NMullinParticipantHi Andrew, thanks for the reply since this post I have been conducting some tests to verify these points. I did not create the recording so cannot fully verify that no IF overloads occurring when GSM was recorded but visually inspecting the signal with other measurement devices confirms that the signal is suitably clean.
I assumed the test PC’s that were purchased specifically for the VSG60A and the BB60C were in spec and from what I have seen they may not be. We purchased 3 Dell micro OptiPlex’s (3090, 5070) with 8GB of ram and 256GB ssd/nvme. I will post a picture from running winsat but it appears the read speeds do not meet the requirements for the VSG60A (in streaming mode). The later test systems are the micro OptiPlex 5000, these have 16GB of ram and faster nvme drives, we have seen the best results when using these test systems.
These performance issues have only surfaced recently as historically we have only used steaming mode in the VSG60 software but recently I have made tests using the ARB mode as to my knowledge is the only supported mode with single playback feature. As the recording is loaded using the old test systems the software hangs for a considerable amount of time before other actions can be performed. Changing dBm levels when RF on and MOD on are enabled also hangs the software. This does not happen with the newer Dell OptiPlex systems so raised a red flag.
We are currently in the process of updating the test PC’s and will see if this resolves the issue. For now is there anyway of playing a recording once through streaming mode instead of having it loop can this feature be added to the VSG60 software?Attachments:
