PrOgrAm SEquENCES
The 63600 series offers 100 programmable loading sequences that enable the user to simulate various real world conditions. In addition, each module can
be operated independently or synchronized so that all modules start operating at the same time while running independent programs. Below are some
examples of the most popular program sequences available.

The unique CZ mode designed in
63600 series can improve the loading
behavior of CC & CP mode and makes the
simulated loading current more realistic.

Modern electronic devices operate at very high speed and demand
rapid transient response characteristics. To address these applications
the 63600 offers high speed, programmable dynamic loading, sweep
simulation and control capability never before achieved. The right
figure shows the programmable parameters which can be set within
the 63600 loads: Waveforms can be single shot or set to repeat.

The 63600 also offers a unique dynamic frequency sweep with variable frequencies up to 50kHz. This capability is ideal for determining worst case voltage
peaks (see Figure 1). Measurement of the Vpeak (+/-) can be achieved by this function with a sampling rate of 500 kHz (Figure 2). The dynamic loading
mode can simulate different loading conditions for most test requirements. Dedicated remote load sensors and control circuits guarantee minimum
waveform distortion during dynamic loading.
The dynamic mode provides a unique simulation
capability allowing users to set the number of
times each cycle repeats from 1~65,535. Feature is
excellent for determining the peak current which can
be sustained by converters.
