The latest arrival is a Tektronix 492BP spectrum analyser. This guy runs from 10kHz to 21GHz and has a waveguide mixer (WM490K) which goes up to 26.5GHz. Apparently there are mixers available up to 325GHz.
The upside, well, this covers all the amateur bands. I mean, all of them, if I can get the mixers. But anyway it does everything I am likely to need for a very long time. The downside… space. it’s big. Mind you, so is the 5342A frequency counter. I need a bigger table. And I must say that describing this as portable is like describing a B40 receiver the same way. (well, ok, it’s half the weight of a B40)
I have written myself a mental note. First, do not use it until I get a decent DC block. Second, actually learn how to use it before I need to use it!
I am (still) gathering microwave test gear and have now acquired a rather nice HP frequency counter, good to 18GHz (but apparently tested to 20GHz). This will help once I begin constructing the numerous kits waiting their turn, in particular a 10GHz transverter.
Microwaves have interested me since my school days, not because of school but because I remember being interested and being at school. Actually, the interest probably dates further back to me seeing various microwave towers around the place and my grandfather telling me what they were.
Anyway, having something means trying it out… so here it is with a HT keyed on 145.5, and more interestingly to me a 6cm FPV transmitter held close by (until I realised it was getting hot!). The meter had not even warmed up for the 6cm test – me being impatient!
Now, I just need a signal generator and a spectrum analyser…
