Potential Pulse and Square Wave
In the Potential Pulse and Square Wave test, the SMU potentiostat supplies a series of up to 100,000
potential pulses. At the end of each pulse, the SourceMeter measures the resulting current. You can
select both the peak and base levels of the pulses, as well as the period, pulse width, and sample
time.
Various parameters of the pulse wave are displayed in the figure below. Though not pictured, there is
also a brief latency period between the end of the measurement and the end of the pulse to allow the
instrument’s analog-to-digital converter to finish processing the reading.
Figure 61: Potential versus Time
To ensure proper instrument operation, the potential difference between the reference electrode
(RE) and counter electrode (CE) terminals and between the working electrode (WE) and working
electrode sense (WES) terminals should not exceed 5 V.
