Capture Log Data via Network with the NGM200 Series

Description

Is it possible to stream the log data via the network? I could not find any command for a streaming mode in the manual.

Resolution

In fact there is no dedicated streamin mode available for this devices. However when using the fast log mode it is possible to redirect the data to SCPI (FLOG:TARGet SCPI) and capture all the data with the FLOG:DATA? command in binary blocks:

  • The header begins with the number of following bytes (length)
  • Length
  • Block Data (8 Bytes / 64 bits per Sample divided into 4 Bytes / 32 bits for the voltage as well as for the current)

Please find an example in the attachment of this FAQ article showing how to handle this mode using Python with the RsInstrument module.
