MT8801C
Radio Communication Analyzer
300 kHz to 3 GHz
Keyboard sold separately
For Worldwide Communications Systems
Every major radio communication system in the world,
including GSM/DCS1800/PCS1900, CDMA, IS-136A, PDC,
PHS and DECT, can be evaluated using just one MT8801C
Radio Communication Analyzer, covering the 300 kHz to
3 GHz frequency band in one hardware platform, and the
dedicated measurement software options. The call processing test and sensitivity test using loopback method are possible for GSM/DCS1800/PCS1900, CDMA, IS-136A and DECT.
In addition, connection testing, as well as send testing while
communicating, are also possible for PDC and PHS measurement by using the call processing function, and the PDC
uplink RCH can be monitored (RSSI, estimated error rate) too.
FM radio transmission/reception tests are simplified by using
the optional analog measurement function, and the optional
spectrum analyzer function covering 10 MHz to 3 GHz is very
useful for maintaining as well as measuring spurious near carrier on production lines. GPIB and RS-232C interfaces are
standard, so MT8801C can be incorporated easily into automated production lines or on-site automated testing systems.

Unique High-Speed Measurement Method
The time required for testing equipment on production lines is
greatly reduced using the high-speed adjacent channel power
and occupied bandwidth measurement functions based on
Anritsu’s proprietary measurement algorithm and DSP (Digital
Signal Processing). Furthermore, major transmission test items
such as transmission frequency, modulation accuracy (phase
error), transmission power, rise/fall characteristics of burst
wave, adjacent channel power, etc., can be measured and
judged pass/fail for limit value of the each item.

Rapid Measurement
Batch Measurements of Transmission Test Items
Example for PDC/PHS, only about 1 second is
required to measure all major transmission test items,
including frequency, modulation accuracy, origin offset, transmission rate, transmission power, leakage
power during carrier-off, rise/fall edge characteristics,
occupied bandwidth, and adjacent channel power.
Pass/fail decisions for limit value of each test item can
also be displayed.
Measurement of Antenna Power
Rise/Fall Edge Characteristics
Antenna power rise/fall edge characteristics can be
measured simultaneously with antenna power measurements. In addition, the marker points can be
moved and the power can be read directly with 1/10
symbol resolution.
Calibration Functions
A built-in thermocouple power sensor is used for calibration, providing accurate measurement of absolute
values such as average power with burst signal and
leakage power during carrier-off. There is no need for
other instruments; Just one press of the CAL key during measurement performs calibration.
Modulation Analysis
The user can display the waveform as either frequency
deviation, eye diagram or constellation diagram to
easily show any irregularities in the modulation.
Constellation Display Functions
The I/Q vector components of measured signals are
displayed. The frequency error, RMS/PEAK vector
errors, and origin offset can be shown on the same
screen.

Wide-Band Power Meter
The power meter with built-in thermocouple power
sensor can accurately measure power between 0 and
+40 dBm.
Receiver Sensitivity Measurement
This function displays the error count and error rate in
the RF input or DATA/CLOCK input measured signal.
Adjacent Channel Power Measurement
The MT8801C can measure adjacent channel power
for each communication system at high speed.
Call Processing Function
The MT8801C acts as a pseudo base station permitting to judge pass/fail for registration, origination,
termination, communication, handover (PHS: TCH
switching type only), disconnection from network and
disconnection from mobile station at the sequence
monitor screen.
Bit error rate measurement (IS-136A)
Adaptive BER Receiver Testing
For DECT measurements, there are one FER and two
BER measurements. The two measurements, one
quick and the other full, allow the number of samples
required to conclude a test to be adapted to suit the
receiver being tested.

Transmission Measurement
Characteristics such as frequency, power, and frequency deviation can be measured easily.
AF Low Impedance Output (Option 04)
This option converts the output impedance of the AF
oscillator of the Option 01 Analog Measurement to
low impedance. It permits direct driving of an external
speaker connected to the AF output connector.
Reception Measurement
An FM modulated signal is output to permit measurement of the frequency and level of the AF signal from
a receiver, as well as SINAD and distortion.
AF Measurement
An AF signal is output to measure the frequency, level
and distortion of the AF signal at the DUT.
Analog Measurement
Analog Measurement Function (Option 01)
The MT8801C has general analog measurement functions too. Efficient FM TX/RX testing is made easy by
built-in signal generator, AF oscillator, RF analyzer
(power meter, frequency counter, FM measurement)
and audio analyzer functions. This function is especially useful for the IS-136A analog test.
Transmission Measurement with SG Function
Transmission characteristics can be measured by outputting an FM RF signal from the built-in signal generator.

Spectrum Analyzer Function (Option 07)
The spectrum analyzer with synthesized local covers
a frequency range of 10 MHz to 3 GHz with a resolution of 1 Hz. In addition to a C/N of –115 dBc (100 kHz
offset), the RBW can be set to 300 Hz to 1 MHz, the
VBW to 3 to 100 kHz, and the sweep time in the frequency domain to 100 ms to 1000 s (1 ms to 1000 s in
time domain).
High-Accuracy Measurement
The total level accuracy is an astonishing ±1.5 dB due
to the analyzer’s excellent linearity, and the level calibration function. Moreover, the average noise level is
just –85 dB max. (at 10 MHz to 1 GHz), and the secondary harmonic distortion is –60 dB max. (100 MHz
to 1.5 GHz).
Convenient Functions
The analyzer has a full lineup of useful functions
including marker, delta marker, and gate sweep functions. It also has advanced displays such as average,
max. hold, cumulative and overwrite. Trace A and
Trace B can be measured on a dual screen in the frequency domain, along with noise power, C/N, occupied bandwidth, adjacent channel power, and average
power of burst signal.
