Fading tests
E5515C/E Option 004 adds a rear panel digital bus that enables fading when it is used
with Keysight’s Baseband Studio for fading solution. In conjunction with the E5106A PXB
baseband generator and channel emulator, the E1962B provides receiver fading tests
with unprecedented accuracy and repeatability, at a very attractive price point. Base-
band I/Q data from the Keysight E5515C/E wireless communications test set is sent via
the digital bus to the N5101A fading card in an external PC. N5106A and associated soft-
ware can be used to perform the user-selected fading profile. After digital fading, AWGN
can be digitally added to the waveform. The resulting waveform is then returned to the
test set via the digital bus for modulation. This solution eliminates almost all associated
calibrations and provides rock-solid repeatability.
Multi-unit synchronization
Option 406 allows any test set to be time-synchronized to another test set that is
running either a CDMA or 1xEV-DO test application or lab application. The multi-unit
synchronization supports simulation of mobile behaviors with two base stations. Typical
applications are idle/softer handoff, pilot detection, and hybrid mode simulation.
