Hi everybody. I am new in this forum. I hope we can exchange our knowledge.
It's very hard to find what I need: i.e. , a simple communication with network vector analyzer in C#.
I am trying to write a C# program to memorize the NVA trace in a C# vector. There are many commands that work, except the ones that allow me to manage the trace.
In the Visual Studio 2019 environment this command: “str.WriteString (" CALC:DATA? FDAT "); ", display this error:
“RohdeSchwarz.RsInstrument.InstrumentStatusException: ''TCPIP0::192.168.1.10::hislip0': Instrument error detected: Query interrupted' ”
At the same time the NVA shows this generic error: “Remote error -410: Query interrrupted”
) How can I fix it?
) How can I store a trace of the NVA in a C# vector?
) Can you suggest me a manual for programming in C# with NI-VISA library for NVA?
Thanks
The test code:
“
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using RohdeSchwarz.RsInstrument;
namespace RsInstrument_Hello_World_Example
{
class Program
{
static void Main()
{
RsInstrument instr;
RsInstrument.AssertMinVersion("1.10.1");
try {
instr = new RsInstrument("TCPIP0::192.168.1.10::hislip0");
}
catch (RsInstrumentException e)
{
Console.WriteLine($"Error initializing the instrument session:\n{e.Message}");
Console.WriteLine("Press any key to finish.");
Console.ReadKey();
return;
}
instr.WriteString("*RST");
instr.WriteString("CALC:PAR:SDEF 'Trc1','S21'");
instr.WriteString("DISP:WIND:TRAC:FEED 'Trc1'");
instr.WriteString("CALC:DATA? FDAT");//<----- this line doesn't work!
instr.Dispose();
}
}
}
