E1962B functionality overview

With advanced features and superior performance, the E1962B is designed for high-vol-

ume manufacturing and wireless device development, allowing you to finalize product

designs and minimize time to volume.

CDMA forward link emulation

The fully-coded IS-2000 forward-link emulation supports radio configurations 1 through

5, and 11, as well as all supplemental channel data rates associated with those config-

urations. Comprehensive signal generation capabilities including all applicable CDMA

channels, modulation, and an AWGN source (1.8 MHz minimum bandwidth). Flexible user

control of the forward link emulation is provided through easy-to-use front panel control

and remote GPIB. Option E1962B-401 adds cdma2000 Release A protocol support and

includes the F-BCCH and F-CCCH channels. E1962B-410 adds cdma2000 1x Advanced

support and includes the F-ACK channel for early termination.

CDMA authentication

Option E1962B-403 adds authentication capabilities when operating in the active cell

modes using the IS-95 or IS-2000 systems. Authentication supports two, one-button

commands: unique challenge and SSD update. The global challenge function can be

turned on or off to support authentication with most call processing functions. User

authentication parameters include A-key (decimal), RAND (hex), RANDU (hex), and

RANDSSD (hex). The reported global challenge results include the AUTHU expected

value, the AUTHU received value and a pass/fail result and the RANDC expected value,

the RANDC received value, and a pass/fail result. Other results include the count and

AUTH_MODE. The reported unique challenge results include the AUTHU expected value,

the AUTHU received value and a pass/fail result. Pass/fail results are also available for

SSD updates.
