Hello, this is my first time at this forum. I wonder, does anyone know how to query the E4440A PSA to find out when the required number of samples have been averaged together? I thought "AVERage:COUNt?" would do it but this only returns the number I set with "AVERage:COUNt" so is of no help in knowing when enough sweeps have been averaged together. Also "*OPC?" does not appear do what I am looking for, it doesn't seem to tie to average counts.
I'd be fine with a polling solution but it needs to be one that uses SCPI commands or something that comes with the standard DLL as I am using LabVIEW and not .NET.
thanks in advance.

Welcome to this forum.
If you turn on averaging (aver:state on), and if you set the analyzer to single sweep (init:cont off) and if you set the averages to 100 (aver:count 100), then if you send the command to start the measurement (init:imm) and if you send the command to check for operation complete (*OPC?), the instrument will only return a “1” when all 100 averages have completed.
Hope ths helped -
