Custom Pulses Made Easy With ARTool
By: Jerry Joseph, Product Applications Specialist
TGAR has an exciting custom pulse editing tool that is as easy to use as drawing a pulse on a piece of
paper. The ARTool (pronounced art – tool) allows the user to build custom pulses by piecing together
individual function segments. Once the pulse is designed and saved, press the GENERATE PULSE button
and the pulse is output to the DUT. This note details the ARTool and its capabilities.
The ARTool has many useful waveform segments in its toolbox to select from, including sinusoids,
triangles, drop outs, positive pulses, rising and falling ramps, exponential, and an ISO 7637-2 pulse 2b type
transient. Many segments can be strung together to make truly unique waveforms. Each waveform can be
generated repeatedly as needed for the test.
The DC supply can be turned on or off between pulses. All of the functions in the ARTool are generated
using the DC supply. For TG6032 the supply can output 0V to 60V at 32A, and the TG6100 can output
0V to 60V at 100A. The TG6032 amplifier has 70 kHz bandwidth and the TG6100 has 30 kHz
bandwidth. Rise/fall times for step functions have been measured to be less than 5μs for the TG6032 unit.
Like all TGAR test pulses, a report is generated automatically after the test is completed.
The main panel for the ARTool is shown in Figure 1. The following descriptions give a tour of the
ARTool main panel.
1. Pulse name and the standard that the pulse belongs to.

3. The Toolbox. The toolbox contains all of the segment functions available. Clicking on
any of the tools will insert that segment at the current location in the pulse.
4. Segment Sequence. This is the sequence of segments that make up the pulse. Clicking on
any segment will pop up the segment’s properties for adjustment or review.
