Figure 1. Make time-critical measurements on fast-changing or pulse-like loads. An external trigger initiates the acquisition. Programmable delay and measure
times enable measurements at a specific time on the load current pulse. In addition to the digital trigger, a level threshold setting can be used to store up to
2500 measurements at a programmed reading rate.

Performance
To monitor fast-changing and pulse-like load currents
properly, Series 2280S supplies offer the speed necessary
to capture load changes that occur at intervals as short as
140µs. This capability allows designers and manufacturers
of portable, battery-operated devices to monitor load
currents easily in all of a device’s operating modes so they
can determine the device’s total power consumption.
The bright, 4.3-inch TFT display shows voltage and
current readings, the source settings and many additional
settings in large, easy-to-read characters. The icon-
based main menu provides all the functions users can
control and program for fast access to source setup,
measurement setup, display formats, trigger options,
and system settings. Menus are short, and the menu
options you need are easy to find and clearly described,
so that you can set up test parameters quickly by using
the navigation wheel, keypad, or soft-keys. Many set-up
parameters, such as for voltage and current settings, can
be entered directly from the home screen; less complex
tests don’t even require accessing the main menu to
make adjustments. Whether your test’s requirements are
uncomplicated or complex, the Series 2280S supplies
provide a simple way to set up all the required parameters.
This high speed measurement capability allows measuring
each state of a power-up load sequence and a power-
down sequence. Measurements can be made as fast
as 2500 readings per second, making it possible to
characterize and test the current draw at each of the start-
up states.

mode, protection levels, and other functions from
