The Anritsu MT8820B is a radio communication analyzer that combines signaling and RF measurement capabilities for research, development, manufacturing, and maintenance of mobile devices across multiple wireless technologies. It delivers dual-port RF testing, simultaneous two-device measurement via Parallelphone™ technology, and transmission measurement speeds twice that of its predecessor—all while consuming 30% less power than the MT8820A.
## Technical Specifications
**Supported Technologies**
• W-CDMA/HSPA/HSPA Evolution/DC-HSDPA/4C-HSDPA
• GSM/GPRS/EGPRS
• CDMA2000 1X / 1xEV-DO Rev. 0 / 1xEV-DO Rev. A
• TD-SCDMA/HSPA
• PHS/Advanced PHS
**Frequency Range**
30 MHz to 2.7 GHz; optional 3.4 GHz to 3.8 GHz
**Power Consumption**
Typical 125 W per UMTS port (30% reduction vs. MT8820A at 185 W)
## Key Features
**RF Measurement & Testing**
Performs calibration, RF parametric testing, and functional/quality assessments. Detailed failure diagnosis and evaluation of mobile device transmission/reception parameters. RF Tx/Rx characteristics testing for multiple communication formats with a single unit when optional software and hardware are installed.
**Parallelphone™ Measurement**
Simultaneous and independent testing of two mobile terminals reduces equipment costs and floor-space requirements.
**Transmission Performance**
High-speed Tx measurement capability—twice the speed of MT8820A—significantly improves manufacturing throughput.
**Thermal Design**
Side-to-back exhaust flow enables closer unit placement and space savings versus side-to-side exhaust designs. Reduced fan noise.
