External clock input and output Using a dedicated connector a sampling clock can be fed in from an external system. Additionally it’s also possible to output the in- ternally used sampling clock on a separate connector to synchro- nize external equipment to this clock. Reference clock The option to use a precise external reference clock (normally 10 MHz) is nec- essary to synchronize the instrument for high-quality measurements with external equipment (like a signal source). It’s also possible to enhance the quality of the sampling clock in this way. The driver automatically generates the requested sampling clock from the fed in reference clock. PXIe bus The PXI Express bus (PCI Express eXtension for instrumentation) of- fers a variety of additional normed possibilities for synchronising different components in one system. It is posible to connect several Spectrum cards with each other as well as to connect a Spectrum card with cards of other manufacturers. PXI reference clock The card is able to use the 100 MHz low-jitter reference clock that is supplied by the PXIe system. Enabled by software the PXIe refer- ence clock is fed into the on-board PLL. This feature allows the cards to run with a fixed phase relation. PXI trigger The Spectrum cards support star trigger as well as the PXI trigger bus. Using a simple software commend one or more trigger lines can be used as trigger source. This feature allows the easy setup of OR connected triggers from different cards. 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. Export Versions Special export versions of the products are available that do not fall under export control. Products fall under export control if their spec- ification exceeds certain sampling rates at a given A/D resolution and if the product is shipped into a country where no general ex- port authorization is in place. The export versions of the products have a sampling rate limitation matching the export control list. An upgrade to the faster version is not possible. The sampling rate limitation is in place for both inter- nal and external clock.

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.
