MEASUREMENTS: The menu can be found under the MEAS button. Here you can select up to 4
measured values in total, then provide the corresponding values.
In the Operator field select the desired measurement and then set the Signal from which channel the
value should be taken. One click on DONE shows the value in the bottom of the channel settings. You
may choose among the following:

P2P: The difference between the lowest and the highest measured voltage value.

MEAN: The calculated average of the signal.

MAX: The highest measured voltage value.

MIN: The lowest measured voltage value.

RMS: The calculated RMS (root mean square) of the signal.

DUTY CYCLE: The Signal’s duty cycle (ratio of the pulse duration and period length).

PERIOD: Displays the period length, the time length of a vibration.

FREQ: The frequency of the signal.

3.2. Spectrum Analyzer
This application will turn your HAMlab board into a 2-channel DFT Spectrum Analyzer. It is the perfect
tool for educators, students, makers, hobbyists and professionals seeking affordable, highly functional
test and measurement equipment.
The DFT Spectrum analyzer application enables a quick and powerful spectrum analysis using a DFT
algorithm. Frequency span is form DC up to 62.5MHz where the frequency range can be arbitrarily
selected. You can easily measure the quality of your signals, signal harmonics, spurious and power.
Instrument HAMlab 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). The elements on the DFT Spectrum
analyzer application are arranged logically and offer a familiar user interface.
The graphical interface is divided into 4 main areas:
Run/Stop and Export button: The “Run/Stop” button is used to start and stop measurements. With the
“Export” button you can select in which format you want to download the measured data (plotted
spectrum). Two formats are available: .png and .csv.
