Did you buy this by gun point? These gen's are $1,495 new. :(

Close by, it was some liquidation where they had it, was not tested just powered up in the picture so I took a chance. Now at the closer inspection it seems that the function generator output is bad since I get nothing on the 1st BNC to the right - only get the pulse/square out (2nd BNC from the right) and the rest of the SYNC outs. Luckily, I found a full manual with the service schematics so hopefully I can figure it out.

There was one more seller with this model of Wavetek who offered it to me for $150. I am PM-ing you the details since you were interested, otherwise if you are not just post the details here. :)

I cannot emphasize how important Ebay is for test equipment.  I live and die with equipment off there.  Most of my test equipment I get for less than 1/10 of what it cost new!  Of course you have to read the fine print and know what you are doing but for us old timers, what a deal!

Amen to that!

Preliminary note only:

Results with ferrite antenna transformer, 2 IN4148 diodes and LED. All tests done with "open air" circuit (no breadboard -- no capacitive metal anywhere close, no earth connections).

No problems getting LED to light.

Coupling from signal generator::
Presence (or absence) of series capacitor (470pf) or inductor 2,2uH in signal generator supply line make no difference to operation.

Diode type used for Avramenko Rectifier (AR)::
Testing several types of diodes suggests that diode capacitance needs to be low. Circuit worked poorly with ultra high speed power diodes (medium junction capacitance) and did not work with 200V schottkey (highest junction capacitance). These results suggest that low serial capacitance is required in the load for optimal output.

Capacitive load tests::
Placing series capacitance in the load dramatically reduces the output while placing parallel capacitance enhances the output. Parallel capacitance on the load does not effect the resonance frequency.  Capacitance to ground on the load side enhances the output although the resonance is shifted to a lower frequency - as you would expect.

Load diode orientation::
Same operation with load LED in either orientation. Similar output power with two LED?s in parallel. No output with two LEDs parallel in opposing orientation. It appears that a polarized capacitive load is required for operation.

Preliminary finding on capacitive load::
Parallel capacitance is required on the load for function. This can be provided by capacitive coupling to ground or across the AV plug directly or via the junction capacitance of a load diode.

Square vs sine wave drive::
Both sine and square waves work just as well at the fundamental resonance. Square wave works better at sub-harmonic frequencies.

Principal resonances with no load to ground::
The fundamental resonance with no capacitive loading to ground (15ph scope probes) on the load was 12Mhz. Sub harmonics that give significant output are the 1/3 and 1/4. The principal frequency of 12Mhz gives the greatest output.

Principal resonances with load to ground::
With symmetrical 15pf load to ground on the output the principal resonance was reduced to 9.4 Mhz. Both 1/3 and 1/4 sub harmonics were present. The 1/4 frequency (2.34Mhz) now give the highest output. The waveform of the 2.34Mhz resonance is a rounded triangle wave indicating 3rd harmonic (almost a text book example of triangle wave synthesis with first and third harmonic components). The principal resonance was observed directly and in ringing on square wave drive at lower frequencies. Measurements of the frequency on the ringing confirmed the presence of a single principal resonant mode.

Load waveforms::
At all times the signals on the load were in phase but had a DC offset.
 
Single and double ended drive::
The circuit works similarly with single or double ended drive to the primary.

All tests were done with a HP33120A signal generator (10 Vp-p output). Measurements were made with Tektronix TAS 475 scope (100MHz 4 trace). Unless indicated otherwise all scope measurements were done with 10X scope probes with tips held close to leads to eliminate load effects on the measured circuit.

The next tests will look at antenna transformer ? number and direction of turns in the primary and secondary and alternate cores. I will also measure the Q of the principal resonance. Load tests will look at inductive influences.

Cheers

mark.

I don't know whether to be alarmed or just disappointed, but I tried to re-view Cold Electricity Part 9, and could no longer find it anywhere!!??

Hi Mark,
many thanks for the tests.
Yes around 12 Mhz I also get now the best light output, but still better when the core is removed.
As I only have a 10 Mhz scope the measurements have to be done with the horizontal 5x zoom factor, as my deflection time only goes to 0.5 usec.
The new IC 40106 is now much better and I will later post pictures and a new video.
But I still think I dont have the right cores, cause I dont get any amplification...

P.S. I still have a few ferrite fridge magnets laying around here.
I will later also wound 2 coils around them and try these.
Ben, did you use Litz wire for the primary coil in your magnet-coil setup ?

@Mark
Thanks for the detailed test report.

I am having limited success.
Signal generator, HP 33250A, voltage 10 V. Oscilloscope Tektronix TDS2014B.

Using the specified core.
I can light up red LEDs not very bright at 3.610 MHz. Neon light up occasionally. Generally the circuit behavior is very itratic. I can not light up blue LEDs.

I have not observed much difference between square wave or sine wave.
I tried driving up to 20 MHz slowly but no cookies.

From my breif experience I would say:

3.6 MHz is probably the 1/4 harmonic and is best stimulated with square wave. THat would put the fundamental at about 14.4 Mhz.
When driving at 3.6 Mhz with square wave prove the output at the common base of the AP by placing the scope probe tip close to the wire. The signal will only be in the mv range but it should be clean. Is it a rounded triangle wave? ... if it is then this is the 1/4 sub harmonic.

To get much higher output and more reliable opperation clip two scope leads (10X) to the output LED. This will shift the resoances lower but does dramaticaly increace output voltage.

Mark.

@MarkSnoswell

Pardon me for being presumptuous, but I believe we know each other, that is, we have known each other for a long time. If I recall correctly we used to be on some 3dsmax plugins beta teams and what not and we know the same people. Or perhaps a hint would be 3DLuVr?

Just the most unlikely place that we'd meet after so many years, did not know you had interest in alternative energy.

Sorry to be off topic...

In other news, I have fixed my Wavetek 191 so it fully works now with all waveforms. Prior owners have done a botchy job in replacing the BNC female connector and there was no contact.

My resonance are found around 11MHz and 19MHz, will find out exactly soon. I still do not see my neon light up...humbug.

EDIT: resonances at ~3.01MHz and ~9.51MHz

@Mark
Thanks again. My observations were only with the signal generator attached. If the scope is connected the OP seems quite strong. The Blue LED turns on quite nicely then.


@DrStiffler,
I have a batch of the 680uH cores and as they are the critical part of this investigation I wanted to clear up a few points.

1- The number turns you specified at 9 turns but I count 11 in the picture.
2- You did say that the sense of the L3 should be the same as the L2 core. Please can you verify that. Either my L2 cores are wound the wrong way by the manufacturer or the  image may be mirrored somehow.
3- You use a symbol for the L2-L3 combination which indicates 3 different windings. L2, as arrives from the supplier only has one winding. Am I missing something?

regards

AM

Thank you Ron for posting the link. Must have been a glitch in my IE ???
I've added it straight to my favourites folder.

Fascinating stuff! Eagerly awaiting the next "Chapter"!  :)

Okay, hereare for now already 4 pictures of my new tests.

I just rewired the 10 turn coil around the Litzwire coil into the other
direction and guess what, I for the first time saw
now the neon bulb glowing really bright,
but only, when I don?t use the core...
Hmm...

Check this out.
The winding direction of the 2 coils seems to be very important !

I also recorded 2 videos while playing with the setup
and you can see, how I suddenly stumbled onto the
neon bulb glowing brightly for the first time.
But you will also see, that the LED still is brighter,
just without my cores...just the coils alone...

I have toconvert now the videos from the camera format
to amore commom format.
Stay tuned.
Maybe I could buy from Ron a verified core, so
I could really test it with the amplification...

P.S.: My AM Litzwire coil has indeed 2 coils on there, one larger turn coil
and one smaller turn coil,cause it also was used for longwave in the
radio I got it from..

So you see 4 litzwires coming from the coil plus 2 wires from the 10 turn coil around it.

The thing at the right side after the big red 470 pF  is the 2.2uH coil,
it looks like a resistor but is actually a coil.

I had modified the 40106 oscillator circuit this way, that I have now
only 3 hex-inverter drivers in parallel and am using
2 inverters after the single oscillator inverter to
"sharpen and fasten" the waveform.

Maybe as the circuit seems not to need much current,
I should only use one inverter as the output driver and
use all the others to fasten the waveform ?
I will try this later...

The scope you see shows about 12 Mhz waveform.
I used in this test a powersupply with 12 Volts DC
and the amplifier on the scope is set to 5 volts /div,so
the AC amplitude was about 8  to 9 Volts peak to peak.
It was measured at the last driver output directly.
the scope ground was connected to the circuit ground.
The scope was grounded, but I did not need now the
metal mesh what I normally used at one LED pin.

The ground line of the scope was directly in the center of the scope screen.
If you have questions please let me know,but maybe you will
just wait for the 2 videos.
Regards, Stefan.
