The UMTS Master model MT8220A is a handheld Node B analyzer designed to aid RF engineers and technicians during installation, deployment and maintenance of WCDMA/HSDPA Node B equipment. The MT8220A combines the functionality of a transmitter analyzer (WCDMA/HSDPA, GSM/GPRS/EDGE), channel scanner interference analyzer, and the field proven Spectrum Master (MS2721A) spectrum analyzer into one lightweight, handheld, test tool weighing less than 6.5 lbs (2.9 kgs).
Applications:
WCDMA/HSDPA Node B transmitter performance testing (installation, deployment, maintenance) Four WCDMA/HSDPA Options to analyze node B performance in detail by connecting the UMTS Master to node B or connecting an antenna and capturing WCDMA/HSDPA signal Over The Air
Capture WCDMA/HSDPA signals using Over The Air (OTA) measurement with a portable antenna while sitting in the car
Two GSM/GPRS/EDGE options to analyze base station performance in detail
Spectrum Analysis anytime, anywhere
Channel Scanner measures the power of multiple transmitted signals at one time
Identify intermittent interference using a spectrogram display and locate the interference signal using the signal strength meter
Features
WCDMA/HSDPA Multi-Channel ACLR measurement displays up to four main channels and up to four adjacent channels
WCDMA/HSDPA Over The Air (OTA) - displays six scrambling codes in a bar graph format. For each scrambling code, CPICH in dBm, Ec/Io in dB, Ec in dBm, and plot dominance in dB is displayed.
WCDMA/HSDPA RF measurements provides ACLR, multi-channel ACLR, spectral emission mask for quick node B analysis
Demodulate WCDMA/HSDPA signal and display the selected code constellation and measure code variation over time.
GSM/GPRS/EDGE RF measurement provides views of single channel spectrum, multi-channel spectrum, power versus time (Frame), power versus time (slot) with mask for quick base station analysis.
Using GSM/GPRS/EDGE demodulator option automatically demodulates GSM or EDGE signal and displays the applicable vector diagram.
GPS option saves measurement with location information.
GPS option enhances the frequency accuracy of the UMTS Master's internal OCXO oscillator.
Handheld, lightweight battery-powered design
Large daylight viewable transflective color display
Lightweight at only 6.4 lbs (2.9 kgs)
Custom software that plots data from both GSM channel power and UMTS/WCDMA P-CPICH (Power in the Primary Common Pilot Channel) measurements for EMI analysis
