Command Reference
Command Reference
TTI
The TTI command performs the high speed spot measurement, and returns the
measurement data and the time data for the time from when the timer is cleared until
the measurement is started. The command starts a current measurement regardless
of the SMU operation mode, trigger mode (TM command), and measurement mode
(MM command).
This command is effective for ASCII data output format. Refer to “FMT” on page
4-59 .
Execution
Conditions
CN command has been executed for the specified channel.
Syntax
TTI chnum [, range ]
Parameters chnum : Measurement channel number. The value must be slot number where
the module has been installed. Integer expression. 1 to 8 (1 and 5 are
not available for HPSMU). See
Table 4-1 on page 4-9 .
range : Measurement range or ranging type. Integer expression. If you select
the fixed range, the instrument performs measurement by using the
specified range. For the auto or limited auto ranging, the measurement
range will be set to the minimum range that covers the measured
values. However, the instrument never uses the range less than the
specified range for the limited auto ranging. See
Table 4-3 on
page 4-11 .
If you do not specify the range parameter for voltage output channels,
the channel uses the minimum range that covers the compliance value.
The range parameter is meaningless for current output channels. The
measurement ranging type is always same as the output ranging type.
NOTE
To use 1 pA range (only for E5270B)
The measurement channel connected to the ASU (Atto Sense and Switch Unit)
supports the 1 pA range. To use the 1 pA range, set the 1 pA fixed range or the 1 pA
limited auto ranging.
To enable the 1 pA range for the auto ranging mode, execute the SAR command.
