Usage
f , msg = InitiatePulseTestDual( tag1, tag2 )
f A Boolean flag; this flag will be
true
when the pulse was successfully configured,
false
when errors were encountered
msg 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
tag1 Numeric identifier of the first pulse configuration to be initiated
tag2 Numeric identifier of the second pulse configuration to be initiated
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.
