 Default:Channel 1 (See OFDMA Standard Presets Table.)

Measure Input Channelselects one of the input channels as the source for the STC Space Time Coding (STC) allows the transmitter to transmit signals (information) both in time and space, meaning the information is transmitted by two antennas at two different times consecutively./MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. measurements.

How the Measure Input Channel parameter affects the VSA depends on the status of the Enable Matrix Decoder parameter.

• When the Enable Matrix Decoder parameter is cleared, the Measure Input Channel parameter selects one of the input channels for regular OFDMA analysis. For example, if Antenna 0 is selected, then the Antenna 0 pilot pattern is used for OFDMA analysis for the selected input channel.
• When the Enable Matrix Decoder parameter is selected, the Measure Input Channel parameter (along with the Override Transmit Antenna Pilot Pattern parameter) selects which Tx/Rx path to isolate from the MIMO traces into legacy traces for better visibility. These legacy traces include Eq Ch Frequency Response, Eq Ch Impulse Response, Common Pilot Error, and Eq Ch Freq Resp Adj Diff.
