Hi.

I managed to locate my spectrum analyser this evening, it was stored away in the garage in one of the many boxes.
It must have been around 2007 when I built it and it's not 100% complete but good enough for testing.

I made my own PCBs, the RF board being double sided and the other two boards, sweep/video and psu/marker being single sided. I regret not making these latter two boards using fibre glass copper clad board, never mind at least the RF board, the most critical one is.
The housing is an old Pace analogue satellite receiver box with a new modified front panel to accomodate the various pots, switches, and attenuator etc.

If my spectrum analyser turns out to be successful, then I hope to rehouse the electronics in a modified oscilloscope case so that I can have an integral display.
I hope to test my unit over the coming weeks as things have become busy once again plus there are a few outstanding projects that have to be completed before proceeding to this one.

Attached are a few pics.

Pic 3 is the RF Board
Pic 4 is the Sweep and Video Board
Pic 5 is the Power Supply Board which also includes the marker generator

Regards
Symon
