User’s Manual
WARNING Even with the voltage protection limit set to the lowest value (20V),
NEVER touch anything connected to the terminals of the SourceM
-
eter when the OUTPUT is ON. Always assume that a hazardous
voltage (>30V
rms) is present when the OUTPUT is ON.
To prevent damage to DUT (devices-under-test) or external cir-
cuitry, DO NOT program the V-Source to levels that exceed the
voltage protection limit.
Set delay
NOTE For the Model 2430 Pulse Mode, source delay is not used. Therefore, the fol-
lowing commands for source delay are ignored.
DELay <n>
:SOURce[1]:DELay <n> Manually set source delay
Parameters <n> = 0 to 999.9999 Specify delay in seconds
MINimum 0 seconds
MAXimum 999.9999 seconds
DEFault 0 seconds
Query :DELay? Query delay
:DELay? DEFault Query *RST default delay
:DELay? MINimum Query lowest allowable delay
:DELay? MAXimum Query highest allowable delay
Description This command is used to manually set a delay (settling time) for the
source. After the programmed source is turned on, this delay occurs
to allow the source level to settle before a measurement is taken.
Note that this delay is the same for both the I-Source and V-Source.
Do not confuse this source delay with the trigger delay. The source
delay is part of the device action (SDM cycle) while the trigger delay
occurs before the device action. See
Section 11, “Trigger models,”
for more information.
Auto delay can instead be used to automatically set the source
delay. (See next command.)
AUTO <b>
:SOURce[1]:DELay:AUTO <b> Enable/disable auto delay for source
Parameters <b> = 0 or OFF Disable auto delay
1 or ON Enable auto delay
Query :AUTO? Query state of auto delay
Description This command is used to enable or disable auto delay. When
enabled, the instrument will automatically select a delay period that
is appropriate for the present source/measure setup configuration
(Table 3-4). *RST and SYST:PRES default is ON.
