HAMlab, Release 1.0

AXIS CONTROLS

Hori/- buttons are used to select the span of the X (frequency) axis (zooming in/out). The ver-
tical +/- buttons change the Y (amplitude)-axis range. Reset button when selected reset frequency and
amplitude span do default values.

Logic Analizer

The Logic Analyzer application enables the representation of the binary states of digital signals. The Logic Analyzer
can both deal with purely binary signals, such as GPIO outputs of the Raspberry Pi or Arduino board, as well as analyze
different bus (I2C, SPI, and UART) and decode the transmitted data. Instrument applications are web-based and do
not require the installation of any native software. Users can access them via a web browser using their smartphone,
tablet or a PC running any popular operating system (MAC, Linux, Windows, Android, and iOS).

HAMlabs Logic Analyzer enables capturing of different logic levels. The graphical user interface of the Logic Ana-
lyzer fits well into the overall design of the HAMlab applications providing the same operating concept. The Logic
Analyzer user interface is shown below.
