* The END voltage becomes the voltage setting whenever external triggering is disabled, which happens (1) by commands to disable external triggering,
(2) if the heat sink or power supply temperature is excessive, or (3) if the VPT or current limit is tripped for either channel.

Command notes

TRIGger[1]:EXTernal:BOTH <name>
TRIGger2:EXTernal:BOTH <name>
These commands select which channel(s) to control. If NONE is selected, the channel is
configured to only control a single channel and not both. For this setting, use TRIG:EXT:ENAB
to control whether trigger external functionality is ON or OFF. If VOLT is selected, both
channels are controlled with the channel's trigger in pulse to voltage step only (no measurements
taken). If AUTO is selected, both channels are taking AUTO measurements and doing no
voltage stepping. For VOLT or AUTO settings, use the BOTHTRIGEXT command to enable or
disable the trigger external functionality.
If a channel has BOTH set to AUTO and the other channel set to VOLT, the channel set to
BOTH VOLT will step voltages as long as trigger in pulses are detected even though the channel
set to BOTH AUTO has stopped measuring. The BOTH AUTO channel will require an INIT
command to resume measuring after the programmed number of STEP:POINts, but the BOTH
VOLT channel will not require an INIT command to resume measuring under these conditions.

Description
TRIGger subsystem for Channel #2 (charger channel):
Path for external trigger control under TRIGger2 subsystem.
Select channel both control type (NONE, VOLT, or AUTO).
Path for specifying the trigger in & out pulse edges.
Select trigger in pulse polarity (RISING or FALLING).
Select trigger out pulse polarity (RISING or FALLING).
Enable (ON) or disable (OFF) external trigger feature.
Initialize channel to take another set of measurements.
Set voltage step parameters; step # (1-20), voltage (0-15),
delay (0-5).
Query voltage and delay for a given step number.
Query next step to be completed when trigger in pulse
detected.
Enable (ON) or disable (OFF) voltage step feature.
Set voltage when external trigger turned OFF (0-15).*
Set reading/measurement mode (NONE, SYNC or AUTO). AUTO
Set # of measurements and/or voltage steps (1-20).
Enable (ON) or disable (OFF) Voltage Protection Tripping. ON
Enable/disable external trigger configurations: ONEON,
ONEOFF, TWOON, TWOOFF, BOTHON or BOTHOFF.
