Example: Positive
Current Compliance
This program checks the MEASURED current output from the DAC
channel being tested. If the DC SOURCE voltage is
≥
13.0V when the
output current drops to 90% of maximum current, the program generates a
"Test PASSED" indication. If the DC SOURCE voltage is < 13.0V when
the output current drops to 90% of maximum current, the program generates
a "Test FAILED" indication.
if (value >= 15)
pass = "PASSED";
else
pass = "FAILED";
printf("\n\nMaximum channel %u output = %.1f volts", chan, value);
printf("\nTest %s for channel %u\n", pass, chan);
}
iclose (id); /* Close instrument session */
}
