Parallel Measurement Function
The following measurement modes allow to use the multiple measurement channels.
• Spot measurement (MM 1,chnum,chnum, . . . ,chnum)
• Staircase sweep measurement (MM 2,chnum,chnum, . . . ,chnum)
• Sampling measurement (MM 10,chnum,chnum, . . . ,chnum)
• Multi channel sweep measurement (MM 16,chnum,chnum, . . . ,chnum)
For the spot measurement, staircase sweep measurement, and sampling
measurement, executing the PAD1 command before starting measurement enables
the parallel measurement (simultaneous measurement).
For the multi channel sweep measurement and the sampling measurement of the
sampling interval < 2 ms, the parallel measurement is always effective without the
PAD1 command.
Measurement is performed as shown below.
1. Measurement channels that satisfy the following required conditions start
measurement simultaneously (parallel measurement).
2. After the parallel measurement, the other channels perform measurement in the
order defined in the MM command.
Required Conditions
The following conditions must be satisfied for the measurement channels to perform
the parallel measurements.
• Use the high speed A/D converter
AAD chnum,0 command
• Use the fixed ranging for the measurement
RI chnum,range command (for current measurement)
RV chnum,range command (for voltage measurement)
Enter the negative value for range to use the fixed ranging.
