Command Reference
AIT
2: Power line cycle (PLC) mode
3: Measurement time mode. Not available for the high-resolution ADC.
N : Coefficient used to define the integration time or the number of
averaging samples, integer expression, for mode=0, 1, and 2. Or the
actual measurement time, numeric expression, for mode=3. See Table
4-21.
The pulsed-measurement ADC (type=2) is available for the all measurement
channels used for the pulsed spot, pulsed sweep, multi channel pulsed spot, multi
channel pulsed sweep, or staircase sweep with pulsed bias measurement.
Table 4-21 Available Parameter Values
type mode N
00Value that defines the number of averaging samples given by the
following formula. N=1 to 1023. Default setting is 1.
Number of averaging samples = N × initial averaging
where initial averaging is the number of averaging samples
automatically set by Agilent B1500 and you cannot change.
1 Number of averaging samples. N=1 to 1023. Default setting is 1.
2 Value that defines the number of averaging samples given by the
following formula. N=1 to 100. Default setting is 1.
Number of averaging samples = N × 128
The Agilent B1500 gets 128 samples in a power line cycle,
repeats this for the times you specify, and performs averaging to
get the measurement data.
3 Actual measurement time, in seconds. N=2 μs to 20 ms, 2 μs
resolution. Default setting is 2 μs.
For HR/MP/HPSMU, it performs the operation of mode=1. Then
the number of averaging samples is automatically set to the
following value.
Number of averaging samples = N / Tm
Tm: Required time for one sample measurement
If N / Tm < 1, Number of averaging samples =1.
