6-12 External Triggering (Model 2306-VS Only)
4. Channel with BOTH AUTO has STEP:VOLT ON or STEP:READ is not AUTO with
BOTHON parameter for BOTHTRIGEXT command. Error message: “+228, Both auto
has step volt or step read conflict”
5. Channel one and two have different values for STEP:POINts with ONEON or TWOON
paramete
rs. Error message: “+229, Channel one and two have step points conflict”
6. Channel being enabled has BOTH set to NONE with ONEON or TWOON parameters.
Error
message: “+230, Parameter with both set to none conflict”
7. Channel not being enabled has BOTH not set to NONE with ONEON or TWOON
paramete
rs. Error message: “+231, Parameter with both not set to none conflict”
8. BOTH is set to VOLT and either channel has
STEP:VOLT set to OFF or STEP:READ
not set to NONE with ONEON or TWOON parameters. Error message: “+232, Both volt
with a step volt or read conflict”
9. BOTH is set to AUTO and either channel has
STEP:VOLT set to ON or STEP:READ
not set to AUTO with ONEON or TWOON parameters. Error message: “+233, Both
auto with a step volt or read conflict”
10. Either selecting trigger external enable to be on while trigge
r continuous is enabled or
selecting trigger continuous while trigger external is enabled. Error message: “+236,
Trigger continuous and external enable conflict”
11. Enabling trigger external while long integration is the selected function on the channel.
Error
message: “+237, Trigger external enable long integration conflict”
Other setting conflicts that may be seen while enabled:
1. Trying to change a trigger external setting while
a channel's trigger external enable is
ON. Error message: “+234, Trigger external setting channel enabled conflict”
2. Trying to change a system parameter that would interfere with a channel having its
trig
ger external enable ON. Error message: “+235, Trigger external enabled system

External trigger sequences
The discussion below highlights typical external trigger sequences for various operating
modes. For any of these configurations to be executed on the Model 2306-VS, the
TRIG:EXT:ENAB command state must be ON. However, this must be the last configuration
command sent to the power supply. Prior to this command, send all of the other commands
needed to configure the supply for all other desired functionality. Since TRIG:EXT:ENAB must
be ON for all of these configurations, it is not listed in the table but, rather be implied. For BOTH
configurations, the TRIG:EXT:ENAB command is replaced with the BOTHTRIGEXT
command.
The following list of abbreviations
apply to the list of characteristics and Table 6-2 that
follows:
• BOTH implies the TRIG:EXT:BOTH setting.
• VOLT implies the TRIG:EXT:STEP:VOLT setting.
• READ implies the TRIG:EXT:STEP:READ setting.
