AARTSAAPI_StopDevice & AARTSAAPI_StartDevice
Good morning,
We are having a little bit strange issue when using sweep mode with values extended from 3e7 to 6e9 using filter auto extended.
We have a loop to start/stop the meetering from the device, at first round it runs smoothly but when we stop the process using AARTSAAPI_StopDevice and we start it again with AARTSAAPI_StopDevice it inmediatly starts to return empty values. (AARTSAAPI_GetPacket(&deviceHandler, 0, 0, &_packet2) =1 instead of 0).
when setting main/stopfreq value to 80e6 it runs fine. We do not understand why this is happening. Can you help us?
Thanks in advance.
May this code help to reproduce the issue:
AARTSAAPI_Result res;
// Initialize library for medium memory usage
if ((res = AARTSAAPI_Init(AARTSAAPI_MEMORY_MEDIUM)) == AARTSAAPI_OK)
{
// Open a library handle for use by this application
AARTSAAPI_Handle h;
if ((res = AARTSAAPI_Open(&h)) == AARTSAAPI_OK)
{
// Rescan all devices controlled by the aaronia library and update
// the firmware if required.
if ((res = AARTSAAPI_RescanDevices(&h, 2000)) == AARTSAAPI_OK)
{
// Get the serial number of the first V6 in the system
AARTSAAPI_DeviceInfo dinfo = { sizeof(AARTSAAPI_DeviceInfo) };
if ((res = AARTSAAPI_EnumDevice(&h, L"spectranv6", 0, &dinfo)) == AARTSAAPI_OK)
{
// Try to open the first V6 in the system in sweep mode
AARTSAAPI_Device d;
if ((res = AARTSAAPI_OpenDevice(&h, &d, L"spectranv6/sweepsa", dinfo.serialNumber)) == AARTSAAPI_OK)
{
// Begin configuration, get root of configuration tree
AARTSAAPI_Config config, root;
if (AARTSAAPI_ConfigRoot(&d, &root) == AARTSAAPI_OK)
{
// Select the first receiver channel
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"device/receiverchannel") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetString(&d, &config, L"Rx1");
// Use fast receiver clock
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"device/receiverclock") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetString(&d, &config, L"245MHz");
// La magia
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"calibration/rffilter") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetString(&d, &config, L"Auto Extended");
// Start frequency at 75MHz
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"main/startfreq") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetFloat(&d, &config, 30e6);
// Stop frequency at 6000MHz
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"main/stopfreq") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetFloat(&d, &config, 6000e6);
// Set RBW frequency to 1MHz
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"main/rbwfreq") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetFloat(&d, &config, 1.0e6);
// Reference level at -20dBm
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"main/reflevel") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetFloat(&d, &config, 10.0);
/*
// Select iq as output format
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"device/outputformat") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetString(&d, &config, L"iq");
// Set decimation to 1/64
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"main/decimation") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetString(&d, &config, L"1 / 64");
*/
// Connect to the physical device
if ((res = AARTSAAPI_ConnectDevice(&d)) == AARTSAAPI_OK)
{
for (int n = 0; n < 50000; n++) {
// Start the receiver
if (AARTSAAPI_StartDevice(&d) == AARTSAAPI_OK)
{
// Receive some spectra
std::cout << "---------[" << n << "]" << "\n";
streamSpectra(d);
// Stop the receiver
AARTSAAPI_StopDevice(&d);
Sleep(20);
}
}
// Release the hardware
AARTSAAPI_DisconnectDevice(&d);
}
else
std::wcerr << "AARTSAAPI_ConnectDevice failed : " << std::hex << res << std::endl;
}
// Close the device handle
AARTSAAPI_CloseDevice(&h, &d);
}
else
std::wcerr << "AARTSAAPI_OpenDevice failed : " << std::hex << res << std::endl;
}
else
std::wcerr << "AARTSAAPI_EnumDevice failed : " << std::hex << res << std::endl;
}
else
std::wcerr << "AARTSAAPI_RescanDevices failed : " << std::hex << res << std::endl;
// Close the library handle
AARTSAAPI_Close(&h);
}
else
std::wcerr << "AARTSAAPI_Open failed : " << std::hex << res << std::endl;
// Shutdown library, release resources
AARTSAAPI_Shutdown();
}
else
std::wcerr << "AARTSAAPI_Init failed : " << std::hex << res << std::endl;
Also the following configuration leads to a Access Violation Reading exception:
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"main/startfreq") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetFloat(&d, &config, 5e9);
if (AARTSAAPI_ConfigFind(&d, &root, &config, L"main/stopfreq") == AARTSAAPI_OK)
AARTSAAPI_ConfigSetFloat(&d, &config, 6e9);
This is fixed from build 10056 on. Thanks for the report!
My pleasure , thank you very much for confirming and fixing.
Sorry, It's probably my fault, but from where can I download this build? I am totally unable to find it out, and just see the RTSA-Suite PRO - Stable (Windows) 2.1.1.9959 at the download page.
Please send us a mail to get a link for the latest BETA.
done, sent to [email protected]
vielen dank für die gute arbeit !!
Good morning, got the link by email but sadly seems I am not allowed to download it :
