Calibration

External Calibration

External calibration corrects the onboard references for gain and offset errors used in self-calibration and adjusts the compensation attenuator. All calibration constants are stored in nonvolatile memory.

Self-Calibration

Self-calibration is done on software command. The calibration corrects for gain, offset, interleaving spurs, and intermodule synchronization errors. Run self-calibration after the specified warm-up time has elapsed and any time the module is power cycled or the PC or controller is restarted or wakes from sleep or hibernation modes. Refer to the NI High-Speed Digitizers Help at ni.com/manuals for more information on when to self-calibrate the device.

Software

Driver Software

Driver support for this device was first available in NI-SCOPE18.6.

NI-SCOPE is an IVI-compliant driver that allows you to configure, control, and calibrate the PXIe-5111. NI-SCOPE provides application programming interfaces for many development environments.

Application Software

NI-SCOPE provides programming interfaces, documentation, and examples for the following application development environments:

  • LabVIEW
  • LabWindows™/CVI™
  • Measurement Studio
  • Microsoft Visual C/C++
  • .NET (C# and VB.NET)

Interactive Soft Front Panel and Configuration

When you install NI-SCOPE on a 64-bit system, you can use InstrumentStudio to monitor, control, and record measurements from the PXIe-5111.

InstrumentStudio is an application that allows you to perform interactive measurements on several different NI device types in a single application.

Interactive control of the PXIe-5111 was first available via InstrumentStudio in NI-SCOPE18.6. InstrumentStudio is included on the NI-SCOPE media.

NI Measurement & Automation Explorer (MAX) also provides interactive configuration and test tools for the PXIe-5111. MAX is included on the driver media.

Synchronization with the NI-TClk API [24]

NI-TClk is an API that enables system synchronization of supported PXI modules in one or more PXI chassis, which you can use with the PXIe-5111 and NI-SCOPE.

NI-TClk uses a shared Reference Clock and triggers to align the Sample Clocks of PXI modules and synchronize the distribution and reception of triggers. These signals are routed through the PXI chassis backplane without external cable connections between PXI modules in the same chassis.

Product Certifications and Declarations

Refer to the product Declaration of Conformity (DoC) for additional regulatory compliance information. To obtain product certifications and the DoC for NI products, visit ni.com/product-certifications, search by model number, and click the appropriate link.

2 Derate above 250 kHz at 20 dB/dec until 2.5 MHz, then derate at 5 dB/dec.

3 Within ±5 °C of self-calibration temperature.

4 Used to calculate errors when the onboard temperature changes more than ±5 °C from the self-calibration temperature.

5 Measured on one channel with test signal applied to another channel and the same range setting on both channels. For 1 MΩ path, specifications are valid for input ranges ≤10 V (Vpk-pk).

6 Normalized to 50 kHz.

7 For input ranges ≤4 V (Vpk-pk) and temperature 0 °C to 30 °C.

8 When used with the NI SP500X passive probe.

9 Excludes ADC interleaving spurs.

10 Input frequencies <100 MHz, input range ≤4 Vpk-pk. -1 dBFS input signal. Includes second through fifth harmonics.

11 Input frequencies <100 MHz. -1 dBFS input signal corrected to FS. 1 kHz resolution bandwidth.

12 Applies to all filter settings and input modes. Verified using a 50 Ω terminator connected to input.

13 Divide by n decimation from 1.5 GS/s. For more information on the sample clock and decimation, refer to the NI High-Speed Digitizers Help.

14 Single channel only.

15 Phase-locked to onboard clock. The default clock is PXI_Clk100. Refer to your chassis specifications for the timebase accuracy of PXI_Clk100.

16 Integrated from 100 Hz to 10 MHz. Includes the effects of converter aperture uncertainty and the clock circuitry jitter. Excludes trigger jitter.

17 Data must exceed each corresponding trigger threshold for at least this minimum duration to ensure analog triggering.

18 1 kHz, 50% duty cycle square wave.

19 When measured with a high-impedance device.

20 When sourcing into a 50 Ω cable or load.

21 Onboard memory is shared among all enabled channels.

22 For 512 MB option. You can exceed this value if you fetch records while acquiring data. For more information, refer to the Enable Records > Memory property in the NI High-Speed Digitizers Help at ni.com/manuals.

23 Warm-up time begins after the chassis and either the controller or PC is powered and NI-SCOPE is loaded.

24 NI-TClk installs with NI-SCOPE.

25 Although you can use NI-TClk to synchronize non-identical modules, these specifications apply only to synchronizing identical modules. Specifications are valid under the following conditions:

  • All modules installed in the same PXI Express chassis
  • NI-TClk used to align the sample clocks of each module
  • All parameters set to identical values for each module
  • Self-calibration completed
  • Ambient temperature within ±1 °C of self-calibration
For other configurations, including multi-chassis systems, contact NI Technical Support at ni.com/support.

26 Manual adjustment is the process of minimizing synchronization jitter and skew by adjusting Trigger Clock (TClk) signals using the instrument driver.

27 Skew is the misalignment between module timing across slots of a chassis and is caused by clock and analog path delay differences.

28 Jitter is the variation in module alignment that can be expected with each call to NI-TClkSynchronize.
