Upgraded Software Improves 3GPP LTE Measurements

Oct 30, 2008 11:55 AM, MD&D News Staff

Enhanced test and analysis software for the Anritsu MS269xA signal analyzer and MG3700A vector signal generator allow users to make highly accurate measurements on LTE (Long-Term Evolution) Uplink and Downlink signals. The combination of the test sets and software facilitates testing of 3GPP LTE-compliant mobile terminals, base stations, and components.

For the MS269xA, both the LTE Uplink and Downlink packages now include analysis at the resource block level. Analysis resolution can be set to the physical channel, resource block, subcarrier, and symbol. Error vector magnitude (EVM), a key figure of merit for LTE, is available at any resolution. Users can quickly test all varieties of unwanted emissions described in the specification with the MS269xA. By pressing a single button, occupied bandwidth (OBW), ALCR, and out-of-band spurious emissions measurements can be made.

IQproducer, Anritsu’s waveform-generation software, has been enhanced to allow users to define test waveforms for the Uplink or Downlink. While standard test waveforms are not yet part of the specification, IQproducer provides users with a rich set of parameters and variations to create standard and unique waveforms for LTE signal analysis. When IQproducer is installed on the MS269xA and the MG3700A, the instruments can up convert and generate any waveform, including Uplink and Downlink data frames, and Uplink Random Access Preamble signals.

The LTE Uplink and Downlink analysis packages are $18,500 each. The LTE waveform generation software for the MS269xA signal generator option and the MG3700A vector signal generator is $5,500. The base price of the MS269xA series starts at $37,000, while the MG3700A has a base price of $29,000.
