Details
The pulse trains associated with the indicated tags will be generated simultaneously. This is useful when testing
devices such as voltage regulators, where the input signal and output load must be applied to the instrument at
the same time.
When using this function, each tag1 pulse will encapsulate each tag2 pulse in time. Specifically, the tag1
pulse will transition from its bias level to its pulse level before the tag2 pulse. Both the tag1 and tag2 pulses
will return to their respective bias levels at approximately the same time. Measurements for both pulse trains take
place at the same time (see the waveform in the figure below).
To provide this encapsulation, the following rules are enforced:
• The tag1 pulse on time, ton1, must be configured to be > 40 μs longer than the tag2 pulse on time.
•
The tag1 and tag2 pulse off times, toff, must be the same.

A Boolean flag; this flag will be true when the pulse was successfully configured,
false when errors were encountered
A string message; if the f flag is false, msg will contain an error message; if it is
true, msg will contain a string indicating successful configuration
Numeric identifier of the first pulse configuration to be initiated
Numeric identifier of the second pulse configuration to be initiated
