Function Details
Voltage Source (B2985B/B2987B)
Table 5-2
Output-Off State
This setting is not applied to the output-off process triggered by the emergency
condition such as the interlock open and over temperature protection. In these
situations, the output voltage is immediately set to 0 V and the output switch is
set to off.
Current Limiting Resistor
The voltage source has internal 20 M
current limiting resistor at the output end.
Connecting it in series can limit the output current. For example, if the voltage
source forces 100 V, this resistor limits maximum 5
A output current.
You can control the connection of this resistor using the Resistive Limit State field.
See
“Output Connection Dialog Box” on page 173
.
Triggered Voltage Source
During the voltage source applies a constant voltage, if a trigger signal is
received, it changes the output to the pre-specified value. The value is specified by
the Triggered Voltage Source field. See
“Range Setup Sub-panel” on page 151
