Function Details
Standby Function
Standby Function
This function forces the specified DC bias outputs (standby outputs) before starting
or after stopping a measurement.
Standby Channels
Standby channels are source monitor units (SMU) that force the standby output.
Standby channels maintain the specified DC bias output when the standby mode is
ON and in the non-measurement state.
Standby channel cannot be set for CMU, GNDU, and HRSMU connected to the atto
sense and switch
unit (ASU) which makes the path to the AUX port.
See “Standby Channel Definition” on page 4-50 to define the standby channels and
set the standby mode.
Standby State
Standby state is the state before starting or after stopping a measurement, in which
only the standby channels perform DC bias outputs. The other channels will be in
the idle state, which is 0 V output, 100 μA compliance, SMU filter OFF, and series
resistor OFF. When the standby mode is OFF and in the non-measurement state, all
channels will be in the idle state.
When B1500A is in the standby state, the measurement trigge
r stops the standby
state, so the standby channels stop the standby output and the measurement channels
perform a measurement (measurement state). After the measurement, the standby
channels start the standby output (standby state). During this series of operations,
the state is never changed to the idle state. See Figure 7-20 for an example
operation.
If the bias hold function is enabled for the s
tandby channel, after the
measurement,
the channel forces the bias output set by the bias hold function. After the bias hold
period, the channel starts the standby output. During this series of operations, the
state is never changed to the idle state.
