Hello,
I use following timer counter analyzer.
Brand: Pendulum
Model: CNT-90 Incl. Option 30 Built in.
Firmware revision: V1.28
I develop c#.net application for communication with cnt-90 device.You can see below an example part of c# code for measurement.
[DllImport("visa32.dll")]
static extern int viOpenDefaultRM(out int rm);
[DllImport("visa32.dll")]
static extern int viOpen(int rm, string ResourceName, int viAccessMode, int TimeOut, out int vi);
[DllImport("visa32.dll")]
static extern int viClose(int vi);
[DllImport("visa32.dll")]
static extern int viRead(int vi, byte[] buffer, int count, out int retCount);
[DllImport("visa32.dll")]
static extern int viWrite(int vi, string buffer, int count, out int retCount);
public Measure_Frequency()
{
byte[] Buffer = new byte[255];
string Command = ":MEASure:FREQuency?";
int status;
status = viWrite(vi, Command, Command.Length, out RetCout);
if (status != 0)
{
error = "viWrite error!";
return;
}
status = viRead(vi, Buffer, 255, out RetCout);
if (status != 0)
{
error = "viRead error!";
return;
}
// received Buffer assessment procedures
.
.
.
.
}
I communicate with usb port for measurement with cnt-90.When I take a single measurement with our above Measure_Frequency function, there is no problem.But whenI take consecutive six sample measurement with our above Measure_Frequency function some values coming out of bounds.
I receive measurement data from the device with the above example.This is a correct method?
What are your suggestions in this regard?
Thanks in advance.
