Syntax

ViStatus _VI_FUNC hpe5250a_cmdReal(ViSession vi, ViString cmd_str,

 

ViReal64 value);

 

Parameters

vi

Instrument handle returned from hpe5250a_init( ).

 

cmd_str

Instrument command (cannot exceed 256 bytes in length).

hpe5250a_cmdReal64Arr_Q

This function passes the cmd_str string to the instrument. This command expects a response that is a definite arbitrary block of 64 bit reals. You specify the cmd_str and size parameters, and get result[ ] and count.

Syntax

ViStatus _VI_FUNC hpe5250a_cmdReal64Arr_Q(ViSession vi, ViString cmd_str,

 

ViInt32 size, ViReal64 _VI_FAR result[ ], ViPInt32 count);

Parameters

vi

Instrument handle returned from hpe5250a_init( ).

 

cmd_str

Instrument command (cannot exceed 256 bytes in length).

 

size

Size of result[ ] (number of items in the array).
