Function Details

Bias Hold Function

This function is used to keep source output after measurement. Source modules

apply the specified bias between measurements in a quick test or application test

that defines some classic test setups, or a repeat measurement. And the source

modules change the output value and the unused modules are disconnected when the

next measurement is started.

Output channels

and output value

If the bias hold function is OFF, the channel stops the output immediately after

measurement.

If the function is ON, the channel continues the output as shown below.

I/V Sweep measurement:.

• VAR1 and VAR1’ output channels: Sweep start or stop value

• VAR2 output channel: Sweep stop value

• CONST output channels: Output value

• SMU pulse output channels: Base value

C-V Sweep measurement:

• Bias sweep output channel: Sweep start or stop value

• CONST output channels: Output value

I/V-t Sampling measurement:

• Constant source output channels: Base or source value

SPGU output:

• SPGU keeps the output as shown in Table 4-6.

Period of bias hold • From the end of a measurement to the end of a single measurement

• From the end of a measurement to the start of the next measurement during a

quick test, application test, or repeat measurement

Reset of source

output

The source output is reset after a quick test, application test, repeat measurement, or

single measurement. The SMU is set to 0 V output and 0.1 mA compliance. The

MFCMU is set to 0 V DC bias and 0 V oscillator level.
