In this video I have a go at making a DIY HP 11683A range calibrator for HP RF Power Meters.
Stay tuned for the final working version in the next video!

J'adore, je suis pas au niveau pour en avoir besoin maintenant. Ce que j'aime le plus c'est la somme de travail et les progrès accessibles aux amateurs, fini les boites en pcb, les circuits en l'air, etc.
Very professional work.
I have seen many power meter on ebay without sensor, so at this time i play with ad8307 and analog voltmeter. Thank for sharing your knowledge

Really nice work - I have an 11683A but every now and then I get questions about how to get one - Did you ever do the V2? I'd love to point people to this.

Nicely done. I would like to get one when the final design is completed. Let me know to get it. Thanks

Maybe instead of using rotary switch go for reed relays? I know it's gonna be a bit bigger, you will need some control voltage for relays but could be better then looking for good quality rotary switch.

Where can I order this calibrator? Looks very nice.

Nice form factor 👍 tidy as!

Just for experiments sake I'd try it with battery power too. Not too fond of USB power for this kind of sensitive analog stuff myself.
cheers, Wilko

Not sure which type of dcdc converter you used at the usb input but in the past I had quite some issues with strong emc regarding these small four pin SIL converters… but I guess you‘ve done your filtering properly. Perhaps two relays for the two smallest ranges?

👍👍👍 I just subscribed to your website. I'd like to buy one of these kits when you've finished the design. Nice work so far. Thank you for all your efforts.
