Data Output Format
Sampling,
C-t sampling
Available for the 8 bytes binary data format (FMT13 or FMT14).
Block1 [Block2] . . . . <terminator>
Block1 is the block of the data measured at the first sampling point. Block2 is the
block of the data measured at the second sampling point. where Block consists of
the following data.
[Sampling_no] Data1 [Data2] . . . .
Sampling_no is the sampling point index, and is returned by entering the FMT
command with mode<>0. This value depends on the sampling interval setting and
the measurement time. If the measurement time is shorter than the sampling
interval, Sampling_no will be N of BlockN (N: 1, 2, 3 . . . ).
DataN (N: integer) is the data measured by one unit. The order of Data is specified
by the MM command. Sampling_no and Data values can be discarded when the
range changing is occurred while the measurement with auto or limited auto
ranging.
If the measurement time is longer than the sampling interval, Sampling_no is not N
of BlockN. For example, if the measurement time is longer than the sampling
interval and shorter than twice the sampling interval, then the Sampling_no is 2 for
Block1, and 4 for Block2. In general, the measurement time depends on the
measurement value and the A/D converter settings.
For the C-t sampling, DataN will be Para1 Para2.
Para1 and Para2 are R (Ω) and X (Ω), or G (S) and B (S) respectively. They will be
automatically selected by the B1500, and will be a couple without data overflow.
Quasi-static CV Block1 [Block2] . . . . <terminator>
Block1 is the block of the data measured at the first sweep point.
Block2 is the block of the data measured at the second sweep point.
where Block consists of the following data:
[DataL] DataC
[Source_data]
DataL is the leakage current measurement data. DataC is the capacitance
measurement data. Source_data is the sweep source output value. DataL and
Source_data are sent if the data output is enabled by the QSL or FMT command.
