This function initiates the pulse configurations assigned to tag1 and tag2. 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 device at the same time. When
using this function, each tag1 pulse will encapsulate each tag2 pulse in time.
That is, 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 Waveform below).
To provide this encapsulation, the following rules are enforced:
• The tag1 pulse on time, ton1, must be configured to be at > 40usec
longer than the tag2 pulse on time.
• The tag1 and tag2 pulse off times, toff, must be the same.
tag1: Numeric identifier of the first pulse train configuration to be
initiated.
tag2: Numeric identifier of the second pulse train configuration to be
initiated.
A Boolean flag. This flag will be true when the pulse was successfully
f:
configured, false when errors were encountered.
A string message. If the f flag is false, msg will contain an error
msg:
message. Otherwise, msg will contain a string indicating successful
configuration.
None
