Source Measurement Function
5.3.1
Source Range
When the optimal range for voltage source is selected (the
FIT
key goes ON) in the DC source mode, the
range is determined according to the following list:
5.3.2
Suspend Function
The 4601 can select from three output statuses; Standby (output relay OFF), Suspend HiZ (output relay
ON and high resistance), and Suspend LoZ (output relay ON and low resistance).
The suspend function is available in both the DC source mode and the sweep source mode.
Using this function can reduce unnecessary relay ON/OFF action of the output unit, which reduces dete-
rioration of the throughput due to relay operation time and improve the life of the relay.
Therefore, setting in the Suspend status is recommended whenever turning OFF the output to change the
measurement condition.
The following figure shows a conceptual diagram of output status.
