Next, I measured the coil resistances.

The analyzer allowed me to see the frequency move around as I changed the current on the tuning port. Save my name, email, and website in this browser for the next time I comment. Before verifying the suspected power level, I used an inline attenuator to avoid any chance of damaging the machine. Notify me of follow-up comments by email.

The thick wire is the main tuning coil, which accepts 0. Note the hand made labels which may explain the cost of these units avsntek purchased new… looks like US style handwriting to me. The closest standard units appear to be the AV through AV, which cover 8 to To look inside, carefully removed the top weld seam on a lathe, and the you can pry the case open.

SimonsDialogs — A wild collection of random thoughts, observations and learnings. At the upper end of The particular oscillator I received is marked with model number SO and is labelled for 7. Varying the coil current — no effect. Notify me of follow-up comments by email. There are quite a few of the miniature Stellex units on eBay, but they generally don’t go much past 10 GHz. Also probed other parts of the circuit, with a thin wire, under the microscope.

These do require a good amount of power, avanetk coils, etc, but provide stable and rather low noise output, and good modulation capability.

Power levels seemed to vary between 7 and 13 dBm across a wide range, however the analyzer calibration may be off somewhat. Sorry, your blog cannot share posts by email. However, for the current unit under investigation from a GHz frontendtype S, 8.

The lower edge of the specified range 7. This is for much lower currently but high bandwidth modulation. It matches the first pinout in this old spec sheet. Your email address will not be published.

With the specs determined, I now have enough information to continue work on my project using this oscillator. With mA flowing, a signal finally popped up at around 7.

Well, with all the basics checked, what to do with such hermetically sealed unit, other than using gig to satisfy my curiosity about its internals. Leave a Reply Cancel reply Your email address will not be published.

A range of 6 dB matches the units on the spec sheet, but a 7 dBm minimum power is below that of any of the comparable modules. For a project I am currently working on, which I will detail here too eventually, I needed an oscillator capable of covering 8 to 12 GHz. The coil — rather, the coils. This is possibly throught the side opening, which is usually welded shut, but can be drilled up rather easily.

Since this particular project wasn’t very sensitive to any of the parameters, I waited for a cheap one to show up with the right range and went for it. To determine the likely power output, I hooked the oscillator into a dummy load, then measured the current draw on the 15V input — it was almost exactly mA, which means it is probably a 30 mW Current consumption on the 15 V rail is normal. What you can see is pretty straightforward, despite all the gold wires.

As expected from this helpful documenta fair amount of tune current was required before oscillation started.

Then, join our amazing community. Hope to trace the defect to some specific part. A19 board, YTO unlock, bad precision trimmer s. Notify me of new posts by email.
