Measurement Functions
Operation States
Stress Force State
In the stress force state, the 4155B/4156B outputs stress. The output switches are off
for units that do not have entries in the CHANNELS table of the STRESS:
CHANNEL DEFINITION screen.
Standby State
In the standby state, the 4155B/4156B does not perform measurements or stress
force, but it outputs dc bias and/or pulses using the measurement units defined as the
standby channel. Following settings keep the same conditions as the previous state:
• output switch of each unit
• output impedance of PGUs
• switching condition of the 16440A selector
• resistance selection of the 16441A R-Box
Changing among Operation States
Figure 3-3 shows how to change among the operation states.
• From measurement/stress states to idle state:
If you perform measurements or force stress from the idle state, then the
4155B/4156B returns to the idle state after one of the following conditions
occurs:
• Measurement is finished.
• Fixture lid is opened while an SMU is outputting more than ±40 V.
• Stress is finished.
• Stop front-panel key is pressed.
