== RF.Spice A/D vs. B2.Spice A/D ==
[[RF.Spice A/D]] is now an extensive superset of [[B2.Spice A/D]], offering additional RF simulation capability plus a comprehensive library of system-level black-box virtual blocks. Due to popular demand, EMAG Technologies Inc. continues to offer [[B2.Spice A/D]] simply as the '''"Lite Version"''' of the [[RF.Spice A/D]] product. The [[User Interface|user interface]] of the two products are now identical and both share the same consolidated documentation including the and tutorial lessons. However, the users of the [[B2.Spice A/D]] edition will find some the following submenus of the '''Parts menu''' greyed out: * [[menusMultiport Networks]] * [[Transmission Lines]]* RF Devices* Waveform Generation Blocks* Analog Signal Processing Blocks* Digital Signal Processing Blocks* Spectral Processing Blocks* Modulation Blocks In addition, all the transmission line calculator and transmission line designer utilities under the Device Manager's '''Tools Menu''' are greyed out, and so are the RF device and model import and creation items in the Device Manager's '''File Menu'''. Needless to say, the parts database of the [[B2.Spice A/D]] edition is a subset of the parts database of [[RF.Spice A/D]].
