4601 I-V Meter Operation Manual
5.3.2 Suspend Function
5-19
1. Operation
1. Standby status
Pressing
STANDBY
sets the output status to Standby.
The 4601 is securely isolated from the DUT.
2. HiZ Suspended status
Pressing
SUSPEND
sets the output status to Suspend. The
SUSPEND
key goes ON.
This is the status for the LoZ/HiZ switch OFF with the OPR/STBY relay ON.
Vsus voltage (0 V) is output in the Suspend status.
As the output status is high resistance, it rarely affects the DUT.
3. LoZ Suspended status
LoZ Suspend status is the same as HiZ Suspend status except that the output status is low resis-
tance.
This status is effective in setting the DUT to low impedance status when the output is OFF.
The output response speed is faster because the limit value does not change in the Operate status.
4. Current limit in Suspend
The output in the Suspend status is always 0 V. The current limit is set to the values shown in
Figure 5-9, "Conceptual Diagram of Output Status."
2. Setting Suspend conditions
Setting the output resistance in the Suspend status
Select
A) SOURCE
3) Suspend Z
on the menu screen.
High Impedance: High resistance output status
The current limit values are set to 30 digits in the setting range.
Low Impedance:
Low resistance output status
The setting current limit values are applied.
