lines can be saved and
recalled. Press this submenu key to open the “Limit Advanced Menu”
on page 2-101.
Limit Alarm On/Off: Pressing this submenu key toggles the alarm function
ON and OFF for the currently active limit line. When ON, an alarm beep will
occur when a data point exceeds the limit.
Set Default Limit: Pressing this submenu key deletes all limit points for the
currently active limit line and sets the default limit line value, which is a single
limit whose position is 2.5 grid lines from the top of the screen (for the upper
limit line) or 2.5 grid lines from the bottom of the screen (for the lower limit line),
depending upon which limit is active. The inactive limit line is not altered.

Frequency: Press this submenu key to set the frequency of a limit line
inflection point. The frequency of each inflection point in a limit line can be
individually set. When a new point is added, it takes on a value halfway
between two existing points, or it takes on the stop frequency of the current
sweep if no point is higher in frequency than the one being added. See the
Add Point submenu key description for more details. Use the keypad, the left
or right arrow keys, or the rotary knob to change the frequency of an inflection
point. The left or right arrows move the inflection point by 5% of the span.
Amplitude: Press this submenu key to set the amplitude of a limit line
inflection point. The amplitude of each inflection point can also be individually
set. By default, when a new point is added, it takes on the amplitude that is on
the limit line at the frequency where the point was added. Use the keypad
(using the ± key to set a negative value), the up or down arrow keys, or the
rotary knob to move the point to the desired value. The unit of the amplitude
limit is the same as the current vertical amplitude unit. See the Add Point
submenu key description for details. The up or down arrows move the
amplitude by 5% of the screen height.
Add Point: Press this submenu key to add a limit line inflection point. The
precise behavior of this submenu key depends upon which inflection point is
active at the time that the key is pressed. If the active limit point is somewhere
in the middle of a multi-segment limit line, then a new limit point is added that
is halfway between the currently active point and the point immediately to its
right. The amplitude of the inflection point will be such that it falls on the limit
line. For example, if a limit point exists at 2.0 GHz with an amplitude of
–30 dBm, and if the next point is 3.0 GHz with an amplitude of –50 dBm, then
the added point will be at 2.5 GHz with an amplitude of –40 dBm. The
frequency and amplitude values of the new point can be adjusted as needed
with the Frequency and Amplitude submenu keys.
If the last limit point is active (assuming it is not at the right edge of the
display), then the new limit point will be placed at the right edge of the display
at the same amplitude as the point immediately to its left. Points may not be
added beyond the current sweep limits of the instrument.

Add Vertical: In many measurement masks, step changes occur in the
value of the limit line. Press this submenu key to add two inflection points.
The two inflection points share the same frequency and are centered
midpoint between adjacent measured points. The magnitudes of the points
are set by using a visually intuitive algorithm that is based upon the adjacent
inflection points.
You can adjust the magnitudes independently, but the frequencies of the two
points remain linked and are adjusted as a vertical pair. Setting a discrete
frequency, a limit inflection point will keep that exact frequency and place the
limit point appropriately regardless of the frequency span. This is especially
useful for emission mask verification.
Delete Point: Press this submenu key to delete the currently active point.
The active point becomes the point that is immediately to the left of the point
that was deleted.
Next Point Left: Press this submenu key to select the inflection point that is
immediately to the left of the active point, making this newly selected point
active for editing or deletion. With each key press, the active point becomes
that point to the left of the previously active point, until the newly selected
active point becomes the left-most point on the screen.
Next Point Right: Press this submenu key to select the limit point
immediately to the right of the active point, making this newly selected point
active for editing or deletion. With each key press, the active point becomes
that point to the right of the previously active point, until the newly selected
active point becomes the right-most point on the screen.

2.5 grid lines from the top of the screen for the upper limit line or 2.5 grid lines
from the bottom of the screen for the lower limit line.
Move Limit U/D: If the limit line is flat, use this submenu key to move the
limit line to an absolute power point in dBm. If the limit line is not flat, then use
this submenu key to move the limit line up or down by the selected number
of dB. Use the keypad to enter the desired value. The entire line moves by
the amount that is entered. The limit line can also be moved by using the
rotary knob. Turn the rotary knob clockwise to move the line to higher power
levels. The up or down arrows move the limit line by 5% of the screen height.
The left or right arrows move the limit line by 0.2% of the screen height or
0.2 dB when the scale is set to 10 dB/division. The submenu key displays a
zero value after the limit line has been moved.
Move Limit L/R: Pressing this submenu key allows you to adjust the
frequencies of the limit line. All inflection points are moved by the value
entered. The rotary knob can also be used to make this adjustment. Turn the
rotary knob clockwise to move the limit line to higher frequencies. The left or
right arrows move the limit line by 5% of the span while the up or down arrows
move the line by one display pixel. The submenu key displays a zero value
after the limit line has been moved.
Move Limit to Marker 1: Press this submenu key to move the frequency
and amplitude of the center frequency of the limit line to the frequency and
amplitude of Marker 1 (assuming that the Offset from Marker 1 submenu key
is set to 0 dB).
Offset from Marker 1: Press this submenu key to set a limit line offset value
from Marker 1 amplitude. This feature moves the limit line amplitude and
frequency as needed to place the center of the limit line the user-specified
number of dB from the position of Marker 1. Positive values place the limit
line above Marker 1, and negative values place the limit line below Marker 1.

Lower Points (if Lower Limit is selected): Use this submenu key to define
how many inflection points you want for the selected upper or lower limit
envelopes. The value can be between 2 and 41. Note that the upper and
lower limit lines do not need to have the same number of points.
Upper Offset (if Limit is toggled to Upper)
Lower Offset (if Limit is toggled to Lower): This submenu key is used to
define how far away from the measured signal the upper or lower envelope
will be placed. The limits are ± 100 dB. For an upper envelope, usually the
value will be positive in order to place the envelope above the signal. For a
lower envelope, the value will usually be negative in order to place the
envelope below the signal.
Upper Shape Square/Slope (if Limit is toggled to Upper)
Lower Shape Square/Slope (if Limit is toggled to Lower): Press this
submenu key to choose whether the default for the upper or lower envelope
will be with flat tops (Square setting) and reasonably vertical lines to change
level or whether the envelope will have sloped lines (Slope setting) between
adjacent inflection points. When the square envelope type is selected, two
inflection points are used for each horizontal segment. You can toggle
between a square envelope and a sloped envelope by pressing this submenu
key. Figure 2-86 is an example of a Square Limit Envelope.

Introduction
Many wireless networks operate in complex signal environments. Three or four base station
antennas may be located on the same tower and can create interference problems, which can
affect system capacity and coverage.
The Interference Analyzer (option 25) adds five measurement capabilities to the spectrum
analyzer:
• Section 3-4 “Spectrogram” on page 3-2
• Section 3-5 “Signal Strength” on page 3-4
• Section 3-6 “Received Signal Strength Indicator (RSSI)” on page 3-5
• Section 3-7 “Signal ID” on page 3-6
• Section 3-8 “Interference Mapping” on page 3-8
The instrument also has a spectrum mode which displays signals in a traditional spectrum
analyzer view.
Note

setup.
1. For the most effective signal ID display, press the Amplitude main menu key followed
by pressing the Reference Level submenu key. Set the reference level such that the
largest signal to be displayed will be near the top of the graph area of the screen. The
reference value required can be determined by observing the peak of the highest signal
and changing the reference level to place that value near the top of the graph display.
2. Press the Scale submenu key and set the scale value to place the lowest signal near the
bottom of the screen. In general, 4 dB/division or 5 dB/division will be good starting
values.
3. Press the BW main menu key and set Auto RBW and Auto VBW On, or set the applicable
RBW and VBW values by selecting the RBW and VBW submenu keys.
4. Press the Measurements main menu key
5. Press the Signal ID submenu key to activate the measurement. Press Signal ID again to
list the Signal ID menu and to set up the Signal ID test parameters. Set up these
parameters as desired – Scan Type, Scan Freq, Continuous Monitoring, Single Sweep
and Review.
To view the Signal ID data of a single frequency.
1. In the Signal ID menu, press the Scan Type submenu key so that All is selected
(underlined).
2. Press the Single Sweep and Review submenu key. A center frequency and its
accompanying data are highlighted in the table below the graph. In the graph, a dotted
red line marks the center frequency and the band of blue is the associated bandwidth.
Scroll to the desired center frequency in the table and the red dotted line and band of
blue will track accordingly.
3. Press the Scan Type submenu key so that Freq is selected. The center frequency that
was in the table selected is entered as the Scan Freq submenu key frequency
automatically. Now, instead of sweeping across the whole span, the measurement will
only identify the selected frequency and will display its Channel Power as well.

Interference Mapping
Note
Interference Mapping requires GPS Option 31 or the MA2700A which contains a
GPS module.
Interference Mapping assists in quickly identifying the location of an interfering signal using
a directional antenna and a GeoEmbedded map created using Anritsu easyMap Tools
software.
The easyMap Tools program creates single panel maps (.map) for use with Anritsu
instruments. easyMap Tools also creates pan and zoom maps (.azm) compatible with
supported Anritsu instruments. The software imports maps from OpenStreetMap and
Google Maps and creates files with or without GPS information. Anritsu easyMap Tools is
available from the Anritsu website (www.anritsu.com).
Note
For a list of supported instruments, refer to easyMap Tools Help.
With a valid GPS signal, the instrument will identify the current location on the displayed
map with a plus sign. Saved locations are displayed with an orange square. The direction of
the interfering signal can be determined and recorded. With two or more lines, you can see
where the lines intersect and estimate the location of the interferer.

Interference Mapping
Overview
1. Capture a map using Anritsu easyMap Tools. Both non-zoomable (.map) and zoomable
(.azm) map file formats are appropriate.
2. Copy the map file to a USB memory stick and then insert the memory stick into the
Anritsu instrument’s USB Type A port. Anritsu recommends copying the map file to
the instrument’s internal memory.
3. Set the Anritsu instrument to IA mapping and configure the instrument.
4. Load (Recall) the map file.
5. Map the interfering signal.
6. Save the mapping information.
7. View (recall) saved mapping information.
• Saved Maps and KML points can be viewed on the Anritsu instrument. The user
may want to clear any existing points before recalling the map. Refer to “Bearing
Lines Menu” on page 3-67.
• Saved Maps, KML points, Tab Delimited Points, and JPG files can be transferred
and viewed on a PC. Refer to “Mapping Save/Recall Menu” on page 3-68.
The actual mapping process varies based on the direction finding equipment. The process is
described in the following sections:
• “Interference Mapping (Antenna Only)” on page 3-10
• “Interference Mapping (MA2700A and Antenna)” on page 3-14
Note
Some steps that are identical to both processes are repeated for easier reading.
• “Save the Mapping Information” on page 3-19
Measurement updates (including bearing and signal strength) are controlled by
settings of the Anritsu instrument’s Sweep menu (Shift+3) settings and Triggering
Source (Sweep > Triggering > Trigger Source) settings.
Note
The preset parameters (Sweep = Continuous and Trigger Source = Free Run)
allow for continuous measurement updates.
If the instrument display is not updating as expected, confirm these settings.
Additional information is available in “Sweep Menu” on page 3-74 and “Trigger
Source Menu” on page 3-77.

Center Freq: Press the Freq main menu key followed by the Center Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If entering a frequency using the keypad, the
submenu key labels change to GHz, MHz, kHz, and Hz. Press the
appropriate units key. Pressing the Enter key has the same effect as the MHz
submenu key.
Note: When using the up and down arrows, the frequency moves in steps
defined by the value entered using the Freq Step submenu key. When using
the left or right arrow keys, the frequency of the active parameter moves by
10% of the current frequency span. If the instrument is in zero span, the left
and right arrows do nothing. Turning the rotary knob changes the active
frequency parameter in increments of one display point for each click of the
knob. There are 551 display points across the screen.
Start Freq: Press the Freq main menu key followed by the Start Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If a start frequency higher than the current stop
frequency is entered, the stop frequency will be changed to yield a
10 Hz span.
Stop Freq: Press the Freq main menu key followed by the Stop Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If a stop frequency lower than the current start
frequency is entered, the start frequency will be changed to yield a
10 Hz span.
Span: Press the Freq main menu key followed by the Span submenu key
and enter the desired span. The Span menu is used to set the frequency
range over which the instrument will sweep. The span can be set from 10 Hz
to the maximum frequency range the product will support. See the product
specifications for the maximum frequency. Span can also be set to zero span.
The submenu key shows the current value for span in units of GHz, MHz,
kHz, or Hz. When the Span button is pressed, span becomes the active
parameter and may be changed. Use the keypad, the directional arrow keys,
or the rotary knob to increase or decrease the span frequency. If the span is
changed using the arrow keys, the span changes in 1-2-5 steps for each key
press. See “Span Menu” on page 3-36.

Span: This submenu key shows the current value for span in units
of GHz, MHz, kHz, or Hz. When the Span button is pressed, span becomes
the active parameter and may be changed. Use the keypad, the directional
arrow keys, or the rotary knob to increase or decrease the span frequency.
If the span is changed by using the up and down arrow keys, the span
changes by the value of the Frequency Step entered in the “Freq (Frequency)
Menu” on page 3-31.
Span Up 1-2-5: This is a convenient way to quickly arrive at a wider span
value. The first time the submenu key is pressed, the span value increases to
the nearest even value that starts with 1, 2, or 5. For example if the span is
1.8 MHz, pressing the submenu key for the first time changes the span to
2.0 MHz, the next press takes the value to 5.0 MHz and so on.
Span Down 1-2-5: This is a convenient way to narrow the frequency span.
The first time the submenu key is pressed, the span value decreases to the
nearest even value that starts with 1, 2, or 5. For example if the span is
1.8 MHz, pressing the submenu key for the first time changes the span to
1.0 MHz, the next press takes the value to 500 kHz, then 200 kHz and so on.
Full Span: Pressing this button sets the span to cover the entire frequency
range of the instrument.
Zero Span: This submenu key sets zero span. In this mode the display
shows amplitude changes at a single frequency. This function is frequently
used to allow the easy monitoring of power variations over time. For example,
if information about the amplitude of an 802.11a access point signal is
needed, the access point frequency would be set as the center frequency,
resolution bandwidth would be set to a value wide enough to encompass as
much of the signal as possible and the tester would walk around the access
point usable area while the instrument records the amplitude using slow
sweep.
Zero Span (Option 89): If Option 89 is installed on your instrument, press
the Zero Span key again (after the circle is red) to access the “Zero Span
IF BW Menu (Option 89)” on page 3-37.
Last Span: This submenu key returns the span to the most recent span
value immediately before a change was made.
Back: Returns to the previous menu.

Auto Atten On/Off: Input attenuation can be either tied to the reference
level (On) or manually selected (Off). When input attenuation is tied to the
reference level, attenuation is increased as higher reference levels are
selected to make sure the instrument input circuits are not saturated by large
signals that are likely to be present when high reference levels are required.
Atten Lvl: Press this submenu key and use the numeric keypad, the rotary
knob, or the arrow keys to change the attenuation value.
RL Offset xx dB Ext Gain/Loss: RL Offset compensates for the presence
of external input attenuation or gain. Enter a positive value to compensate for
gain or loss, then press the appropriate submenu key (dB External Gain or dB
External Loss). The new RL Offset value will be displayed on the button.
Pre Amp On/Off: This submenu key turns the low-noise front-end
preamplifier on or off. To ensure accurate measurement results, the largest
signal into the instrument input when the preamplifier is turned on should be
less than –40 dBm.
Units & Detection: Press this submenu key to open the “Units & Detection

on page 3-22. Press Back to return to the Amplitude menu.
Detection: Several detection methods tailor the function of the instrument
to meet specific measurement requirements. There are often more
measurement points across the screen than display points. The various
detection methods are different ways of dealing with how measurement
points will be shown at each display point. The Detection submenu is
illustrated on the lower left.
Back
Detection
Peak
RMS/Avg
Negative
Sample
Quasi-peak
Peak: This method causes the largest measurement point to be
shown for each display point, assuring that a narrow peak is not
missed.
RMS/Avg: In the Preset case, when the VBW/Average Type is set to
Linear, this method detects the average power of measurement points
that go into the display point. When VBW/Average Type is set to Log,
the traditional average of log(power), such as dBm, is displayed for
the detector, as well as for VBW and trace average.
Negative: This method causes the smallest measurement point to be
shown for each display point. It is especially useful in zero span, to
see if the signal amplitude drops briefly. The method is also useful
when looking at modulated signals, to see if some frequencies are not
being used.
Sample: This is the fastest detection method because for each
display point, only one frequency point is measured. Use this method
when speed is of paramount importance and the possibility of missing
a narrow peak is not important.
Quasi-peak: When this selection is made, resolution bandwidths and
video bandwidths of 200 Hz, 9 kHz and 120 kHz are available. This
detection method is designed to meet CISPR requirements.

VBW: The current video bandwidth value is displayed in this submenu key.
The key displays the Zero Span VBW if Zero Span is selected. The VBW can
be changed using the keypad, the arrow keys, or the rotary knob. Bandwidth
values increment in a 1 to 3 sequence, from 1 Hz to 3 Hz to 10 Hz, or from
10 Hz to 30 Hz to 100 Hz, for example. Refer to your instrument Technical
Data Sheet for the video bandwidth range.
Auto VBW On/Off: When Auto VBW is On, the instrument selects the video
bandwidth based on the resolution bandwidth. The ratio of video bandwidth to
resolution bandwidth can be set using the RBW/VBW submenu key.
VBW/Average Type: Toggles between Linear averaging (arithmetic mean)
and Logarithmic averaging (geometric mean).
RBW/VBW: This submenu key displays the ratio between resolution
bandwidth and video bandwidth. To change the ratio, press this submenu key
and use the keypad, the arrow keys, or the rotary knob to select a new ratio.
The default ratio is 3. When the quasi-peak detector is selected the
RBW/VBW ratio is changed to 1.
Span/RBW: This submenu key displays the ratio between the span width
and the resolution bandwidth. The default value is 100, meaning that the span
width is approximately 100 times the resolution bandwidth. The value is
approximate because resolution bandwidth filters come in discrete steps
while span width can be set to any value up to the limit of the instrument.
To change the ratio, press this submenu key and use the keypad, the arrow
keys, or the rotary knob to select a new ratio.

binary data. The beginning of the file contains all of the capture-related
parameters such as center frequency, bandwidth, and capture rate as well as
any contextual information about the file, such as time, date, and GPS
location (if available). At the bottom of the file, in between the <Data> tags,
is the raw I and Q data in binary form. I and Q data points are each 3 bytes
long and stored in 24-bit twos complement in an alternating fashion
(in other words, I0, Q0, I1, Q1…).

keypad, the submenu key labels change to GHz, MHz, kHz, and Hz. Press
the appropriate units key. Pressing the Enter key has the same effect as
the MHz submenu key. With zero offset, this key is labeled Center Freq. With
an offset other than zero, the key is labeled Offset Center Freq, as illustrated
on the left, below the full menu. Refer to “Frequency Menu with Offset
Function” on page 3-33.
Span: Lets you set the frequency span to be displayed on the instrument.
This submenu key shows the current value for span in units
of GHz, MHz, kHz, or Hz. When the Span button is pressed, span becomes
the active parameter and may be changed. Use the keypad, the directional
arrow keys, or the rotary knob to increase or decrease the span frequency. If
the span is changed using the arrow keys, the span changes in a 1-2-5
sequence for each key press.
Reference Level: The reference level is the top graticule line on the display,
and can be set from +30 dBm to –150 dBm. A value may be entered from the
keypad, use the ± key for a minus sign. After entering the value press
the dBm submenu key or the Enter key. The up or down arrow keys change
the reference level in 10 dB steps, and the left or right arrow keys change the
value by 1 dB. The rotary knob changes the value by 0.1 dB per click. The
reference level value may be modified by the reference level offset value to
compensate for an external attenuator or amplifier.
Scale: The y-axis scale can be set in 1 dB steps from 1 dB per division to
15 dB per division. The value can be changed using the keypad, the rotary
knob or the arrow keys.
Auto Atten: Input attenuation can be either tied to the reference level (On)
or manually selected (Off). When input attenuation is tied to the reference
level, attenuation is increased as higher reference levels are selected to
make sure the instrument input circuits are not saturated by large signals that
are likely to be present when high reference levels are required.
Atten Level: Press this submenu key and use the keypad, the rotary knob or
the arrow keys to change the attenuation value.

A negative delay displays the trigger position on screen, while a positive
value places the trigger point off the screen to the left.
Level: Sets a trigger level to initiate a measurement when Video or IF
Power is selected in the “Trigger Source Menu” on page 3-77. Press this
key, then use the rotary knob, arrow keys, or numeric keypad to enter the
trigger power level. The value ranges from –150 dBm to +30 dBm.
Slope: Sets the trigger slope to rising or falling.
Hysteresis: When used, value unit is in dB. Hysteresis can be used with
Level and Slope when setting a measurement trigger. Hysteresis is used
to prevent undesired triggering when the signal is hovering near the
trigger value. For example, the Level is set to 10 dBm, the Slope is set to
Rising, and Hysteresis is 1 dB. The first trigger occurs when the signal at
least reaches the 10 dBm level. To trigger again, the signal must drop
below 9 dBm before returning to 10 dBm. For another example, with Level
set to 10 dBm and slope set to Falling, and Hysteresis set to 1 dB, the
opposite must occur to activate a trigger. The signal amplitude falls and a
trigger occurs when the signal reaches the 10 dBm level. The signal must
then reach at least 11 dBm before falling to 10 dBm and initiating a trigger.
Holdoff: Delays the next trigger to the time set regardless of triggers
occurring within the set time.
Force Trigger Once: Forces a sweep regardless of meeting any trigger
criteria.

Limit Menu
Key Sequence: Shift > Limit (6) key
Two types of limit lines can be specified, lower limit lines and upper limit lines. Limit lines
can be used for visual reference only, or for pass/fail criteria using the limit alarm
(Figure 3-77). Limit alarm failures are reported whenever a signal is above the upper limit
line or below the lower limit line. By using save-on-event, a signal that causes a limit alarm
can be automatically saved. Refer to your User Guide for details.
Each limit line can consist of a single segment, or as many as 40 segments. These limit
segments are retained regardless of the current frequency span of the instrument, which
allows the configuring of specific limit envelopes at various frequencies of interest without
having to re-configure them each time the frequency is changed.
This menu is active only when making Spectrum measurements. The key
sequence is not operational when Spectogram, Signal Strength, RSSI, Signal ID,
or Interference Mapping measurements are active.

Limit Envelope: A limit envelope is very useful when you want to easily detect
new signals in the presence of other preexisting signals. Use the limit envelope
function to automatically create upper or lower limit lines that are based upon
the on-screen measured spectrum analysis values. Refer to Figure 3-82 for an
example limit envelope. Press this submenu key to open the “Limit Envelope
Menu” on page 3-87.
Limit Advanced: Press this submenu key to open the Limit Advanced
submenu key menu. The advanced limit line section offers several useful
functions. In this section, you can create either an absolute limit line (which is
one based upon the frequencies that are entered for each inflection point) or a
relative limit line (which is based upon the delta frequencies between the center
frequency and the inflection points). Both types of limit lines can be saved and
recalled. Press this submenu key to open the “Limit Advanced Menu”
on page 3-89.
Limit Alarm On/Off: Pressing this submenu key toggles the alarm function
ON and OFF for the currently active limit line. When ON, an alarm beep will
occur when a data point exceeds the limit.
Set Default Limit: Pressing this submenu key deletes all limit points for the
currently active limit line and sets the default limit line value, which is a single limit
whose position is 2.5 grid lines from the top of the screen (for the upper limit line)
or 2.5 grid lines from the bottom of the screen (for the lower limit line), depending
upon which limit is active. The inactive limit line is not altered.

Frequency: Press this submenu key to set the frequency of a limit line
inflection point. The frequency of each inflection point in a limit line can be
individually set. When a new point is added, it takes on a value halfway
between two existing points, or it takes on the stop frequency of the current
sweep if no point is higher in frequency than the one being added. See the
Add Point submenu key description for more details. Use the keypad, the left
or right arrow keys, or the rotary knob to change the frequency of an inflection
point. The left or right arrows move the inflection point by 5% of the span.
Amplitude: Press this submenu key to set the amplitude of a limit line
inflection point. The amplitude of each inflection point can also be individually
set. By default, when a new point is added, it takes on the amplitude that is on
the limit line at the frequency where the point was added. Use the keypad
(using the ± key to set a negative value), the up or down arrow keys, or the
rotary knob to move the point to the desired value. The unit of the amplitude
limit is the same as the current vertical amplitude unit. See the Add Point
submenu key description for details. The up or down arrows move the
amplitude by 5% of the screen height.
Add Point: Press this submenu key to add a limit line inflection point. The
precise behavior of this submenu key depends upon which inflection point is
active at the time that the key is pressed. If the active limit point is somewhere
in the middle of a multi-segment limit line, then a new limit point is added that
is halfway between the currently active point and the point immediately to its
right. The amplitude of the inflection point will be such that it falls on the limit
line. For example, if a limit point exists at 2.0 GHz with an amplitude of
–30 dBm, and if the next point is 3.0 GHz with an amplitude of –50 dBm, then
the added point will be at 2.5 GHz with an amplitude of –40 dBm. The
frequency and amplitude values of the new point can be adjusted as needed
with the Frequency and Amplitude submenu keys.
If the last limit point is active (assuming it is not at the right edge of the
display), then the new limit point will be placed at the right edge of the display
at the same amplitude as the point immediately to its left. Points may not be
added beyond the current sweep limits of the instrument.

Add Vertical: In many measurement masks, step changes occur in the
value of the limit line. Press this submenu key to add two inflection points.
The two inflection points share the same frequency and are centered
midpoint between adjacent measured points. The magnitudes of the points
are set by using a visually intuitive algorithm that is based upon the adjacent
inflection points.
You can adjust the magnitudes independently, but the frequencies of the two
points remain linked and are adjusted as a vertical pair. Setting a discrete
frequency, a limit inflection point will keep that exact frequency and place the
limit point appropriately regardless of the frequency span. This is especially
useful for emission mask verification.
Delete Point: Press this submenu key to delete the currently active point.
The active point becomes the point that is immediately to the left of the point
that was deleted.
Next Point Left: Press this submenu key to select the inflection point that is
immediately to the left of the active point, making this newly selected point
active for editing or deletion. With each key press, the active point becomes
that point to the left of the previously active point, until the newly selected
active point becomes the left-most point on the screen.
Next Point Right: Press this submenu key to select the limit point
immediately to the right of the active point, making this newly selected point
active for editing or deletion. With each key press, the active point becomes

The span of the existing limit line is not changed by doing this. Use this
submenu key as an easy way to get an existing limit line on screen. If no limit
line is turned on, then a new, flat default limit line is turned on and is located
2.5 grid lines from the top of the screen for the upper limit line or 2.5 grid lines
from the bottom of the screen for the lower limit line.
Move Limit ## dB: If the limit line is flat, then use this submenu key to move
the limit line to an absolute power point in dBm. If the limit line is not flat, then
use this submenu key to move the limit line up or down by the selected
number of dB. Use the keyboard to enter the desired value. The entire line
moves by the amount that is entered. The limit line can also be moved by
using the rotary knob. Turn the rotary knob clockwise to move the line to
higher power levels. The up and down arrows move the limit line by 5% of the
screen height. The left and right arrows move the limit line by 0.2% of the
screen height or 0.2 dB when the scale is set to 10 dB/division.
Move Limit ## Hz: Pressing this submenu key allows you to adjust the
frequencies of the limit line. All inflection points are moved by the value
entered. The rotary knob can also be used to make this adjustment. Turn the
rotary knob clockwise to move the limit line to higher frequencies. The left or
right arrows move the limit line by 5% of the span while the up or down arrows
move the line by one display pixel.
Move Limit to Marker 1: Press this submenu key to move the frequency
and amplitude of the center frequency of the limit line to the frequency and
amplitude of Marker 1 (assuming that the Offset from Marker 1 submenu key
is set to 0 dB).
Offset from Marker 1 ## dB: Press this submenu key to set a limit line
offset value from Marker 1 amplitude. This feature moves the limit line
amplitude and frequency as needed to place the center of the limit line the
user-specified number of dB from the position of Marker 1. Positive values
place the limit line above Marker 1, and negative values place the limit line
below Marker 1.

Pressing this submenu key makes those amplitude adjustments without
frequency adjustments.
Upper Points (if Upper Limit is selected)
Lower Points (if Lower Limit is selected): Use this submenu key to define
how many inflection points you want for the selected upper or lower limit
envelopes. The value can be between 2 and 41. Note that the upper and
lower limit lines do not need to have the same number of points.
Upper Offset (if Limit is toggled to Upper)
Lower Offset (if Limit is toggled to Lower): This submenu key is used to
define how far away from the measured signal the upper or lower envelope
will be placed. The limits are ±100 dB. For an upper envelope, usually the
value will be positive in order to place the envelope above the signal. For a
lower envelope, the value will usually be negative in order to place the
envelope below the signal.
Upper Shape (if Limit is toggled to Upper)
Lower Shape (if Limit is toggled to Lower): Press this submenu key to
choose whether the default for the upper or lower envelope will be with flat
tops (Square setting) and reasonably vertical lines to change level or whether
the envelope will have sloped lines (Slope setting) between adjacent
inflection points. When the square envelope type is selected, two inflection
points are used for each horizontal segment. You can toggle between a
square envelope and a sloped envelope by pressing this submenu key.

Introduction
This chapter presents Channel Scanner information and procedures. The Channel Scanner
option (Option 27) measures the signal power of multiple transmitted signals. The power can
be displayed as either a bar graph or a text display showing the channel power of selected
channels for a given air interface standard, or the manually entered channels. Up to
20 channels can be measured.
The operating frequency range for Channel Scanner mode can either be set manually, or the
desired air interface standard can be selected from the Signal Standard and channel list in
the instrument. When the channels are selected from the Signal Standard list, all frequency
related parameters for the standard are automatically set to the appropriate values. The
frequency and bandwidth settings can be manually entered using the Scan Frequencies
selection if none of the available air interface standards meet the measurement need.
A custom channel list can also be created to allow up to 20 independent channels to be
defined.
With the use of Master Software Tools, Script Master extends the test capabilities of channel
scanner testing of the instrument. Features include the use of a Script Master Test Setup File
to set test parameters, extending the number of channel scans to 1200, repetitive testing, and
time testing.
Note

Custom Setup Example
This example explains how to monitor several signals, plus a potential intermodulation
product, to see if there is a correlation between the nearby signals and an intermittent
interference problem.
The signals on or near the rooftop are:
• An FM broadcast station at 106.5 MHz
• A paging transmitter at 157.86 MHz
• Three cellular sites:
• US CDMA PCS channel 50 (1932.5 MHz)
• LTE Band 13 DL channel 5230 (751 MHz)
• GSM 1800 channel 512 (1805.2 MHz)
• A Ham repeater at 147.36 MHz
• A Ham repeater at 446.5 MHz
• A land mobile repeater at 451.7875 MHz
• A public safety repeater at 485.5625 MHz
• In addition, the site is near the flight path of an airport. The approach frequency is
121.4 MHz.
Set up a measurement channel for each of the signals to be observed plus extra channels for
any intermodulation products to be observed.

Script Master Measurement Setup
The Script Measurement function (Scanner | Scan Scriptmaster) allows the user to increase
the number of channels to scan from 20 channels to 1,200 channels. Channel scanning is done
in groups of 20. So if the maximum number of channels were set, then there would be 60 sets
of 20 channels.
The Channel Scanner Script Master allows the user to automatically repeat scanning of all
channels multiple times. You may choose to repeat the scan for a specified number of cycles,
or choose a time duration until which the scan is repeated or ended. Please refer to
Script Master Editor in Master Software Tools for creating and uploading Script Files to the
instrument.
Press the Repeat Scan Type submenu key to set either the number of scans or period of time
as the mode of testing. If # Scans is selected, use the # of Repeat submenu key to set the
number of repetitions for testing the full list of channels in the Script Master Test file. The
maximum number of repetitions is 1000. If Time is selected, use the Scan Duration submenu
key to setup a test period for testing the channels in the Script Master Test File.
If testing the number of channels in the Script Master Test File is shorter than the Scan
Duration, testing those channels will repeat. If testing the number of channels in the Script
Master Test File is longer than the Scan Duration, scanning ends and the rest of the channels
are not tested. Units for Scan Duration is days, hours, minutes, and seconds, with a
maximum scan time of three days and a minimum scan time of ten minutes.
The sets of channels in the Script Master Test File can also be tested repeatedly. Use the # of
Repeats (Set) submenu key to set this parameter. For example, if 5 were entered, then each
set of 20 channels, would be tested five times before the next set of channels are tested.
The # of Repeats (Set) feature can be used in combination with # of Repeats (List) feature.
For example, the Script Master Test File contains 100 channels, that is 5 sets of 20 channels.
# of Repeats (Set) is set to 3 and # of Repeats (List) is set to 5. Pressing the Start/Restart Test
button starts test on the first 20 channels for 3 iterations, then testing moves to the 2nd set of
channels for 3 iterations and continues on till the 5th set is tested for 3 iterations. Then the
list of 100 channels are tested again with each set of channels being tested 3 times. Testing is
ended when five cycles of testing on 100 channels completed.

Chapter 5 — CW Signal Generator
(Option 28)
Note
5-1
Not all instrument models offer every option. Refer to the Technical Data Sheet of
your instrument for available options.
Introduction
This chapter presents information and procedures used to make measurements using the
optional CW Signal Generator mode (Option 28).
The CW Signal Generator provides a continuous wave (CW) signal from the VNA RF Out port
of the instrument. The CW signal is primarily used for testing the sensitivity of receivers. To
test receiver sensitivity, connect the signal directly to the receiver that is being measured,
and then reduce the output amplitude until the receiver drops the signal.
The external splitter feeds the signal into the RF input of the instrument. The display shows
the output power and frequency. The amplitude is set by using an external step attenuator.
The external splitter and attenuator are purchased separately. They are available as CW
Signal Generator Kit. The “fixed” CW signal levels vary as a function of the frequency.

Introduction
Coverage Mapping Option 431 allows users to map RSSI and ACPR measurements. The
Anritsu easyMap Tools program creates special maps compatible with Anritsu handheld
spectrum analyzers. The software creates files with or without GPS information. The files
will have a .map extension. easyMap Tools is available from the Anritsu website
(www.anritsu.com).
The Coverage Mapping option is suitable for both indoor and outdoor mapping.
Note

Coverage Mapping
Note
Outdoor coverage mapping requires Option 31, GPS.
Coverage Mapping is possible both outdoors (GPS signal required) and indoors (no GPS
signal). For more accurate position data for indoor measurements, use a stylus such as the
Anritsu 2000-1691-R.
• Outdoor Mapping: The instrument logs data automatically based on either time or
distance interval. If there is no map available when making the measurements, it is
still possible to save all the data to a KML file and then combine the data with a map.
You may also recall a map after taking the data without having to save and recall it.
• Indoor Mapping: Using a start-walk-stop approach, the instrument provides
in-building coverage mapping by overlaying data directly onto the downloaded map
(which may be a drawing of a building). Data is captured when you tap the touch
screen. The instrument places points linearly between taps if Time interval is used for
capturing data and there is more than one measurement. When the Repeat Type is
Distance, new measurements are placed at the next tap point.
Outdoor Coverage
With a valid GPS signal, the instrument identifies the current location on the displayed
GeoEmbedded map with a plus sign. Previously saved locations are displayed as squares.
Using GPS, latitude, longitude, and altitude data is automatically saved for each location.

Anritsu easyMap Tools allows you to capture maps of any location and create Anritsu Map
Files. These maps are used for Coverage Mapping and Interference Mapping (Chapter 3).
There are two Anritsu Map File formats:
• legacy .map map files
• .azm map files, which are displayed in full zoom-out view (Coverage Mapping
pan-and-zoom is currently supported on the LMR Master S412E only)
Download easyMap Tools from the Anritsu website (www.anritsu.com). Additional
information about easyMap Tools is available in the software Help.
Outdoor Map
Type an address in easyMap Tools and capture the map with GPS data.
Indoor Map
In easyMap Tools, open a bitmapped image (JPEG, GIF, TIFF, or PNG) of the floor plan for
indoor mapping. You can also use a downloaded map and make it an indoor map. This method
works well if you can get a good aerial view of a building.
The image size should be close to 666 pixels x 420 pixels (approximately 1.6:1 ratio).

Map the Signal Strength
Coverage Mapping supports RSSI measurement or ACPR measurement during mapping.
The default settings for coverage mapping set the internal input attenuator to 0 dB
(off) with the preamp on and a bandwidth of 1 MHz. These parameters can be
adjusted depending on the strength of the signal being measured. The bandwidth
is 10 kHz for RSSI measurements. For ACPR, it is based on ACPR settings
(channel width and spacing) and the resultant span, as well as if Auto RBW is set.
Note
Overdriving the input of the spectrum analyzer can result in ADC Overdrive or
Saturation errors. Refer to “Indications of Excessive Signal Level” on page 2-10. If
necessary, make adjustments using the Amplitude menu and BW menu.
Once data collection begins, parameters such as amplitude, bandwidth or
measurement setup cannot be changed.

Introduction
This chapter presents information and procedures that are used to make measurements
when using the optional AM/FM/PM Analyzer mode (Option 509).
The AM/FM/PM Analyzer provides display and analysis of the key characteristics of analog
AM, FM, and PM modulated signals. The AM/FM/PM Analyzer provides the following
displays:
1. RF Spectrum shows the RF Spectrum graph, which is similar to Spectrum Analyzer
mode with carrier power, carrier frequency, and occupied bandwidth measurements.
To get to this view, select the Measurements menu and then press RF Spectrum. To
change the occupied bandwidth measurement, press RF Spectrum again and make
changes as desired.
2. Audio Spectrum shows the demodulated audio spectrum along the with the following
measurements: Rate, RMS, Pk-Pk/2, SINAD, THD, and Distortion/Total. To change
X-axis values to 2 kHz, 5 kHz, 10 kHz, 20 kHz, 70 kHz, or 140 kHz, press
Audio Spectrum again and change Span. When analyzing FM and PM, the reference
Y-axis value is also scalable.
3. Audio Waveform displays the time-domain demodulated waveform along with Rate,
RMS, Pk-Pk/2, SINAD, THD, and Distortion/Total measurements. The X-axis value
can be changed by pressing Audio Waveform and changing the Sweep Time. When
analyzing FM and PM, the reference Y-axis value is also scalable.
4. Summary displays all of the above mentioned measurements from RF Spectrum as
well as the demodulated signal.
5. AM/FM/PM Coverage Mapping (Option 431 and Option 31 also required) allows
users to map SINAD and Carrier Power measurements in a given geographical area.
Note that Option 31 is not required for indoor mapping.

Chapter 8 — Bias Tee (Option 10)
Note
8-1
Not all instrument models offer every option. Please refer to your instrument
Technical Data Sheet for available options.
Introduction
Option 10 provides a bias tee that is installed inside the instrument. The bias arm is
connected to a 12 VDC to 32 VDC power source that can be turned on as needed to place the
voltage on the center conductor of the instrument’s RF In port. This supply of bias implies it is
mostly useful when conducting two-port transmission measurements. This voltage can be
used to provide power to block down-converters in satellite receivers and can also be used to
power some tower-mounted amplifiers.
The bias can be turned on only when the instrument is in transmission measurement,
return loss, cable loss, VSWR, DTF, Spectrum Analyzer, Channel Scanner, and Interference
Analyzer mode. When bias is turned on, the bias voltage and current are displayed in the
lower left corner of the display. The 12 VDC to 32 VDC power supply is designed to
continuously deliver a maximum of 6 Watts.
Refer to Figure 8-1 on page 8-2 for a sample TMA connection.

Sheet of your instrument for available options.
Note
9-1
Introduction
Option 444 adds the EMF Measurement menu to the Spectrum Analyzer measurement mode.
It must be used in conjunction with the Anritsu isotropic antenna, at a frequency range that
is within specification of the instrument and antenna used. Refer to the isotropic antenna and
spectrum analyzer technical data sheets.
9-2
Connecting the Antenna
1. Connect the antenna RF connector to the Analyzer/RF In port on the instrument. See
Figure 9-1. The antenna connector must be finger tight.
2. Connect the antenna USB connector to one of the USB Type A ports on the instrument.

where you can set up EMF parameters and start the measurement. EMF
must be turned On.
Limits
On
On/Off: This is the main EMF Measurement On/Off button. Press this key to
switch EMF On and Off. The start and stop frequencies must be within the
range of the spectrum analyzer and isotropic antenna used, and the antenna
must be connected. The detection type is automatically changed to RMS/Avg
when EMF is On. It is restored to the previous detection setting when EMF is
Off.
Limits: This is a shortcut to the standard spectrum analyzer Limits menu
(Shift > Limit (6)). For EMF measurements, only the upper limit line is used
for testing the pass/fail condition. Multi-segment limit lines can also be
created.
ICNIRP Limit On/Off: Turning this On creates a limit line consistent with the
guidelines of the International Commission on Non-Ionizing Radiation
Protection. Trace C contains the averaged isotropic result and is tested
against this limit line, and then the Pass/Fail status is updated.
Units: The unit choices are dBm/m2, dBV/m, dBmV/m, dBuV/m, V/m, W/m2,
dBW/m2, A/m, dBA/m, W/cm2. dBm/m2 is the default.

Measurement On/Off: Starts the EMF Measurement. The Dwell Time,
Measurement Time, and other related parameters must be set before starting
the measurement. This button is useful for stopping or restarting
measurements when settings need to be changed. When the measurement is
in progress, access to other menus and key presses are blocked. The
Measurement On/Off key is then the only key that can be accessed.
Measurement Time: Sets the duration of each EMF measurement from one
minute up to 30 minutes. The default is 6 min. For example, if Axis Dwell Time
is set to 1 s and Measurement Time is 1 min, you will get one isotropic result
after 3 s and approximately 20 at the end of the one-minute measurement.
The Current row in the summary table at the bottom of the screen displays a
running average, max and min of these isotropic results every 3 s. The
displayed values are computed from all measurements completed thus far
within the measurement time. At the end of the measurement time, the
Current row is cleared and the Total row is updated with the max, min, and
running average of all isotropic results (20 in this example).
Number of Measurements: Sets the number of EMF measurements to
complete from 1 up to 10,000. The EMF test is fully executed when the
specified number of measurements have completed.
Auto Logging On/Off: Auto Logging is On by default. This must be selected
prior to starting the measurements for the results to be logged. The average,
max, and min values of each isotropic set of three axes, the isotropic trace
data, and the computed total average, max, and min values are saved in a tab
delimited text file in internal memory.
The location of this log file is a new folder named with the current time stamp
followed by _1, and created in “/Internal Memory/EMF/”. The folder can hold
100 files. Each file holds five measurements. The 101st file and the files
created thereafter are stored in a new folder with the same time stamp as the
first, followed by _2 (then _3, and so on). Each file has its own time stamp.

After completing the data collection for the three axes, the Isotropic Result is calculated and
displayed. In addition to the three traces displayed on the user interface (Axis Sweep Data,
Current Isotropic Result, and Average Isotropic Result/Measurement), the max, min, and
average values of the Isotropic Result traces are also computed and displayed in the table
below the graph region. See Figure 9-5. The average value is computed as:
sum of the 551 trace point amplitudes / 551
The Current row displays values computed for all measurements completed thus far, as
indicated by Measurement Number (2/5, for example) at the bottom of the table. At the end of
the specified measurement time, the current max, min, and average values are copied to the
Total row. The Current row is then cleared for the next measurement. The Isotropic Results
are updated until the set number of measurements have completed or you stop the
measurements by pressing the Measurement On/Off key.

Pass/Fail
The limit check is done at the end of each measurement and determines the Pass/Fail status
of the tests. The limit line, if selected, is applied against the Iso Avg trace. To show or hide the
Current Test Status and Final Test Result, press the Limits submenu key in the EMF menu
(see Figure 9-2 on page 9-2), then press the On/Off key.
At the end of the specified measurement time and if the trace exceeds the selected limit, a
FAIL is recorded and the Current Test Status in the summary table is updated to FAIL. In that
case, the Final Test Result is immediately displayed as a FAIL. If the Average Isotropic Result
does not cross the limit line, then the Current Test Status is updated to PASS and stays this
way for a few sweeps. The Current Test Status is then updated to “--”. See Figure 9-5
on page 9-5. If all of the measurements pass, the Final Test Result is updated to PASS. See
Figure 9-6.
If Auto Logging is set to On prior to starting the measurements, Pass/Fail results are saved in
a log file with the Isotropic Results. Refer to “EMF Auto Menu” on page 9-3.
