A good frequency response analyzer is a marked by the following features:
- Nominal frequency range of operation
- Swept-sine output to drive circuit under test
- Dual receive channels to measure ratio of signals and phase shift signals
- High noise rejection with selectable bandwidth
- Easy interface to computer for post processing of data
DP-PCI-755 is one such PCI card capable of analyzing the phase-gain characteristics of the system. The system under test is stimulated by user defined waveforms and the acquired response is correlated with the applied stimulus by the on-board DSP processor to study the phase difference and gain.
DP-PCI-755 employs DDS techniques in generating wave shapes. The hardware logics handle starting of waveform at 0º and stopping at 0º as well. Smooth stepping from one frequency to the next is possible under sweep mode.The 16 bit ADC converters promises higher resolution at better scanning rates programmable upto 72KS/s.
The module can be operated under master and slave mode. In master mode, DTFA provides synchronization signals to slave units. In the slave mode, DTFA receives external signal and this supports construction of multi-channel systems.
DP-PCI-755 is ideal for characterization of electro-mechanical systems, electro-hydraulic systems and filters.
The module is supplied with drivers in Windows 2000 and RT Linux.
