image\head10.gif Operation             Queries the self-test (self-diagnosis) results. (*TST?)

 

image\head10.gif Format                 

(VB.NET)

Dim Adr, Srlen, Ret As Integer

Dim Srbuf As String

Ret = GpQtst(Adr, Srlen, Srbuf)

 

(C)

DWORD Adr, Srlen, Ret;

char * Srbuf;

Ret = GpQtst(Adr, &Srlen, Srbuf);

 

(C#)

uint Adr, Srlen, Ret;

StringBuilder Srbuf = new StringBuilder(xxxx); /* (xxxx specifies the maximum amount of data.) */

Ret = gpib.Qtst(Adr, out Srlen, Srbuf);

 

(Python)

Adr, Srlen, Ret = ctypes.c_ulong(), ctypes.c_ulong(), ctypes.c_ulong()

Srbuf = ctypes.create_string_buffer(xxxx) #(xxxx specifies the maximum amount of data.)

Ret.value = GpibPy.GpQtst(Adr, ctypes.byref(Srlen), Srbuf)

 

image\head10.gif Mode                   Master mode only
