PXIe-5841 Specifications

PXIe-5841 Specifications

This specifications document contains specifications for both the PXIe-5841 Vector Signal Transceiver (VST) and the PXIe-5841 when paired with the optional PXIe-5655 local oscillator (LO).

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty. Warranted specifications account for measurement uncertainties, temperature drift, and aging. Warranted specifications are ensured by design or verified during production and calibration.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical specifications describe the performance met by a majority of models.
  • Typical-95 specifications describe the performance met by 95% (≈2σ) of models with a 95% confidence.
  • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.
  • Measured specifications describe the measured performance of a representative model.
Specifications are Warranted unless otherwise noted.

Conditions

All specifications are valid under the following conditions unless otherwise noted.

  • 30 minute warm-up time
  • Self-calibration is performed after the specified warm-up period has completed
  • Calibration cycle is maintained
  • The chassis fan mode is set to Auto when used in a chassis with ≥58 W slot-cooling capability or the fan mode is set to High when used in any other chassis
  • Empty chassis slots contain slot blockers and EMC filler panels to minimize temperature drift and reduce emissions
  • Modules are connected with NI cables as shown in the PXIe-5841 Getting Started Guide
  • RFmx, NI-RFSA, or NI-RFSG instrument driver is used
  • Calibration IP is used properly during the creation of custom FPGA bitfiles

Typical specifications do not include measurement uncertainty and are measured immediately after a device self-calibration is performed.

Unless otherwise noted, specifications assume the PXIe-5841 is configured in the following default mode of operation:
  • Reference Clock source: Onboard
  • RF IN reference level: 0 dBm
  • RF IN preamplifier: AUTO
  • RF OUT power level: 0 dBm
  • LO tuning mode: Fractional
  • LO PLL loop bandwidth: Medium
  • LO step size: 500 kHz
  • LO frequency: 2.4 GHz
  • LO source: Onboard LO
Unless otherwise noted, specifications assume the PXIe-5841 with the PXIe-5655 is configured in the following default mode of operation:
  • Reference Clock source: Onboard (from the PXIe-5655)
  • RF IN reference level: 0 dBm
  • RF IN preamplifier: AUTO
  • RF OUT power level: 0 dBm
  • LO tuning mode: Fractional
  • LO PLL loop bandwidth: Low
  • LO step size: 500 kHz

Warranted specifications are valid over temperature ranges described in the Environmental Characteristics section of this document unless otherwise noted.

Specifications are identical for the PXIe-5841 and the PXIe-5841 with the PXIe-5655 unless otherwise noted.

Common NI Terminology for RF Settings

Refer to the following list for definitions of common NI terms related to software-configured settings for the PXIe-5841 and used throughout this document.

Table 1. Common Terminology Definitions
Term Definition
Center Frequency

Refers to the IQ Carrier Frequency property in NI-RFSA, the Frequency property in NI-RFSG, and the Center Frequency property in RFmx.
Offset Mode is Automatic

Refers to the NI-RFSA Downconverter Frequency Offset Mode property or NI-RFSG Upconverter Frequency Offset Mode property set to Automatic.

The PXIe-5841 uses a direct conversion architecture. Offset Mode allows the instrument to operate in low IF mode, which increases the separation between the signal of interest and the residual sideband image and residual LO leakage power. However, low IF mode limits the available instantaneous bandwidth. A setting of Automatic allows the driver to set Offset Mode to Enabled when the signal bandwidth is configured as small enough to allow it. You can read back the Offset Mode to determine if the driver selected Enabled or User-Defined.

Automatic is the default value. NI recommends keeping Offset Mode set to the default value.
Offset Mode is Enabled

Refers to the NI-RFSA Downconverter Frequency Offset Mode property or NI-RFSG Upconverter Frequency Offset Mode property set to Enabled.

Equivalent to Signal Bandwidth ≤ Maximum Offset Bandwidth.

The PXIe-5841 uses a direct conversion architecture. Offset Mode allows the instrument to operate in low IF mode, which increases the separation between the signal of interest and the residual sideband image and residual LO leakage power.
Offset Mode is User-Defined

Refers to the NI-RFSA Downconverter Frequency Offset Mode property or NI-RFSG Upconverter Frequency Offset Mode property set to User-Defined.

Equivalent to Signal Bandwidth > Maximum Offset Bandwidth.

The PXIe-5841 uses a direct conversion architecture. Offset Mode set to User-Defined allows the instrument to operate with maximum instantaneous bandwidth.
Onboard

Refers to the value of the LO Source property. A value of Onboard configures the hardware to use the PXIe-5841 LO on an associated PXIe-5655 (if present).

Frequency

The following characteristics are common to both RF IN and RF OUT ports.

Frequency range 9 kHz to 6 GHz
