Innovative Tools. Excellent Service.
The Logic 4 is a logic analyzer with a well thought out and user friendly PC software which makes digital measurement very fun. Just plug in via USB and go.
The digital capture rate is 12 MSa/s on every channel. Because of the streaming and the USB 3 interface to the PC, the memory depth is unlimited. The logics also show analog signals because all digital channels are captured simultaneously with the A/D converter. The analog capturing is with 6 MS/s slower than the digital capturing, but it provides an insight in analog signal behaviour. The bandwidth of the analog capturing is 600 kHz (-3db). But the signal is already attenuated at this point.
The Saleae logic analyzer are perfect for the mobile use because of the hand pocket size.
Special features
Record
To record your digital and analog signals, just press start. You can fill your entire computer’s memory with data so it is easy to capture lengthy or rare events.
Setup
Every Logic device can be customized to capture data the way you want. You can select how long to record, specify how bandwidth is allocated between digital and analog recoding, select which channels to record, and even make the LED your favorite color.
Navigate
When you have billions of data points to display, it is important that getting around in all that data is a zippy experience. Effortlessly zoom in and out with the scroll wheel, and navigate left and right by dragging the data where you want it.
Measure
For basic measurements, just place your mouse near something interesting. The software will figure out the rest and display the relevant measurements. You can show different measurements by right-clicking.
Trigger & Find
The software can start recording automatically when it finds a simple pattern you specify. You can trigger on digital edges and pulses as well as analog voltages and pulses. After you collect your data, you can search for more events this way too.
SPI and I2C
Most digital communication uses a particular protocol that specifies how information is transferred. The Logic software has protocol analyzers that can automatically decode SPI, I2C, serial, 1-Wire, CAN, UNI/O, I2S/PCM, MP Mode, Manchester, Modbus, DMX-512, Parallel, JTAG, LIN, Atmel SWI, MDIO, SWD, LCD HD44780, BiSS C, HDLC, HDMI CEC, PS/2, USB 1.1, Midi – or create your own with the SDK.
Search
Once you have decoded your data with a protocol analyzer, you can search through all these decoded results by just typing what you are looking for – the software will jump right to the spot where it happened.
Annotate
In the software, you can add unlimited bookmarks, which remember what you were looking at; timing markers, which can measure the time between events; and measurements, which annotate the waveform with parameters like width, frequency, RMS voltage and duty cycle.
Save and share
Once you’ve annotated your data, you can easily save it for later review. You can even save it in the cloud to send to colleagues or post online!
Export
Sometimes you will need to do something pretty custom with your data, so you’ll be happy to know it is easy to export it in a variety of formats, including a text csv file or Matlab m file.
Automate
If you need to automate the Logic software, you can control everything over a simple TCP socket using virtually any programming language.
