Command Reference
Command Reference
TTV
The TTV 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 voltage 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 TTV 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 4-2 on
page 4-10.
If you do not specify the range parameter for current output channels,
the channel uses the minimum range that covers the compliance value.
The range parameter is meaningless for voltage output channels. The
measurement ranging type is always same as the output ranging type.
Remarks To read the time data with the best resolution (100 μs), the timer must be cleared
every
100 sec or less for the FMT1, 2, or 5 data output format, or
every 1000 sec or less for the FMT 11, 12, 15, 21, 22, or 25 data output format.
