@tedyapo UHF RFID! It probably speaks EPC Gen2
@gsuberland maybe you could use an RF power detector IC after AC-coupling, something like the AD8318 used on this board? sv1afn.com/en/products/ad…
@DanielBogdanoff @smellsofbikes @Keysight looks like it uses another port from the PNA-X, through a few splitters, to feed a trigger signal to the sampling scopes
@tedyapo it's a regular scam i've seen on there a lot. they'll compromise an account with good feedback, spam it with listings for expensive stuff, and try to get people to pay off-site
hmm, i think there's something wrong with this etch a sketch
@f4grx @lukeweston Yep, this one's a C-L-C T-match and I'm adjusting the caps

Happy release day! HackRF 2022.09.1 is now available: github.com/greatscottgadg…
@lukeweston oh no. if that pin is extended as far as it looks, i wouldn't plug it into anything
@mightyohm in the group photo, the green one looks like a perfect match s.alicdn.com/@sc04/kf/Ha8bd…
@mightyohm this one looks really close: alibaba.com/product-detail… - same ribs on top, same handle, and same valve
@ExplodingLemur might need to press down to get the next page and set whether to trigger on reads, writes, or both
This weekend I added support for the Agilent 86100A sampling scope to glscopeclient/scopehal, along with support for GPIB adapters using the linux-gpib library. Here it is showing a 10Gbps eye diagram 🤩
I tested across the switch that selects between inputs and there's definitely a fault in it, but it's got a spare input! So I swapped the cable over and modified the control cable to swap the signals
Tracking down an issue where my sampling scope wouldn't trigger on one of the inputs. VNA trace suggests there's a hairline break somewhere, since there's a lot of loss at low frequencies but S21 increases with frequency (due to capacitive coupling):
