1-2Instrument Description
The MT8220T BTS Master is an integrated multi-functional base station test tool that
eliminates the need to carry and to learn to use multiple test sets. The measurement
capabilities include: spectrum analyzer smart measurements, precision return loss, VSWR,
cable loss, distance-to-fault, two port gain/loss, one-port and two-port magnitude and phase,
interference analysis, spectrogram, and power meter.
RF, advanced demodulation, and over-the-air (OTA) measurements can be applied to
GSM/GPRS/EDGE, W-CDMA/HSPA+, TD-SCDMA/HSPA+, LTE FDD/TDD, CDMA/EV-DO,
and WiMAX Fixed/Mobile signals.
Additional capabilities include a Vector Signal Generator (VSG), GPS location information,
and enhanced external frequency reference oscillator accuracy.
The MT8220T model has cable and antenna analysis (400 MHz to 6.0 GHz), spectrum
analysis (150 kHz to 7.1 GHz), and an internal power meter (10 MHz to 7.1 GHz). The cable
and antenna analysis is performed by a Vector Network Analyzer that is designed to make
accurate vector-corrected 1-port and 1-path, 2-port magnitude and phase measurements from
400MHz to 6GHz.

General Information1-2 Instrument Description
The MT8220T is also a synthesizer-based spectrum analyzer that provides quick and
accurate measurement results. Measurements can be easily made by using the main
instrument functions: frequency, span, amplitude, and bandwidth. Dedicated keys for
one-button measurements of field strength, channel power, occupied bandwidth, Adjacent
Channel Power Ratio (ACPR), and Carrier to Interference Ratio (C/I) make the handheld
MT8220T the ideal choice for the field. A familiar calculator-type keypad allows for fast data
entry.
In transmitter analyzer mode, the MT8220T displays 6 markers and the marker table in
Code Domain Power and Codogram displays. In Spectrum Analyzer mode, a full range of
marker capabilities (such as peak, center, and delta functions) are provided for faster, more
comprehensive analysis of displayed signals. Upper and lower multi-segmented limit lines
are available to create quick, simple pass/fail measurements. A menu option provides for an
audible alert when a limit value is exceeded.
Time and date stamping of measurement data is automatic. The internal memory provides
for storage and recall of traces and measurement setups. The bright daylight-viewable,
high-resolution, color liquid crystal display (LCD) provides easy viewing in a variety of
lighting conditions. The MT8220T is capable of approximately 2.5 hours of continuous
operation from a fully charged battery and can be operated from a 12 VDC source, which also
simultaneously charges the battery.
Several PC-based software programs are available free-of-charge from Anritsu. Refer to
Chapter 7 for a brief overview.
• Anritsu Master Software Tools (MST) provides a convenient means for storing
measurement data. Master Software Tools can also convert measurements from the
display into several graphic formats. Master Software Tools supports all of the options
that are provided with the instrument.
• Line Sweep Tools (LST) can be used with Cable & Antenna measurements to create
reports, view and organize data, analyze historical data, edit markers and limit lines,
rename traces and trace analysis.
• easyMap Tools is used to create maps for coverage and interference mappings.
Additional information for specific software programs is available under the software’s
Help menu.
Measurements may be stored in internal memory, on a USB flash drive, or a
FAT32-formatted external disk. Stored measurements can be downloaded to a PC by using
the included USB and Ethernet cables. After being stored, the graphic trace can then be
displayed, scaled, or enhanced with markers and limit lines. Historical graphs can be overlaid
with current data by using the PC mouse in a drag-and-drop fashion. The underlying data
can be extracted and used in spreadsheets or for other analytical tasks.

The MT8220T loads factory calibration data during start-up, eliminating the need for daily
calibration checks. In W-CDMA mode, an additional automatic calibration is performed as
the internal temperature of the MT8220T changes (to ensure the best possible measurement
results). The Cable and Antenna Analyzer mode requires calibration standards for OPEN,
SHORT, and LOAD (OSL), which are sold separately.
Although the MT8220T does not require daily field calibration, Anritsu recommends an
annual calibration and performance verification by local Anritsu service centers. Contact
information for Anritsu Service Centers is available at http://www.anritsu.com/contact-us.

General Information1-4 Instrument Care and Preventive Maintenance
1-4Instrument Care and Preventive Maintenance
BTS Master care and preventive maintenance consist of cleaning the unit and inspecting and
cleaning the RF connectors on the instrument and all accessories. Clean the BTS Master with
a soft, lint-free cloth dampened with water or water and a mild cleaning solution.
Caution To avoid damaging the display or case, do not use solvents or abrasive cleaners.
Connector Care
Clean the RF connectors and center pins with a cotton swab dampened with denatured
alcohol. Visually inspect the connectors. The fingers of N(f) connectors and the pins of N(m)
connectors should be unbroken and uniform in appearance. If you are unsure whether the
connectors are undamaged, gauge the connectors to confirm that the dimensions are correct.
Visually inspect the test port cables. Test port cables should be uniform in appearance, not
stretched, kinked, dented, or broken.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
Type-N connectors. The recommended torque is 12 lbf·in to 15 lbf· in (1.36 N ·m to 1.70 N·m).
Inadequate torque settings can affect measurement accuracy. Over-tightening connectors can
damage the cable, the connector, the instrument, or all of these items.
Visually inspect connectors for general wear, cleanliness, and for damage such as bent pins or
connector rings. Repair or replace damaged connectors immediately. Dirty connectors can
limit the accuracy of your measurements. Damaged connectors can harm the instrument.
Connection of cables carrying an electrostatic potential, excess power, or excess voltage can
damage the connector, the instrument, or both.
Connecting Procedure
1. Carefully align the connectors. The male connector center pin must slip concentrically
into the contact fingers of the female connector
2. Push connectors straight together. Do not twist or screw them together. A slight
resistance can usually be felt as the center conductors mate.
3. To tighten, turn the connector nut, not the connector body. Major damage can occur to
the center conductor and to the outer conductor if the connector body is twisted.
4. If you use a torque wrench, initially tighten by hand so that approximately 1/8 turn or
45 degrees of rotation remains for the final tightening with the torque wrench.
Relieve any side pressure on the connection (such as from long or heavy cables) in order
to assure consistent torque. Use an open-end wrench to keep the connector body from
turning while tightening with the torque wrench.
Do not over-torque the connector.
Disconnecting Procedure
1. If a wrench is needed, use an open-end wrench to keep the connector body from turning
while loosening with a second wrench.
2. Complete the disconnection by hand, turning only the connector nut.
3. Pull the connectors straight apart without twisting or bending.

1-4 Instrument Care and Preventive MaintenanceGeneral Information
ESD Caution
The MT8220T, like other high performance instruments, is susceptible to ESD (electrostatic
discharge) damage. Coaxial cables and antennas often build up a static charge, which may
damage the MT8220T input circuitry (if allowed to discharge by connecting directly to the
MT8220T without previously discharging the static charge). MT8220T operators must be aware of the potential for ESD damage and take all necessary precautions.
Operators should exercise practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices,
equipment, and practices. Because these apply to the MT8220T, Anritsu Company
recommends that any static charges that may be present be dissipated before connecting
coaxial cables or antennas to the MT8220T. This may be as simple as temporarily attaching a
short or load device to the cable or antenna prior to attaching to the MT8220T. Remember
that the operator may also carry a static charge that can cause damage. Following the
practices outlined in the above standards ensures a safe environment for both personnel and
equipment.
RF Input Warning
The BTS Master is a sensitive measuring instrument designed to measure low power levels.
Avoid damaging this sensitive circuitry by observing the maximum input levels printed on
the instrument connector labeling and specified in the product technical data sheet.
Typical maximum input is +30 dBm (±50 VDC) and could be less if additional features, such
as a preamplifier, are in use. Be sure to review the product technical data sheet or Anritsu
website for recommended components and accessories that can help you protect your
instrument. These include a variety of adapters, attenuators, filters, and RF detection
accessories.
