Error command with NI Interactive Control

Dear All,

I got a problem when I use NI Interactive Control(NIIC).

I can successfully connect my PC and Instrument.

After I write the command "*OPC?", I could get the correct return data.

(correct return data = Instrument Name)

But when I try another command, it will show error.

I write command: CALCulate:Data:SNP:PORTs:SAVE "1,2,3,4","C:\User\Instrument\Downloads\test11302.s4p" 

and push the "write button"

After the above action, I got the wrong message.

Error 1: Return Data form show "Write operation error" and error code "VISA: Hex 0xBFFF00A6"

Error 2: It changed my command text(Red Square)

"User\Instrument" was changed to "UserInstrument" (Blue line)

"Downloads" was changed to "rownloads" (Green line)

This part is the most confusing for me.

PC: Windows 10

Software: NI Interactive Control

Hardware: USB-GPIB-HS

Instrument: PNA N5227B
