2.5 Tran Test
Tran test can be switched back and forth between two currents or voltages set by the load. This
function can be used to test the dynamic characteristics of the power source
. Moreover, the Tran test is
divided into three modes: continuous mode, pulse mode and trigger mode, as described below:
Continuous mode: in this mode, the load can continuously switch between level A and level B after
the test is started.
Pulse mode: in this mode, after the test is started, the load will switch from level A to level B every
time it receives a trigger signal, and then switch back to level A after maintaining level B pulse
width.
Trigger mode: in this mode, after the test is started, the load will switch between level A and level B
every time it receives a trigger signal. Setting the pulse width will not work in this mode.
