Remote Mode Functions

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.
