This works really well. I've read the good reviews on yt, and was still surprised. Some of the specs are a bit over-rated, but that's normal for the source. It does accurate sine waves to 60 MHz, and other waveforms seem accurate to about 2 MHz. At 60 MHz it'll do 3.5Vpp, and 20 Vpp at 12 MHz. For a 5v sine wave, my scope says 3rd order harmonics are down at least 44dB, so not bad. For square waves at 5v, rise time is under 10ns. Has a lot of useful built in waveforms, including log and reverse log and random. Haven't played around with modulation yet, as I really don't need that for my purposed. It ships well protected, with 2 serviceable bnc to alligator clip leads, a usb cable, and a short power cable. Shipping was quick. The only negatives are that the ink/paint on the white rubber buttons wore off already on one, so I'll have to figure out how to fix that. The case is light enough that you have to hold the box with one hand to adjust with the other, but that was expected. I may weigh it down, but that might mean I'll need a stronger front stand piece. No manual, so you just have to play around with it, but that was expected given the source, too. All said, it's a handy thing. Fantastic value.

It'll say this carefully. If you are 100% certain that you already have a crimp tool that will fit this, then there is a 50% chance that you will be able to get it to fit, if you are good with machine tools. Or in other words, it is a completely non-standard die.

adapters are good, low loss to at least 3 GHz, and work fine.

This little thing works great! This lets you set single frequency or a step-wise sweep, with control of the step size and step speed for the sweep, which is pretty cool. Not sure what the waveform is, haven't looked at it with a scope yet, but the frequencies seem fairly clean on the simple SA I've used on the high end. At the 35 mhz side there appears to be quite a bit of harmonics, but that's probably to be expected from something so broadband. Levels seems pretty accurate, too, or at least up into the 2GHz range. it does -4dBm to +1, four steps. Thinking levels are a bit lower up to 4.4 G, but that could be coax loss or my receive meter. It does cover the full range. All in all, a great little gizmo.

This is a well made wide spectrum RF detector. It has an internal rechargeable battery, and comes with a charger and two SMA antennas. Sensitivity is adjustable to either pickup random background RF, or to let you home in on a local signal source. It obviously won't detect electronics that aren't transmitting, but will clearly identify a cell phone or computer wifi transmitting within a few inches. Pleasantly surprised at this. The only negative is that the gold color is a little weird to me, but that's minor.

These work well. The tension is nice. Not really too adjustable, because most of the tension is set by the friction of the pin drivers and the body, but the tension is good anyway. The practice lock is actually harder in some respects than a real lock, so that's a plus to me. The downside? The buildup of the pin driver near the end isn't great, so it slips off the practice lock easily. Maybe that's intentional, so that it won't break a pin, but it makes use of the practice lock difficult to impossible. I may fix myself with epoxy or something.
