The unit has the usual features found in these USB instruments: configurable pre-trigger buffer (hugely important), a variety of protocol analyzers, and cursors. You can set up any one channel to be an edge or pulse-width trigger the others then qualify the condition by logic state (0s, 1s, or don’t cares). Pretty impressive for a small unit like this. Broadening that to 30 ns the device captured the data, and the cursors showed it was indeed 24 ns. I can’t generate a pulse like that, but ran a 24 ns pulse in, telling it to trigger on one under 20 ns wide. Width can be adjusted to as low as a range from 1 to 2 ns. The unit will trigger on a rising or falling edge, or on a pulse of a settable positive or negative duration. Matter of fact, you could set up a development lab on an airplane’s tray! I suspect the flight attendants wouldn’t be too thrilled. With the Logic Pro connected the battery level went from 100% to 55% in three hours.

A Mac Air runs about 9 hours on a charge.

A quick measurement shows the instrument draws about 310 mA from the host’s USB port. I connected it to my Mac Air, as the Logic Pro’s tiny form factor just screamed to be paired with an ultra-portable. Too few tools support all of these hosts.

The channel tool on the web site lets you know how long your host computer can record data in real time generally it’s minutes to hours. I found voltage readings accurate to about 0.1%, an astonishing number for a scope. I really like the 12-bit A/Ds and +/- 10V input range. The web site does say that the fastest digital signal allowed is 100 MHz, lower than the Nyquist cutoff, but probably realistic given the wire probes.Īnalog channels sample at 50 MHz or lower, again depending on the number of channels at play, with a -3 dB point at 5 MHz. The tool is nice but I’d sure like a clearly-spelled out set of specs instead of having to puzzle out the product’s behavior by trying different combinations. Their web site has an interactive tool that lets one see what rates are possible, depending on the combination of channels used. Enable more, or any analog collection, and the rate drops off. Though rated at 500 Msps that’s only if one is using four or fewer digital channels. So I would not use this as a scope substitute think of the analog as a way to see what is going on in that domain while triggering on digital data.Įach channel can accept digital or analog data – or both at the same time. It’s not like a scope that repetitively and constantly updates the display. However, it can gather so much data (limited by the memory in your host computer) that in most cases this will not be much of a limitation.įunctionally the unit is like a logic analyzer: you command an acquisition, which is then displayed.

The Logic Pro 8 doesn’t have any analog triggering modes so isn’t quite an MSO. An MSO critically offers the ability to trigger from digital and/or analog channels so you can see their interaction in real-time. The MSO is one of the more important tools for embedded developers, as it shows both analog and digital information at the same time. It occupies an interesting hybrid space between logic analyzer, oscilloscope, and mixed-signal scope (MSO). I called it a logic analyzer but it is more than that. The iPhone 6 reputedly bends if stored in a rear pocket this device most definitely does not.

Unlike most USB instruments, the thing is beautiful, solid, and even comes in a zip-up traveling case, though is so small a shirt pocket could hold it plus the requisite pocket protector. They sent me a Logic Pro 8, which is in a stunning solid-metal case about 2”x2”x3/8”. Instead, the company offers inexpensive 4- and 8-channel devices, and recently added 500 Msps 8- and 16-channel instruments. That product doesn’t seem to exist anymore. It is inspiring to see a new generation inventing complex electronic products.Ī couple of years ago I reviewed their Logic 16, a 100 MHz, 16-channel, USB-based logic analyzer. Saleae is a small instrument company based out of San Francisco comprised of bright young folks who make me wistfully think over the decades since my friends and I were the young bucks.
