Operation States
Operation States
The 4155B/4156B has the following four operation states.
• “Idle State”
• “Measurement State”
• “Stress Force State”
• “Standby State”
Idle State
In the idle state, the 4155B/4156B is not doing anything: no measurements, forcing
current or voltage, forcing stress.
An 4155B/4156B is in the idle state after applying power. In this state, output
switches of all the measurement units are on, and all of the units output 0 V. In this
state, you can modify any setting items on the setup screens.
The following are the conditions of each unit and accessories in idle state.
SMU 0 V output at 20 V range, and 100

Measurement State
In the measurement state, an 4155B/4156B performs sampling or sweep
measurements. The output switches are off for units that do
not have entries in the
CHANNELS table of the CHANNELS: CHANNEL DEFINITION screen.
