An NI 5102 Series Devices feature two analog input channels with extensive functionality. Each channel has 15 MHz of analog input bandwidth. With software selectable attenuation, you can achieve an input voltage range of ±50 mV to ±5 V. Attenuating probes can extend the voltage range to ±50 V. Software-selectable AC or DC coupling further increases the signal measurement capability.

NI 5102 devices use a pair of 20 MS/s, 8-bit flash ADCs to digitize the input signals. The real-time sampling rate ranges from 20 MS/s down to 1 kS/s. For repetitive signals, you can use random-interleaved sampling (RIS) to extend the effective sampling rate to 1 GS/s.

An NI 5102 has 663,000 samples of onboard acquisition memory. Data is acquired into the onboard memory before being transferred to the host PC memory. Both the PCI-5102 and the PXI-5102 can transfer acquisitions samples to host memory in real time. These devices can acquire a maximum 16 million samples if your system has at least 48 MB free. On the AT-5102, PCMCIA-5102, and USB-5102, data transferof up to 663,000 samples takes place after the acquisition ends.

The NI 5102 devices are equipped with sophisticated triggering options, such as programmable trigger thresholds, hysteresis values, trigger holdoff, and bilevel triggering on input channels as well as on a dedicated trigger channel. An NI 5102 also has two TTL/CMOS digital triggers for synchronizing multiple devices.
