 While developing or examining any electronic devices a radio-amateur often needs to measure the signal parameters or at least to check the input and output signals, record them and, possibly, decode. A number of devices are used to solve these problems: oscilloscope, spectral 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.
As usual, the professional measurement equipment is too expensive not only for a radio-amateur, but as well for the very large enterprises. We created a compact device combining all the necessary functions: IRIS USB-oscilloscope . We are the developers of this device and can set relatively low prices. Our oscilloscope is affordable for every radio-amateur, in the meantime, it requires little place and is reliable for amateur measurements as well as for professional usage IRIS USB-oscilloscope modes:
- Double-channel oscilloscope: marker measurements, synchronization (absolute, differential, external) and a regulated pretrigger, signal voltage and frequency measurement, filtration. - Double-channel spectrum analyzer: marker measurements, non-linear distortion coefficient measurement, various window functions, filtration. - Double-channel logger: marker measurements, the possibility of adding up to 99 markers with comments, changing minimal, maximal and average voltage at each channel, recording the signal during dozens of hours. - 16(8)-channel logical analyzer: marker measurements, synchronization (by slope, by mask), and regulated pretrigger, external timing (synchronization), missing out the set number of impulses, set logical combination / slope search, UART, SPI, I2C, 1-Wire interfaces decoding. - 8-channel logical generator: tabular signal setting or direct creating time diagrams at the screen using mouse - - Accumulator charge / discharge and UART, SPI, I2C, 1-Wire protocols hardware maintenance functions are under construction.
Moreover, IRIS allows:
- adding comments to each measurement and recording them to the file with measurement results; - saving all measurement results as vector or bitmap drawing for the further import to the other programs or as a data file for the further analysis; - printing all the measurement results with external printer; - copying all the measurement results to the buffer; - setting events and sound schemes; - calculating various digital filters and carry out analogue signal filtration; - evening the oscilloscope time diagrams; - display statistics at all the channels of logical analyzer and generator; - change interface language; - upgrade the firmware via USB that allows adding any optional functions required.
