Data Output Format
Data Format
The data output format depends on the measurement mode as shown below.
High speed spot Data <terminator> (by TI, TV, TMACV, or TMDCV command)
Time Data <terminator> (by TTI or TTV command)
Para1 Para2 <terminator> (by TIV / TC command)
Time Para1 Para2 <terminator> (by TTIV / TTC command)
Data is the value measured by the channel you specify in the command. Time is the
time from timer reset to the start of measurement. Para1 and Para2 are current (A)
and voltage (V) respectively measured by the SMU; or R (Ω) and X (Ω); or G (S)
and B (S) respectively measured by the CMU. The CMU measurement data will be
automatically selected by the B1500, and will be a couple without data overflow.
Time is available for the 8 bytes binary data format (FMT13 or FMT14) and not
available for the 4 bytes binary data format (FMT3 or FMT4)
TDI, TDV, TSQ,
TACV, TDCV
command
Available for the 8 bytes binary data format (FMT13 or FMT14).
Time <terminator>
Time is the time from timer reset to the start of output.
Spot,
Multi channel
pulsed spot
Data1 [Data2] . . . . <terminator>
DataN (N: integer) is the value measured by a channel. The order of Data is defined
by the MM command.
Pulsed spot,
Quasi-pulsed spot,
Spot C,
Pulsed spot C
Data <terminator>
Data is the value measured by the channel you specify by using the MM command.
For the spot C, Data will be Para1 Para2 [Osc_level Dc_bias].
For the pulsed spot C, Data 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.
And Osc_level and Dc_bias are the monitor values of the oscillator level (AC signal
level) and the DC bias respectively. They are sent if the data output is enabled by the
LMN command.
