One of the most useful things about DTT is the ability to capture references, and plot them against current measurements. However, reuse of this feature for the same reference with several different measurements (i.e. a template) is destroyed because whenever one closes as saved DTT file that includes a reference, upon re-opening the frequency vector of the reference is shifted by some large amount (in my case, it seems to be exactly 1/BW = 100, but that may just be numerology). For example, check out my "before" vs. "after" saving plots attached.

This is a bug already in place in BugZilla, under bug 254 (and actually has been put in many many times as independent because it had yet to be resolved, and then later removed as redundant), marked with HIGH priority, but the last activity on it appears to be October 2009. Of additional note to Daniel's comment (#5), this is an example of a white-noise transfer function, where the original bug report and his comment were in reference to swept sine transfer functions alone.

(Though all six of the 20110812_H2_ITMY_R0*.xml's show the same bug independently).
