6-8 External Triggering (Model 2306-VS Only)
Once a channel is enabled, a settings conflict error message will occur when:
1.
2.
TRIGger[1]:EXTernal:ENABle:INIT
TRIGger2:EXTernal:ENABle:INIT
These commands initialize the channel to take another set of STEP:POINts measurements.
For configurations taking measurements, the measurements will stop after taking the POINts
number of measurements. This allows time for sending FETCh:ARRay? query command to get
the data from the buffer before being overwritten by another measurement. However, if voltage
stepping only and not taking measurements, the list will cycle around to step 1 and continue
stepping voltages and not stop. After querying for measurements, send this command to
initialize the channel to resume detecting and responding to trigger in pulses on the channel.
This command must be sent while the trigger enable is set to ON. If not sent, doing a
FETCh:ARRay? query will result in the same data being returned. Send the INIT command if:
1.
2.
3.
After processing the INIT command and ready to detect trigger in pulses again, the trigger
out signal will pulse accordingly to indicate it is ready for the next trigger in. This command will
generate a settings conflict error message if the INIT command is sent when the channel's trigger
external functionality is disabled, or if the INIT command is being requested while the channel's
trigger external BOTH setting is NONE and the other channel's trigger external BOTH setting
is AUTO or VOLT. Error message: "+224, Trigger external enable init conflict."

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."
Error +234 will be generated if BOTH = VOLT or AUTO for channel having
TRIG:EXT:ENAB OFF command or the other channel has BOTH set to VOLT/AUTO
with external trigger enabled.
Trying to change a system parameter that would interfere with a channel's having its
trigger external enable ON. Error message: "+235, Trigger external enabled system
setting conflict." Error +235 will be generated if external trigger is enabled and these
commands are sent: *TRG, *TRG1, *TRG2, READ1?, READ2?, MEAS?,
BOTHREAD?, BOTHFETCh?, and BOTHTRG.
A channel is taking AUTO measurements (READ = AUTO).
A channel is taking measurements and volt stepping (READ = AUTO or SYNC; VOLT
ON).
A channel is taking AUTO measurements on both channels (BOTH = AUTO).
Applies to battery channel (#1)
Applies to charger channel (#2)
