Keithley 2302 User Manual

External Triggering (Model 2306-VS Only) 6-11
features, the setting is ignored, and VPT operates normally. If set to OFF (disabled), the unit
does not monitor for a VPT condition while using the TRIGger:EXTernal features.
If the delta step size (difference between two v
oltage steps) is greater or equal to the
SOUR:VOLT:PROT setting (*RST default is 8V) then, a VPT condition may occur. If a VPT
condition occurs while trigger external features are enabled, the trigger external feature is
disabled automatically, and the output is turned off regardless of the channel experiencing
the VPT.
:BOTHTRIGEXT <name>
Use this command to enable or disable external trigger BOTH configurations on channel 1,
channel 2 or both with a single command. You must use this command to use the BOTH feature.
Use TRIG:EXT:ENAB for individual channel control. Channel 1 is processed first then,
channel 2.
Parameters:
ONEON - enable BOTH configuration on channel 1.
TWOON - enable BOTH configuration on channel 2.
BOTHON - enable BOTH configuration on channel 1 & 2.
ONEOFF - disable BOTH configuration on channel 1.
TWOOFF - disable BOTH configuration on channel 2.
BOTHOFF - disable BOTH configuration on channel 1 & 2
When enabled, a channel will automatically turn the output ON and turn the display OFF.
Whe
n disabled, the output goes OFF and display goes back ON. If the parameter is ONEON,
TWOON or BOTHON, enable for each channel (TRIG:EXT:ENAB or TRIG2:EXT:ENAB)
goes ON. If the parameter is ONEOFF, TWOOFF or BOTHOFF, enable for each channel goes
OFF. Therefore, after sending this command, if a query for TRIG:EXT:ENAB or
TRIG2:EXT:ENAB is sent, the response will be either ON or OFF depending on the parameter
sent. The trigger external enable setting for both channels is changed by this command.
Settings Conflicts that may occur when sending one of the ON parameters (ONEON,
TW
OON or BOTHON):

ile a channel already has trigger external enable set to ON. Error message:

2. BOTH for either channel is set to NONE when BOTHON is parameter with
BO
THTRIGEXT command. Error message: “+226, Bothon parameter with a channel
both conflict”
3. Channel with BOTH VOLT has STEP:VOLT OFF or STEP:READ is not NONE with
BO
THON parameter for BOTHTRIGEXT command. Error message: “+227, Both volt
has step volt or step read conflict”
