TRANSIENT OPERATION

The AMREL Programmable Electronic Load can facilitate testing sources and load simulation through the use of its
internal transient generator. This transient capability allo ws the user to determine operating specifications for instruments
such as a power supply. Th is capability also allo ws for pulse -charging a battery and for simulating battery drain or
simulating an electronic switch.

TRANSIENT MODE

Operating in the Transient mode, the eLoad offers 7 operating types: continuous, toggle, pulse, step, step auto, step once
and trigger. Each transient mode has a corresponding hot key, with the exception of the different STEP modes wh ich
instead is selected from the local menu, and TRIGGER, wh ich is remotely operated. The selected TR ANSIENT
operation is initiated using the PULSE hot key. After the input is turned on, and the pulse activated, the transient
operation will begin upon receiving a trigger signal or continuous mode will activate as soon as transient (pulse) is turned
on. If any of the STEP modes is activated via the STEP hot key, then the selected STEP mode will begin once input is
on.
All Transient Modes can be selected or activated by using their designated Hot Keys. The Step func tion has a separate
menu for setting the step value, time, and mode selection. The front panel "TRIGGER" hot key will trigger certain
transient modes when appropriate.
For Continuous mode, once the transient operation is activated the eLoad will switch between main level and transient
level based on the duty cycle, frequency and slew time.
For Pulse mode operation when amplitude and duration is programmed via GPIB or RS-232 bus. The trigger source
comes from GPIB or external TTL trigger.
For Trigger mode operation, the eLoad will switch to the set triggered level once a trigger signal is received (trigger
signal via GPIB, Ethernet, External port, or Bus). The triggered level can be changed to a value greater or smaller than
the main value setting.
For Toggle mode operation, the eLoad will toggle once between main level and transient level whenever it receives a
trigger signal from GPIB or external TTL trigger.
For Step/Step Auto/Step Once operation, the eLoad will switch to the new value setting based on the length and value of
the programmed step.
Trigger Out signal can be cascaded via the trigger out port to multiple loads or instrument application whe re the user
requires synchronized triggered events, such as activating different transient values for a group of eLoad. The trigger out
signal is a hardwired trigger signal with minimal delay.
