I would like to know how to use the CW505 Planar H-Field Probe. My English skills are weak, and I also lack technical knowledge about side-channel attacks. From what I’ve researched, it seems that the old GUI is no longer available. It was mentioned that the usage instructions are in the tutorial, but I couldn’t find where they are located. I would greatly appreciate any guidance from the knowledgeable and kind experts here.
Have a look here: CW505 Planar H-Field Probe - NewAE Hardware Product Documentation
The video shows the old GUI, but the principles are the same. I would recommend that you first go through our SCA 101 courses with shunt measurements, then switch to the H-field probe.
Thank you for your reply. I’m still working through SCA101, so I think I’ll wait until I’ve made a bit more progress before I ask more questions.
On a different note, I’m currently studying with the ChipWhisperer Nano. In the video you linked, they connected the ChipWhisperer main unit to a probe, but is it not possible to perform electromagnetic attacks with the ChipWhisperer Nano? I apologize for the different topic, but I would appreciate your answer.
It’s possible. You’ll need to break off the target portion of your Nano as described here, then solder an SMA connector on the capture portion, and add jumper wires between the capture- and target-side headers.
(None of these modifications are required if you have a CW-lite (2-part version), or CW-Husky.)
Thank you again for your thoughtful reply. I’m not sure if I can handle soldering, so I’m considering quietly purchasing the ChipWhisperer Lite instead. Do I need jumpers for the ChipWhisperer Lite as well? Also, if you know of any guide pages on how to set jumpers, could you share them with me?
I feel like I’m asking a lot, but I’d really appreciate it if you could answer.
With the CW Lite 2-part version (mouser link), or CW-Husky, no soldering is needed.
Jumper connections are needed only if you break your Nano. You would solder headers onto J3 (the 20 holes at the top of the capture side) and J6 (the 8 holes on the side of the target side) and use those headers to reconnect the connections that get broken when you break the target side; see the schematic here.
Thank you for giving me so much advice. I’ll think about it a bit more. If I have more questions, I’ll ask by topic, so I’d appreciate it if you could answer.
