UL-SCH—HARQ Process States
The PUSCH transmission is controlled based on the HARQ packet number.
When using multiple instruments as shown in the tree view, inaccurate test data may occur if a combination of the GUI and SCPI is used to set or modify the instrument and test parameters. The software will not reflect changes made outside of the GUI even with the use of the Update from Instrument button. For all tests, use only one method to configure the settings, GUI or SCPI.
When configuring multiple instruments with SCPI instead of using the GUI, the commands must be executed for each instrument.
When using multiple instruments as shown in the tree view, after clicking the State On button, all settings for this window gray out and cannot be changed. To change the settings, first click the State Off button.
