Function Details

SMU Ranging Mode

Agilent B1500 provides the following operation modes for the measurement range

and the output range. The ranging mode must be set for each channel.

• “Auto Ranging”

• “Limited Auto Ranging”

• “Fixed Range”

• “Compliance Range”

• “Enhanced Auto Ranging for Current Measurement”

To Set Ranging Mode

The following points must be noted when setting the ranging mode.

For measurement

channels

• If you do not specify the ranging mode, the auto ranging mode is set

automatically.

• For the channels that perform Vf/Vm (voltage force and voltage measurement)

or If/Im (current force and current measurement), the measurement range is

always the same as the output range.

• For measurement with pulse output, the measurement channel uses the

compliance range or the specified fixed range. The channel cannot perform the

auto ranging operation or the limited auto ranging operation.

• For the SMU connected to the atto sense/switch unit (ASU), the 10 pA range is

the minimum for the auto ranging operation. To use the 1 pA range, select the 1

pA limited auto ranging mode or the 1 pA fixed range mode.

For output

channels

• The auto ranging mode and the limited auto ranging mode are available for the

output channels.

• When the voltage output range or the voltage compliance range is changed, the

channel forces 0 V at that moment.
