5. (V4.41) Switching back to the internal LCD display does not work if the single display
"MONITOR" is configured during power on and no external monitor is connected.
This problem only occurs for certain display revisions. Press SETUP –SYSTEM INFO – HW INFO. The
HWC in line FSQ indicates 01 if this display revision is installed.
Note: This issue is already fixed in V4.51 SP1
6. (V4.51) The analyzer application crashes if the external tracking generator (FSP-B10) is switched
on, the Gated Sweep is active and the Gate Adjust softkey is pressed.
Note: This issue is already fixed in V4.51 SP1
7. (V4.51) ACP Measurement: Wrong power measurement values are displayed if the recall of a save
set with active noise correction is performed and the noise correction is switched off
afterwards.
Note: This issue is already fixed in V4.51 SP1
8. (V4.51) ACP Measurement: Wrong unit indication for absolute power results with more than 3
adjacent channels
The measured ACP powers are indicated with unit dB instead of unit dBm, if following settings are used:
- CP/ACP ABS
- Number of Adjacent Channels > 3
The numerical results are not affected.
9. (V4.51) Spurious Emission Measurement: The electronic attenuator is not switched off
The Spurious Emission Measurment configuration does not support the electronic attenuator (FSU-B25) but
is not automatically switched off. This is now corrected.
10. (V4.51) SEM Measurement: The required Number of Sweep Points is not set.
The follow configuration files for EUTRA/LTE Uplink needs 30001 sweep points to be set:
- BW_01_4_MHz.xml
- BW_03_0_MHz.xml
- BW_05_0_MHz.xml
The number of sweep points is no automatically adjusted to this value. This has now been corrected.
Note:
The number of sweep points is not set to it's previous value if the SEM measurement is switched off
or another SEM standard file is loaded.
11. (V4.51) Gated Statstics Measruement: Waring "Gate periode exceeds I/Q capture time" is
indicated.
The validation of the gate settings range is now corrected and the size of the available statistics I/Q capture
buffer is increased.
12. (V4.51) FSP-B10: Wrong limitation of the maximum number of sweep points using TTL interface.
E.g. a SMA100 supports up to 2000 as the maximum number of sweep points using TTL interface for
External Generator Option. The analyzer application erroneously allows 2001 points in that case due to a
rounding problem.
13. (V4.51) FSP-B10: SMF does not go to LOCAL state after being used as external tracking
generator.
14. (V4.51) FSU-B21: Wrong state indication for CVL table usage after recall.
After recall of a save set with external mixer on and conversion loss table (CVL) active, the band table does
not indicate the usage of the CVL table. But the correction values of the CVL table are taken into account.
Improvements with Service Pack 1
Service Pack 1 corrects the following issues. The version numbers in brackets indicate the version in which
the issue was observed for the first time.
1. (V4.61) Noise Correction: Setting the TRACE mode to VIEW deactivates the noise correction.
2. (V4.61) A frequency domain sweep does not terminate.
