Additional GSM/GPRS/Edge options for the UMTS Master enhance the analyser's existing testing capability.
The UMTS Master combines the functionality of a WCDMA transmitter analyser and Anritsu's field-proven Spectrum Master MS2721A spectrum analyser into one lightweight, handheld, test tool weighing less than 2.7kg.
The spectrum analyser mode frequency range is a continuous 100kHz to 7.1GHz.

Tester checks 3G basestations at 100km/h
Anritsu has launched the ML8720B, a portable W-CDMA tester for the evaluation of radio propagation characteristics in the area surrounding 3G mobile basestations.
The product also features displayed average noise level (DANL) as low as -153dBm (typical) in a 10Hz resolution bandwidth at 1GHz.
The UMTS Master, when equipped with the new HSDPA option, can make all the measurements listed in the 3GPP specification for HSDPA basestation performance testing.
Field technicians and wireless engineers can quickly check basestation performance using any of the three options - RF measurement, demodulation and over the air (OTA).
All key RF measurements, including band spectrum, channel spectrum, spectral emission mask and ACLR, can now be made on HSDPA signals with the UMTS Master.
An RF summary screen allows RF measurements to be quickly and easily viewed on the UMTS Master's 8in SVGA colour LCD screen.
The WCDMA/HSDPA demodulator option allows the UMTS Master to demodulate HSDPA signals and display CDP, code variations over time, and the constellation for the selected code.
All standard WCDMA demodulation measurements can also be made.
The OTA option displays six scrambling codes in a bar graph format.
For each scrambling code, CPICH in dBm, Ec/Io in dB, Ec in dBm, and pilot dominance in dB are shown in tabular format.
Additionally, users can see OTA total power in dBm.
Testing HSDPA signals is extremely easy with the UMTS Master.
In the pass/fail mode, the UMTS Master stores the five test model conditions specified in the 3GPP specification as a reference for basestation testing.
After selecting the test model, the UMTS Master displays whether the basestation has passed/failed the test.
Custom lists, including min/max for each parameter, can be created using Anritsu's Master Software Tools and downloaded into the UMTS Master.
All results can be displayed in a tabular format with clear identification of pass/fail results, including min/max thresholds.
The UMTS Master's frequency range up to 7GHz allows flexibility to perform measurements on both WCDMA/HSDPA and GSM/GPRS/Edge signals over all mobile frequency bands.
Technician and RF engineers can connect the UMTS Master to any basestation for accurate RF and modulated signal measurements.
GSM/GPRS/Edge RF measurements provide views of single-channel spectrum, multichannel spectrum, power versus time (frame), and power versus time (slot) with mask.
The UMTS Master can also demodulate GSM/GPRS/Edge signals and display the results of detailed measurements for transmitter modulation performance analysis.
Delivery is 8 weeks ARO.
