Using Signal Studio Setup Files (LTE-Advanced)

The VSA supports importing Keysight Signal Studio LTE Long Term Evolution waveform setup files created using N7624B Signal Studio for 3GPP LTE, versions 7.9 and newer, or N7625B Signal Studio for 3GPP LTE TDD Time Division Duplex: A duplexing technique dividing a radio channel in time to allow downlink operation during part of the frame period and uplink operation in the remainder of the frame period., versions 3.0 and newer. You can import an LTE-Advanced signal definition created in Signal Studio to configure the analyzer to demodulate and analyze the generated waveform.

Using a Signal Studio Setup File to Setup the VSA

To import the Signal Studio LTE-Advanced waveform setup file, click File > Recall > Recall Signal Studio Setup. In the Recall Signal Studio Setup dialog box, select "Setup (*.scp;*.xml)" in the Files of Type drop-down list, and then open the file. When the signal studio file is opened, all relevant measurement, LTE-Advanced setup, and LTE-Advanced frame definition parameters are imported from the Signal Studio file.

In Signal Studio, the Carrier Type parameter indicates the direction of the LTE/LTE-Advanced carrier and the version of the standard supported. The 89600 VSA LTE-Advanced demodulator can recall Signal Studio setup files with the following carrier types:

Basic LTE-A FDD Frequency Division Duplex: A duplex scheme in which uplink and downlink transmissions use different frequencies but are typically simultaneous. R10 Uplink (2010-12)
Basic LTE-A FDD R10 Downlink (2010-12)
Basic LTE-A TDD R10 (2010-12)

Signal Studio does not support saving more than one frame's allocations into a setup file. For multi-frame (Waveform Generation Length greater than 1 Frame for FDD or greater than 2 Frames for TDD) Signal Studio setup files, the 89600 VSA can recall the measurement parameters but will not recall user mappings and will instead perform a power-based resource block autodetection.
