For one project I needed to do some analysis on a 12V signal. Rather than knock together a potential divider with a couple of resistors I thought I’d do it properly and build a small PCB to do the job which I could also reuse again. The attenuator board plugs in between the saleae and the probe. As it worked well I thought that if I needed this functionality then there would be other people who would. So, I added a capacitor for low frequency compensation and had a batch built. The attenuator provides a 10:1 division on each of the four channels on the probe. In case anyone is interested, more information can be found at my website [http://www.hunterembedded.co.uk/products/](http://www.hunterembedded.co.uk/products/) ---

This is great @iain! Good to hear from you again and thanks for sharing! I just added information about your probes under the Community Created section of our Accessories support article: [https://support.saleae.com/user-guide/using-logic/connecting-accessories](https://support.saleae.com/user-guide/using-logic/connecting-accessories) ---

Hi @iain, I find myself in a very similar position to you, but I see that your product is no longer available. I wonder if you are able to share the schematics/values of components that you found worked well so that I can build one up a DIY one? ---

Hi Michael, I still have some available @ £20 + tax + shipping. I just don’t sell them on amazon anymore. The values of the components were R1+R2 in serial 9Mohm (6.8M +2.2M) with C1 of 1.1pF in parallel. Iain ---

Thanks for your quick reply - I’ll have a go at DIYing it for now but I know where to come if I need a more robust solution. ---

@iain are these attenuators still available? ---

Yes. you can email me at [iain@hunterembedded.co.uk](mailto:iain@hunterembedded.co.uk) if you want to order some.
