These specifications apply to the PXIe-5654 RF Analog Signal Generator with up to 10 GHz or 20 GHz frequency and the PXIe-5696 Amplitude Extender.

When not otherwise specified, these specifications refer to both the PXIe-5654 and the PXIe-5654 with PXIe-5696 system.

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

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

Minimum or maximum specifications are warranted under the following conditions unless otherwise noted.

Over ambient temperature ranges of 0 °C to 55 °C
30 minutes warm-up time
Calibration cycle maintained
Chassis fan speed set to High
NI-RFSG instrument driver used

Notice Do not disconnect the cable that connects RF AMP OUT to ATTN IN. Removing the cable from or tampering with the RF AMP OUT or ATTN IN front panel connectors voids the product calibration, and specifications are no longer warranted.

Typical specifications are valid under the following condition unless otherwise noted.

Over ambient temperature ranges of 23 °C± 5 °C
