ML8720B Product Features
High performance scanner for drive test systems :
– very good sensitivity (-117 dBm WCDMA measurement capability)
– ‘true’ RAKE receiver (1 – 6 fingers), 1.5 chip resolution
– dual scanner supports antenna diversity (3GPP TS 25.215 v4.2.0 § 5.1.1)
Key features for drive test systems :
– higher sensitivity to record coverage of Node B when UE looses signals
– true RAKE receiver and antenna diversity captures real primary signal cell coverage, multipath and
handover environment
Antenna Gain Specifications
The antenna gain (*) for a standard composition is stored in the internal memory of the ML8720B W-CDMA Area Tester.
Therefore, measurement value can be corrected without inputting user antenna gain vs frequency by setting the antenna
correction to the standard value.
Our UMTS antenna (reference is Z0516) properties are as follow :
Frequency (MHz) Relative gain of antenna (dB)
