Table 1-10 Status for Measurement Data
A Explanation
N No status error occurred.
T Another channel reached its compliance setting.
C This channel reached its compliance setting.
V Measurement data is over the measurement range. Or the sweep measurement
was aborted by the automatic stop function or power compliance. D will be
199.999E+99 (no meaning).
X One or more channels are oscillating. Or source output did not settle before
measurement.
a
a. Make the wait time or delay time longer. Or make the current compliance larger. For
pulsed measurement, make the pulse width longer, or make the pulse base value
closer to the pulse peak value. For current output by limited auto ranging, make the
output range lower.
F SMU is in the force saturation condition.
G For linear or binary search measurement, the target value was not found within
the search range. Returns the source output value.
For quasi-pulsed spot measurement, the detection time was over the limit (3 s for
Short mode, 12 s for Long mode).
b
b. Make the current compliance or start voltage larger. Or set the detection interval to
Long. If this status occurs with the Long mode, perform the spot measurement.
S For linear or binary search measurement, the search measurement was stopped.
Returns the source output value. See status of Data_sense.
For quasi-pulsed spot measurement, output slew rate was too slow to perform the
settling detection.
c
Or quasi-pulsed source channel reached the current
compliance before the source output voltage changed 10 V from the start
voltage.
d
c. Make the current compliance larger. Or set the detection interval to Long. If this sta-
tus occurs with the Long mode, perform the spot measurement or pulsed spot mea-
surement.
d. Perform the pulsed spot measurement or spot measurement.
U CMU is in the NULL loop unbalance condition.
D CMU is in the IV amplifier saturation condition.
