Reply To: VSG60A Windows C API

Hi Mike,

You are correct about the float* parameter. It should be const, and the data is not modified by the API. I will see about getting this in a future update. Yes, you are safe to cast.

I can’t reproduce the issue you are seeing regarding RF output on/off. I wrote a short script to attempt to reproduce. Maybe you could try to run this? If all else fails, maybe you could whip up a simple script I could try to run and reproduce? See code below.

This function simply turns on and off the RF output in 1 second intervals. I observed the power going on and off at these intervals.

void testRFOutput()
{
    int handle = -1;
    VsgStatus vsgSts = vsgOpenDevice(&handle);
    if(vsgSts != vsgNoError) {
        printf("Unable to open VSG\n");
        return;
    } 

    vsgSetFrequency(handle, 1.0e9);
    vsgSetLevel(handle, -40.0);

    while(true) {
        vsgSetRFOutputState(handle, vsgTrue);
        vsgOutputCW(handle);
        Sleep(1000);
        vsgSetRFOutputState(handle, vsgFalse);
        Sleep(1000);
    }
}

Look forward to your response.

Regards,
Andrew
