How the Test Set Is Used
The E6607A/B/C Wireless Communication Test Set is typically used in a production test environment
where mobile devices are being calibrated and verified in a “non-signalling” mode (that is, in a mode of
operation which does not involve call processing, and which relies instead on test functions which are
built into the device under test).
The test controller communicates with both the DUT and the test set to coordinate Rx and Tx test
operations and to collect test results. However, both the DUT and the test set perform their own
independent operations during the process (for example, internal test routines run by the DUT, and
sequences run by the test set).
Receiver Testing
The source within the test set can supply test signals to the DUT for the purpose of receiver testing.
Typically the source plays a waveform which has been downloaded to the test set (for example, a .wfm
file generated using Agilent Signal Studio or some other application). In receiver testing, the test set is
providing the necessary stimulus for measurements which are performed by the DUT itself, using its
built-in self-test capabilities. The test results (bit error rate, for example) come back to the controller
from the DUT rather than from the test set.
Transmitter Testing
The signal analyzer within the test set receives and measures signals from the DUT for the purpose of
transmitter testing. Because the DUT is not being operated in a call-processing mode, the measurements
