SQUARE WAVE HIGH AMPLITUDE FUNCTION PULSE GENERATOR VINTAGE - BRAND NEW HV FLUKE PROBE SWAP?? BREXIT

SQUARE WAVE HIGH AMPLITUDE FUNCTION PULSE GENERATOR VINTAGE - BRAND NEW HV FLUKE PROBE SWAP?? BREXIT

SQUARE WAVE HIGH AMPLITUDE FUNCTION PULSE GENERATOR VINTAGE - BRAND NEW HV FLUKE PROBE SWAP?? BREXIT

(OP)
Hi. I'm trying to get hold of a function generator or even just a square wave generator which can output up to about 50V.
Something old and cheap is fine if it works.
I have seen a Tektronix 106 (in the usa), which would do the job, but does anyone know of any other device which would be capable of this, so I can widen my ebay search.
The ebay descriptions doesn't generally state the maximum output amplitude of old wave generators.
High output frequency isn't really important, but even better if it's available.

If anyone on here even has something suitable for sale I would be interested, and I would even be happy to do a straight swap for a brand new £200 Fluke 80K-40 HV probe that I have.
It is unused.
e.g. https://www.fluke.com/en-us/product/accessories/pr...

I am in the UK so buying from usa isn't so practical as the price quadruples by the time it gets here.
I wonder if a "UK USA TRADE DEAL" after Brexit means we can buy kit from the usa more reasonably?
That would be nice smile

If the required frequency is not too high, then it might be quickest and easiest to lash up a perhaps MOSFET-based trivial amplifier.

Squarewave is just On/Off, so there's not really even much design involved. Use a lower power signal generator to drive the gate.

The required power supply would presumably be any available adjustable bench power supply.

Depending on your grounding and common circumstances, you might need to also lash up an isolated floating driver. Perhaps a battery powered 555 circuit.

The requirements could probably be met by feeding a low level signal into an audio amplifier.

Thanks, but to be honest I was hoping to just buy something I could use straight off. If I built something from scratch I wouldn't have much confidence in it. Even just reading the datasheet makes me shy away from building it. I don't understand half, (more like 99%!!) of what it is saying.

An HP6826A or HP6827A driven by a suitable low voltage function generator would probably do what you need, or its bigger brothers the BOP Series from Kepco. All are old-school and obsolete (and often a bargain...) but essentially they're high power, high voltage Op-Amps which can take a low power, low voltage signal and provide voltage and current gain.

Or find a DC-coupled audio amp as others have suggested.

Ok. Thanks. I will investigate those options.

I just came across this item which should do my job if it does what it says it does. i.e. output voltage is the same as supply voltage. And the supply voltage can be 30V. For the sake of a few pounds it's worth a try. Thanks
