Standby Function
Standby Function
The 4155B/4156B can force standby outputs before starting or after stopping a
measurement or stress. You can select dc or pulse bias for the standby output.
Standby Channels
Standby channels are the measurement units which force the standby output. SMUs,
VSUs, and PGUs can be used for the standby channel. VMUs and GNDU are not
available.
To define a measurement unit as a standby channnel, move the field pointer to the
STBY field on the CHANNELS: CHANNEL DEFINITION screen, and select the
STANDBY ON softkey.
You cannot use the standby channel as the stress channel. The standby channels
keep the standby output when the 4155B/4156B is in the stress force state.
Standby State
Before starting or after stopping a measurement or stress, if only the standby
channels perform dc or pulse outputs, the 4155B/4156B is in the standby operation
state.
To start the standby output, press Standby front-panel key. Then the indicator is lit.
However, if no units are defined as the standby channel, the 4155B/4156B cannot be
in the standby state.
To stop the standby output, press Standby front-panel key. The indicator is off.
When the 4155B/4156B is in the standby state, you can change setting parameters
for non-standby channels without changing the state. But if you modify the settings
for the standby channels, the 4155B/4156B changes from the standby state to the
idle state.
