PostDataDouble

This command posts double-precision floating point data from memory into the Clarius Analyze sheet.
Usage
int PostDataDouble(char *ColName, double *array);
ColName
array
Pulsers
4225-PMU
Pulse mode
Standard and Segment Arb
Details
You can use the PostDataDouble command to post double-precision floating point data into the
Clarius Analyze sheet. Up to 65,535 points (rows) of data can be posted into the Analyze sheet.
These commands are used after one measurement point is finished and a data value is assigned to
the corresponding output variable.
If you do not need to analyze or manipulate the test data before posting it into the Analyze sheet, you
can use smeasxrt for CVUs or pulse_measrt for PMUs, which retrieves all the test data in
pseudo real-time and automatically posts it into the Analyze sheet.
Example
// Code to configure the PMU test here
// Start the test (no analysis)
pulse_exec(0);
// While loop (continues while test is still running), with delay
// (30 ms)
while(pulse_exec_status(&elapsedt) == 1)
{
Sleep(30);
}
// Retrieve V and I data (no timestamp or status)
status = pulse_fetch(PMU1, 1, 0, 100, Vmeas, Imeas, NULL, NULL);
// Separate V & I measurements for high (amplitude) and
// low (base)
for (i = 0; i<100; i++)
{
VmeasHi_sheet[i] = Vmeas[2*i];
ImeasHi_sheet[i] = Imeas[2*i];
VmeasLo_sheet[i] = Vmeas[2*i+1];
ImeasLo_sheet[i] = Imeas[2*i+1];
PostDataDouble("DrainVmeas", VmeasHi_sheet[i]);
PostDataDouble("DrainImeas", ImeasHi_sheet[i]);
}
