Options 6113-313 and 6113-440 extend the capability of the 6113 EDGE base station test set to allow GPRS and EDGE-capable base stations to be tested. These options are available on both new units and as an upgrade to existing test sets.

GPRS and EDGE technology introduce new channel types, and for EDGE, 8-PSK modulation in addition to GSM’s and GPRS’ GMSK modulation. This alters the RF specifications and performance of the base station and with it brings a corresponding need to test these new features. The GPRS and EDGE options support the following EGPRS channel types:

• CS-1 to CS-2 GMSK modulation (GPRS)
• MCS-1 to MCS-4 GMSK modulation (EDGE)
• MCS-5 to MCS-9 8-PSK modulation (EDGE)

When selecting GPRS or EDGE test options, the standard 6113 tests and pass/fail limits are automatically adjusted to match the appropriate test specifications. New tests, such as error vector magnitude (EVM) and receiver BLER are also added for testing 8-PSK signals.

GPRS and EDGE test set parametric performance is equivalent to the standard 6113 test set product specification. The Cell Integrity and Live Test options are not available for GPRS or EDGE.

Base Station Manufacturers Supported
The following BTS manufacturers' specific A-bis software is supported on the 6113 for GPRS and EDGE. If support for other manufacturers is required, please contact us.

* Alcatel
* Ericsson
* Motorola
* Nokia

Software Support
The GSM standards and base station software continue to evolve as new features are introduced. In order to maintain compatibility between the 6113 and the base station under test, annual software support contracts are offered. The software support contract also provides minor enhancements to the 6113 functionality as and when released and access to the Aeroflex Helpdesk for technical support and assistance in using the 6113.
