Sampling Measurements
Measurement Functions
HOLD TIME Hold time. This is the time from starting source output
to first trigger. If this value is 0, first @TIME value is 0.
• Allowable range when
INITIAL INTERVAL ≥ 2 ms:
0 to 655.35 s with 100 μs resolution.
• Allowable range when
INITIAL INTERVAL < 2 ms:
− 30 ms to 655.35 s with 100 μs resolution.
Table 3-1 Effective Parameter Values
a
Number of units (SMUs or VMUs) used for measurements.
b
If voltage source SMU is connected to R-BOX, only this SMU can be used for the
measurement.
c
Maximum 8 units if the 41501 is used (6 SMUs and 2 VMUs). If multiple
measurement units are used, total measurement time will be more than the sum of
the measurement time by all units.
d
If compliance value is more than the measurement range, range change when
starting measurement makes long measurement time. Also if ranging mode is set
to AUTO or LIMITED, range changing makes long measurement time.
e
Integration time is an element of the measurement time. If automatic measurement
data compensation is executed, the measurement time will be more than two times
the integration time.
