the string in cmd_str followed by a space and then the real in value. Note that either
an Real32 or 64 can be passed as the Real32 will be promoted.
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).
value Parameter for command. -1E+300 to 1E+300.
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).
1 to 2147483647.
result[ ] Response from instrument.
