    • 1 The modulation bandwidth specification assumes the frequency range is between 85 MHz and 6.6 GHz. For example, 100 MHz bandwidth can be achieved at a frequency of 135 MHz but not 85 MHz.

    2 The frequency settling time specification only includes frequency settling, and it excludes any residual amplitude settling that may occur as a result of large frequency changes. Driver and operating system timing can affect transition times. This specification applies when using RF list mode.

    3 Frequency steps that span the full range of a voltage-controlled oscillator (VCO) require more settling time than steps that remain close together within one VCO or steps that switch between VCOs. The maximum specification covers this worst-case frequency settling time.

    4 Subharmonics are 0.5× the output frequency.

    5 Non-integer harmonics are 1.5× the output frequency.

    6 Assumptions include using an Internal Sample Clock and High Resolution onboard Sample Clock mode. Desired sample rate ranges do not include the first point. A desired sample rate of 50 MS/s yields 8× total interpolation.

    7 If your interpolated sample rate falls within an undesirable band, use the Modulation Toolkit to provide fractional resampling that adjusts the sample rate to achieve better rejection.

    8 Calculated from sync response and typical filter rejection for the PXIe-5450/5451. Refer to the PXIe-5450 Specifications or PXIe-5451 Specifications for more information about the expected performance of the PXIe-5450/5451.

    9 Measured with a test signal at a baseband frequency of 1 MHz. To achieve optimum performance, add a typical wait period of 1 s when crossing a carrier frequency of 3.5 GHz that is increasing or decreasing in frequency.

    10 To achieve optimum performance, add a typical wait period of 1 s when crossing a carrier frequency of 3.5 GHz that is increasing or decreasing in frequency.

    11 Maximum output represents saturated CW power.

    12 The NI-RFSG instrument driver waits long enough for a typical device to settle within 0.5 dB.

    13 Power level accuracy is specified as a CW tone at 1 MHz offset from the carrier frequency. Specifications apply if the device temperature is within 5 °C of the temperature at self-calibration.

    14 Represents saturated CW power.

    15 The LO input has filters that must achieve optimum settling to meet specifications. The LO power must be settled to within 0.5 dB to meet specifications.

    16 The noise figure specifications are for a calibrated output gain of 0 dB.

    17 The limit on the LO output relay is 13 dBm when LO OUT is enabled.

    18 The PXIe-5673E is calibrated for a 0 dBm LO output level. Connect a 50 Ω terminator to the PXIe-5611 LO OUT front panel connector when the LO OUT front panel connector is not in use.

    19 All measurements were made with an PXIe-5673E and PXIe-5663E that were not phase-locked together. Number of symbols=1,250 pseudorandom bit sequence (PRBS) at -30 dBm for all measurements. No equalization in receiver demodulation.
