The measurement complex is designed for simultaneous data measurement and study of the form of several electric signals, frequencies of which range from 0 to 60 kHz, amplitudes range from 0 to ±750 V. It can be used to receive special form signals (sinusoidal, triangular, rectangular, etc.).
The measurement complex includes a computer, the measurement complex proper with generator and software, required for the work of the complex. The PC is required for exchanging information with the measurement complex and the generator, for the analysis of the obtained data in real time mode.
The measurement complex consists of digital storage oscillograph with three isolated ports. Each port of the oscillograph has seven 12 bit measuring channels for different measurement ranges, five of which are designed to measure voltage (±400V, ±50V), and two – to measure current (±5A, ±2A).
The generator is based on built-in DAC and allows forming the following signals:
- constant signal;
- sinusoidal signal;
- triangular signal;
- rectangular signal;
- arbitrary signal.
The choice of a signal form and parameters can be made at PC using its software. Power supply of the complex is from computer through USB.
The stand allows doing the following laboratory works:
- To plot up to 21 measuring channels on the same axis with individual setup of vertical parameters for each channel and common setup of horizontal parameters for all channels.
- To compare measured signals.
- To make real time mathematical calculations of measured parameters and display them.
- To display function, momentary and average signal value.
- To measure signal frequency.
- To plot Lissajous figures for any of the two measuring channels.
- To analyze spectrum of any of the measuring channels used.
- To measure the signal frequency of any signal used.
- To calculate active and reactive constituents of power, total power, power coefficient.
- To save data array from buffer for further analysis.
- To export oscillograms to graph formats JPG, BMB.
- To set DAC values while forming constant signal, sinusoidal, triangular and rectangular signals.
- The software includes built-in function of verification of oscillograph channels. It also provides for profiling function.
