I think I see a serious problem with low-power operations. The crystal used by the DW module takes quite a long time to warm up, and settle down. Below are two diagrams. Labelled “Figure 2” on the left is DW’s version. On the right is a diagram copied from a comprehensive discussions of crystals from HP,
Notice that DW’s version has been edited to remove the important units.
Figure 25. A is a RTXO warm up curve. B, C and D are typical TCXO warm up characteristics. The long time (3 hours) is due to changes in temperature inside the instrument. E and F are oven oscillators. Stability is achieved in ≈20 minutes.
That might be a problem as far as instant startup is concerned unless we keep the DW crystal running.
