Voltage Source, Best Performance

When the 4225-PMU is used as a voltage source only (no measurements of voltage or current), the timing performance is improved. The following

is provided to offer a clearer idea of best performance when used as a voltage source, as achievable under optimal conditions. This should not be

interpreted as a guarantee.
