way. The driver automatically generates the requested sampling clock from the fed in reference clock. Star-Hub The Star-Hub is an additional module allowing the phase stable synchroniza- tion of up to 8 boards of a kind in one system. Independent of the number of boards there is no phase delay be- tween all channels. The Star-Hub dis- tributes trigger and clock information between all boards to ensure all con- nected boards are running with the same clock and trigger. All trigger sources can be combined with a logical OR allowing all channels of all cards to be the trigger source at the same time. External Amplifiers For the acquisition of extreme- ly small voltage levels with a high bandwidth a series of ex- ternal amplifiers is available. Each of the one channel am- plifiers is working with a fixed input impedance and allows - depending on the bandwidth - to select different amplifica- tion levels between x10 (20 dB) up to x1000 (60 dB). Us- ing the external amplifiers of the SPA series voltage levels in the uV and mV area can be acquired.

Measured parameters are averaged 20 times to get typical values. Test signal is a pure sine wave generated by a signal generator and a matching bandpass filter. Amplitude is >99% of FSR. SNR and RMS noise parameters may differ depending on the quality of the used PC. SNR = Signal to Noise Ratio, THD = Total Harmonic Distortion, SFDR = Spurious Free Dynamic Range, SINAD = Signal Noise and Dis- tortion, ENOB = Effective Number of Bits.
