Some general questions, suggestions, and ideas,
– Ensure you are transmitting at the same sample rate as the recording occurred.
– Depending on the settings used when the recording was made, it’s possible the noise floor of the BB60 is contributing to the transmission. Is the SNR good enough on the re-transmission?
– Did any compression occur during recording? aka IF overloads?
– Are you transmitting at the right power?
– Are you running both devices simultaneously? If yes, that could cause signal drop outs, or if both devices were active during the recording, the recording could be compromised (dropped samples). In general, not every PC is capable of running multiple of our high speed USB devices.
– Do you have anyway to verify the recording is good by inspection? (aka software inspection?)
– Do you have any known good recordings you can try to transmit with the VSG60?
– What is the make/model of your PC? Are you using any USB hubs?
– Is your recording on an SSD with necessary read/write speeds? I’m assuming you are using the streaming output mode in the VSG60 software which is going to read from disk in real-time.
