Antistatic mat The JYTEK PCIe-69834 is electrostatically sensitive and can be easily damaged by static electricity. The module must be handled on a grounded anti-static mat. The operator must wear an anti- static wristband, grounded at the same point as the anti-static mat.
If any of these items are missing or damaged, contact the dealer Do not install or apply power to equipment that is damaged or missing components. Retain the shipping carton and packing materials for inspection. Please contact your JYTEK dealer/ vendor immediately for assistance and obtain authorization before returning any product.

For auto-calibration, internal calibration provides stable and accurate reference voltage to the AI. 3.2.2 Input Range and Data Format Data format of the PCIe-69834 is 2’s complement. …. D15 to D0 bits represent the 16-bit data from ADC (2’s complement)
0.015 mV -0.015 mV Digital Code 0001 0000 FFFF Table 3-3: Input Range Midscale Values 3.2.3 DMA Data Transfer The PCIe-69834, a PCIe Gen 1 X 4 device, is equipped with 80MS/s high sampling rate ADC, generating MByte/second rate. To provide efficient data transfer, a PCI bus-mastering DMA is essential for continuous data streaming, as it helps to achieve full potential PCI Express bus bandwidth.
the maximum DMA data transfer size is 2 MB double words (8 MB bytes); in scatter-gather mode, there is no limitation on DMA data transfer size except the physical storage capacity of the system. Users can also link descriptor nodes circularly to achieve a multi- buffered DMA.
(Master => Slave) (Master <= Slave) Figure 3-3: Trigger Architecture The PCIe-69834 requires a trigger to implement acquisition of data. Configuration of triggers requires identification of trigger source. The PCIe-69834 supports internal software trigger, external digital trigger, and analog trigger.
Post-trigger acquisition is applicable when data is to be collected after the trigger event, as shown. When the operation starts, PCIe-69834 waits for a trigger event. Once the trigger signal is received, acquisition begins. Data is generated from ADC and transferred to system memory continuously.
Figure 3-5: Post-Trigger Acquisition 3.4.2 Delayed Trigger Mode Delayed-trigger acquisition is utilized to postpone data collection after the trigger event, as shown. When the PCIe-69834 receives a trigger event, time delay implemented before commencing acquisition. The delay is specified by a 16-bit...

3.5.1 Internal Sampling Clock The PCIe-69834 internal 80MHz crystal oscillator acts as a sam-pling clock for ADC. 3.5.2 External Reference Clock (PCIe-69834P only) The onboard PLL module allows REF_CLK to act as an external reference clock input, such that when multi-card synchronization...
Figure 3-11: Timebase Architecture 3.6.2 Basic Acquisition Timing The PCIe-69834 commences acquisition upon receipt of a trigger event originating with software command, external digital trigger. The Timebase is a clock provided to the ADC and acquisition engine for essential timing. The Timebase is from an onboard syn-thesizer.

For example, if the scan interval counter is set as 2, the equivalent sampling rate is 80MS/s / 2 = 40MS/s.
Re-Triggering Table 3-4: Counter Parameters and Description 3.7 Synchronizing Multiple Modules The PCIe-69834 provides a dedicated connector as system syn- chronization interface, enabling multiple module synchronization. As shown, bi-directional SSI I/Os provides a flexible connection between modules, allowing one SSI master PCIe-69834 to output SSI trigger signals to other slave modules.For more accurate syn-...

EEPROM. At system boot, the PCIe-69834 driver loads these calibration con-stants, such that analog input path errors are minimized. JYTEK provides a software API for calibrating the PCIe-69834. The onboard EEPROM provides two banks for calibration con- stant storage.
Before initializing auto-calibration, it is recommended to warm up PCIe-69834 least minutes remove connected cables. It is not necessary to manually factor delay into applications, as the PCIe-69834 driver automatically adds the compensation time. NOTE: NOTE: PCIe-69834 Onboard Calibration Source Switch...
