Issues Resolved:

• [Basic Core] Frequency Counter function is broken

  • Reported against VSA 2023 Update 1.0. The marker window displays "Freq 0: Not valid for this trace data"

• [Basic Core] Ext Mixer Dual conversion mode does not work with M1971V

  • Reported against VSA 2023. Using M1971V with PXA - no signal is seen when Dual Conversion mode is selected.

• [Basic Core] Wrong channels using pre-Keysight M3102A modules

  • Reported against VSA 2023 Update 2.0 BETA4.

• [5G NR] SRS EVM shows 0 % even when changing the below parameters - Sequence ID, Transmission Comb, and Comb Offset

  • Reported against VSA 2022 Update 1.0

• [5G NR] Decoded Info table only returns two of the four generated slots for PUCCH

  • Reported against VSA 2023. the Decoded Info table only returns Slots 8 and 9, not Slots 18 and 19

• [5G NR] When CRC fails, "Failed Code Blocks" result in Decoded Info table is not correct

  • Reported against VSA 2023. Failed Code Blocks shows: None at CC0’s Slot = 3 & 5, but the actual failed code block is 10.

• [5G NR] Wrong Resource Grid for 240kHz numerology

  • Reported against VSA 2023. Grid size of 34 for 240 kHz numerology. This should be 32.

• [5G NR] MIMO signal, Layer1 constellation is distorted

  • Reported against VSA 2022 Update 1.0. The constellation diagram for Layer 1 is much worse than Layer 0.

• [5G NR] Slot Summary table doesn't return the correct SF and Slot numbers

  • Reported against VSA 2023

• [5G NR] SSB Decoding fails with high LO Feedthrough

  • Reported against VSA 2023. SSB performance is impacted by very high LO feedthrough and the decoding fails in most of the SSBlocks.

• [5G NR] PUCCH Format 3 CSI-2 decode fail

  • Reported against VSA 2023 Update 2.0 BETA2. PUCCH Format 3 CRC fails when CSI-2 is transmitted.

• [Digital Demod] Memory leak causing crashes

  • Reported against VSA 2023. Running tests with DigDemod continuously and sees the system crash every two weeks after the VSA consumes 30GB of memory.

• [WLAN] PSDU CRC status only checks first user

  • Reported against VSA 2023. A math error causes only the first user to be checked in when reporting the PSDU CRC status in the burst info trace.
