Aperçu



This document contains a list of known issues for NI-RFmx TD-SCDMA 2.1.

Each issue appears as a row in the table and includes the following fields:

  • Issue ID - The number in at the top of each of the cells in the first column. When you report an issue to NI, you may be given this ID, you can also find IDs posted by NI on the discussion forums or in Knowledge Base articles.  "N/A" indicates that there is no ID assigned to the issue.
  • Issue Title (in italics) - Describes the issue in one sentence or less.
  • Problem Description - A few sentences which describe the problem in further detail. The brief description given does not necessarily describe the problem in full detail, and it is expected that you may want more information on an issue. If you would like more information on an issue, contact NI and reference the ID number given in the document.
  • Workaround - Possible ways to work around the problem. The workarounds that appear in the document are not always tested by NI and are not guaranteed to resolve the issue. If a workaround refers you to the NI KnowledgeBase, visit www.ni.com/kb/ and enter the KnowledgeBase number in the search field to locate the specific document.
  • Reported Version - The earliest version of NI-RFmx in which the issue was reported. If you discover the issue appears in an earlier version of NI-RFSG than is reported in this field, report the discrepancy to NI to have the field updated.
  • Resolved Version - Version in which the issue was resolved or was no longer applicable. "N/A" indicates that the issue has not been resolved.
  • Date Added - The date the issue was added to the document (not the reported date).

Known Issues by Severity

567473 ModAcc measurement is limited to analyze signals with an average power higher than -40dBm.
570432 The ModAcc Midamble Shift property does not conform to the 3GPP standard.
570431 The values of the ModAcc Midamble Shift property are limited to values ranging from 0 to 16, inclusive.
ID Known Issue
567473

ModAcc measurement is limited to analyze signals with an average power higher than -40dBm. 
For input signals with lower input power synchronization fails.

Workaround: Ensure that the average input signal power is above -40dBm.


Reported Version: 2.1    Resolved Version: N/A    Added: 02/15/2016
570432

The ModAcc Midamble Shift property does not conform to the 3GPP standard.
The ModAcc Midamble Shift property does not conform to the 3GPP standard because the shift is applied in the wrong direction.
Workaround: Manually calculate the midamble shift using the following equation: RFmx MA Shift = (128 - 3GPP MA Shift) mod 128


Reported Version: 2.1    Resolved Version: N/A    Added: 02/15/2016
570431

The values of the ModAcc Midamble Shift property are limited to values ranging from 0 to 16, inclusive.
With this limitation, only the midamble shifts of 0, 8, and 16 chips which conform to the standard can be used instead of 0,8,16, ..., 120.
Workaround: N/A


Reported Version: 2.1    Resolved Version: N/A    Added: 02/15/2016
