These option-WJ models aren't very common; this is the first one I've seen. It tunes from 5 kHz-8 GHz in two bands which are both wider than normal 492/492A analyzers cover; you can see the spectrum from near DC to 4.2 GHz in a single sweep.
If you don't need full coverage to 21 GHz, this 492A may be a good alternative to the more-expensive entries in the 490 lineup!
