 When developing or examining any electronic devices, it is often needed to measure parameters of different signals and interpret them. To solve these problems several devices are necessary: oscilloscope, spectrum analyzer, logger, logical analyzer/generator. Each device often requires a separate interface slot and has a special power supply that is also a negative factor.
Usually, professional measurement equipment is too expensive not only for radio-amateurs, but also for large enterprises. We created IRIS USB-oscilloscope - a compact device that combines all the necessary functions. As original developers of this device we can set relatively low prices. Our oscilloscope is affordable for every radio-amateur, in the meantime, it requires little place and is reliable both for amateur and professional measurements. IRIS USB-oscilloscope modes:
- Double-channel oscilloscope: marker measurements, synchronization (absolute, differential, external) and a regulated pretrigger, signal voltage and frequency measurements, filtration. - Double-channel spectrum analyzer: marker measurements, non-linear distortion coefficient measurements, various window functions, filtration. - Double-channel logger: marker measurements, the possibility of adding up to 99 markers with comments, changing minimum, maximum and average voltage at each channel, recording a signal for several tens of hours. - 16(8)-channel logical analyzer: marker measurements, synchronization (by front, by mask), and regulated pretrigger, external timing (synchronization), missing out the set number of impulses, search of set logical combination/front, UART, SPI, I2C, 1-Wire interfaces decoding. - 8-channel logical generator: tabular definition of a signal or direct creation of time diagrams at the screen by mouse. - Accumulator charge/discharge and UART, SPI, I2C, 1-Wire hardware maintenance functions are being developed.
Moreover, IRIS allows:
- adding comments to each measurement, comments are stored in the same file as the measurement results; - saving all the measurement results as vector or bitmap drawing for further import to the other programs or as a data file for analysis; - printing all the measurement results with external printer; - copying all the measurement results to the buffer; - setting events and assigning sounds to them; - calculating various digital filters and carrying out analogue signal filtration; - smoothing the oscilloscope time diagrams; - displaying statistics at all the channels of logical analyzer and generator; - changing interface language; - upgrading the firmware via USB that allows adding custom-built functions.
