USB testers: T18 / UD18 / UD24
dophuc:
USB tester T18, UD24 seems a bit expensive and functions quite limited. You should check out USB testers like Fnirsi FNB48, AVHzY CT3 (Shizuku, KT002). These USB Test types have many functions, can test charging protocol (QC 2, QC3, PD, AFC, FCP, PPS...), trigger Volt and current, check ripple noise, cable resistance, check battery capacity, run LUA script... FNB48, AVHzY CT3 also has PC software to record Charging data, voltage and current information, firmware upgrade...

Hi,
I wonder if anyone came across some sort of usb tester (mostly power/qc/pd) made by not chinese company. Not that I don't like chinese stuff, but most of these atorch/ruiden/etc is a "single day" device, meaning it was made (all presumably by avhzy) with some very raw software, not even closely well thought or well work tested and left that way with no support or software/firmware updates. I've tried many of those and lord, I'd pay 100-300 usd for a really normal device like West Mountain Radio CBA Electronic Load instead of Atorch whatever electronic load.
CBA does not have any kind of display, but it works like a horse with normal software, it's stable and highly useable for repeated tasks.
While almost every usb tester made these days has many whistles and blows but lacks normal straight forward idea for what's it is made for (along with software).
Sorry for ranting, struggling with this particular piece of equipment...

I have Atorch J7-C (UC96). I am quite certain that it does NOT have PD trigger.
Are there any testers with both built-in triggers and DC connectors?
There are UD18 and UD24 with PD connectors but they do NOT have PD/QC voltage triggers (sauce: UD18, UD24).
Which is kind of sad, considering they HAVE barrel DC connectors.

Necro of an old unanswered post...
No, it's not sad. USB QC and PD Triggering is specifically for USB. There are no data lines on a DC barrel jack, and hence absolutely no way of triggering anything on a simple 2-wire power line.
A Power Supply with a DC Barrel connector cannot be triggered, so why would you need to have "triggering" in a tester for such power supplies?
To make the trigger work, you must be connected to a USB power supply (with suitable capability) then supply the Trigger signals to the power source via the USB Data (for QC) or CC (for PD) connections. Thus you must use a USB cable that is suitable for that task, you cannot make that connection to the power supply using a DC Barrel cable.
If you have a "non-triggering" meter like a UD18/24 you can insert it into the corresponding USB power outlet port, then insert a QC or PD Trigger into one of the available OUTPUT ports on the same tester. Alternatively, you can use a pass-thru trigger and place the tester after the Trigger, with the load hanging off the tester.
- This will allow you to pass the required QC/PD trigger signals back into the power supply and make it switch voltages.
In the case of the UD you could plug in a trigger to the USB Output, then draw a load from DC5.5 Output or Type-C Output. Or plug the trigger into Type-C Output then draw the load from USB Output or DC5.5 Output.
