PCI-9527 User’s Manual ADLINK Technology Inc. Copyright 2008 Inspect the carton and packaging for damage. Shipping and handling could cause damage to the equipment inside. Make sure that the equipment and its associated components have no damage before installing. CAUTION: 14 The equipment must be protected from static discharge and physical shock. Never remove any of the socketed parts except at a static-free workstation.
ADLINK Technology Inc. Copyright 2008 PCI-9527 User’s Manual 2.2 Package Contents Before continuing, check the package contents for any damage and check if the following items are included in the packaging: PCI-9524 Multi-function Data Acquisition Card ADLINK All-in-one Compact Disc Software Installation Guide PCI-9524 User’s Manual If any of these items are missing or damaged, contact the dealer from whom you purchased the product.

ADLINK Technology Inc. Copyright 2008 PCI-9527 User’s Manual 2.4 Installing the Module To install the card: 1. Turn off the system/chassis and disconnect the power plug from the power source. 2. Remove the system/chassis cover. 3. Select the PCI slot that you intend to use, then remove the bracket opposite the slot, if any. 4. Align the card connectors (golden fingers) with the slot, then press the card firmly until the card is completely seated on the slot. 5. Secure the card to the chassis with a screw.

For ground-reference signal source, user should configure analog input as differential.
ADLINK Technology Inc. Copyright 2008 2.5.3 PCI-9527 User’s Manual Analog Output Connection If the DUT inputs are ground-referenced, the differential output mode can be used for the elimination of measuring errors which caused by ground loops. If the DUT inputs are in a floating system (ex. a floating earphone), setting to pseudo-differential output mode will provide a reference ground connected to the positive output of the BNC through a 50 Ω resistor.

ADLINK Technology Inc. Copyright 2010 PCI-9527 User’s Manual Input Coupling, DC Coupling or AC Coupling The input coupling can be AC or DC. When you select DC coupling, the DC offset present in the input signal is pass to ADC. Use the DC coupling configuration if the signal source has a small amount of offset voltage or if the DC content of the signal is important. When you select AC coupling, the DC offset present in the input signal is removed.
PCI-9527 User’s Manual 3.2.2 ADLINK Technology Inc. Copyright 2010 Input Range and Data Format When using an A/D converter, users should first know about the properties of the signal to be measured. Users can decide which channel to use and how to connect the signals to the card. Please refer to section 2.5 for signal connections. The A/D acquisition is initiated by a trigger source; users must decide how to trigger the A/D conversion. The data acquisition will start once a trigger condition is matched.
ADLINK Technology Inc. Copyright 2010 3.2.3 PCI-9527 User’s Manual ADC and Analog Input Filter ADC (Analog-to-Digital Converter) The ADCs on PCI-9527 are sigma-delta ADC which is very suitable for vibration, audio and acoustic measurement. The analog side of sigma-delta ADC is a 1-bit ADC. On digital side, it performs oversampling, noise shaping and digital filtering. For example, if desired sampling rate is 108KS/s, each ADC samples input signal at 6.912MS/s, 64 times the sampling rate. The 1-bit 6.
PCI-9527 User’s Manual 3.2.4 ADLINK Technology Inc. Copyright 2010 FIFO and DMA Transfer For Analog Input FIFO There is only one FIFO implemented on PCI-9527 for analog input data storage. The FIFO depth is 4096 samples. The 4096 samples are shared for both AI channels. When user enables only one AI channel, the 4096-sample-FIFO is used for one channel data storage. When user enables two AI channels, the 4096-sample-FIFO shares for both channel.

PCI-9527 User’s Manual ADLINK Technology Inc. Copyright 2010 Analog Front-End Filter Each channel has a 3-pole low pass filter. The cutoff frequency is set at 110 KHz to limit the bandwidth of the signal path. This will mostly reject out of band images and noise. 3.3.4 FIFO and DMA Transfer For Analog Output FIFO There are two FIFOs implemented on PCI-9527 for the analog output function. Each FIFO depth is 2048 samples.
ADLINK Technology Inc. Copyright 2010 PCI-9527 User’s Manual 3.4 Trigger Source and Trigger Mode This section describes information about triggering theory of operation. In PCI-9527, the operation of AI and AO share the same trigger source. Therefore, when user enables AI and AO operation simultaneously, the trigger signal is valid only when AI and AO are ready to receive trigger signal. For more detail in programming the PCI-9527, please refer to software operation manual. 3.4.
PCI-9527 User’s Manual ADLINK Technology Inc. Copyright 2010 External Digital Trigger An external digital trigger occurs when a TTL rising edge or a falling edge is detected at the SMB connector on the front panel. As illustrated in Figure x-x, the trigger polarity can be selected by software. Note that the signal level of the external digital trigger signal should be TTL compatible, and the minimum pulse width is 25 ns.
ADLINK Technology Inc. Copyright 2010 3.4.2 PCI-9527 User’s Manual Trigger Mode There are two trigger modes working with trigger sources to initiate different data acquisition timing when a trigger event occurs. The following trigger mode descriptions are applied to analog input and analog output functions.
PCI-9527 User’s Manual ADLINK Technology Inc. Copyright 2010 Delay Trigger Mode If user configures the trigger mode as delay trigger, user can specify a delay time from when the trigger event asserts to the beginning of the acquisition and waveform generation. The operation is illustrated below. The delay time is specified by a 32-bit counter value and the counter is clocking based on the PCI clock.

The timebase clock frequency is much higher than the sample rate and is produced from a DDS chip.
PCI-9527 User’s Manual ADLINK Technology Inc. Copyright 2010 3.5.3 Timing Constraint When AI and AO Enabled Simultaneously As users can see in the section 3.5.1, the ADC and DAC shares the same Timebase source, i.e. the output of DDS clock. When users enable the operation of ADC and DAC at the same time, there are constraints that should be kept in mind: 1. The sampling rate of ADC and the update rate of DAC are related.
ADLINK Technology Inc. Copyright 2010 3.5.4 PCI-9527 User’s Manual Filter Delay in ADC and DAC The filter delay indicates the time required fro data to propagate through a converter. Both AI and AO channels have filter delay due to the filter circuitry and the architecture of the converter. Following tables show the filter delay in ADC and DAC.

ADLINK Technology Inc. Copyright 2010 4 PCI-9527 User’s Manual Calibration This chapter introduces the calibration process to minimize analog input measurement errors and analog output errors. 4.1 Calibration Constant The PCI-9527 is factory calibrated before shipment by writing the associated calibration constants to the onboard EEPROM. Every time the system boot up, the PCI-9527 driver will load these calibration constants that minimize the error in analog input path and analog output circuit.
PCI-9527 User’s Manual ADLINK Technology Inc. Copyright 2010 4.2 Auto-Calibration Because errors in measurement and outputs will vary with time and temperature, it is recommended to re-calibration when the card is installed in the user’s environment. The auto-calibration can measure and minimize errors without external signal connections, reference voltages, or measurement devices. The PCI-9527 has an on-board calibration reference to ensure the accuracy of auto-calibration.
ADLINK Technology Inc. Copyright 2008 5 PCI-9527 User’s Manual Calibration This chapter introduces the calibration process to minimize AD measurement errors and DA output errors. 5.1 Loading Calibration Constants The PCI-9524 is factory calibrated before shipment by writing the associated calibration constants of TrimDACs firmware to the onboard EEPROM. TrimDACs firmware is the algorithm in the FPGA.
PCI-9527 User’s Manual ADLINK Technology Inc. Copyright 2008 5.2 Auto-calibration By using the auto-calibration feature of PCI-9524, the calibration software can measure and minimize measurement errors without external signal connections, reference voltages, or measurement devices. PCI-9524 has an on-board calibration reference to ensure the accuracy of auto-calibration. The reference voltage is measured on the production line through a digital potentiometer and compensated in the software.
