Remote Mode Functions
Measurement Modes
This operation is repeated until when the total sampling time runs over Bias hold
time + Sampling interval × number of samples. The sampling measurement will
be stopped even if the number of measurement result data is less than number.
9. After the sampling measurement, the CMU forces the base or bias value
specified by the MDCV command.
The source channel set by the DV or DI command continues the source output.
For 0 V output, enter the DZ command that is used to memorize the present
settings of the channel and change the output to 0 V.
The index data (max. 10001) and the time data returned with the measurement data
is given by the following formula. It depends on the measurement ranging mode set
by the RC command. However, long measurement or busy status may cause
unexpected time and index data.
For the fixed range mode
time = Bias hold time + index × Sampling interval
For the auto range mode
time = Beginning time of one point measurement - t
Where, t is the time of the sampling measurement time origin, and is the time
when the output value is changed from base to bias.
NOTE The MTDCV command sets the bias hold time, sampling interval, number of
samples, and base hold time.
The MSC command sets the automatic abort function.
The MDCV command sets the DC bias output and the output after measurement.
The FC command sets the AC signal frequency.
The ACV command specifies the oscillator level, and applies the AC signal.
If the SCUU (SMU CMU Unify Unit) is connected to the CMU and two
MP/HRSMU modules correctly, the source module is automatically selected by the
DC bias setting. The CMU is selected if it is ±25 V or less (setting resolution: 0.001
V), or the SMU is selected if it is greater than ±25 V (setting resolution: 0.005 V).
To Stop Output An automatic abort function is available. Refer to “Automatic Abort Function” on
page 2-46.
