Instrument Terminology
Refer to the following list for definitions of common PXIe-5831 instrument terms used throughout this document.
Term | Definition |
---|---|
IF IN/OUT Ports | Refers to the IF IN/OUT 0 and IF IN/OUT 1 connectors on the PXIe-3622 front panel for intermediate frequency (IF) signals. |
TRX Ports | Refers to the DIRECT TRX PORTS or SWITCHED TRX PORTS on the mmRH-5582 front panel for RF signals. |
DIRECT TRX PORTS |
RF connectors 0, 1, or 8 on mmRH-5582 modules labeled with DIRECT TRX PORTS. |
SWITCHED TRX PORTS |
RF connectors 0 through 7 or 0 through 15 on mmRH-5582 modules labeled with SWITCHED TRX PORTS. |
LO1 | Refers to the local oscillator responsible for the up and down conversion between IF and mmWave frequencies. |
LO2 | Refers to the local oscillator internal to the PXIe-3622 responsible for the up and down conversion between baseband and IF. |
Onboard |
Refers to the value of the LO Source property and changes purpose depending on the designated LO and instrument configuration. A value of Onboard configures the hardware as follows: |
Secondary |
Refers to the value of the LO Source property for LO1 in the PXIe-5831 IF and mmWave instrument configuration. The value of Secondary sets the source of LO1 to the internal PXIe-3622 synthesizers. This setting optimizes frequency settling time, but may worsen phase noise. NI recommends using this setting when LO sharing and speed optimization for spectral scanning is preferred. |
Offset Mode is Automatic |
Refers to the NI-RFSADownconverter Frequency Offset Mode property or NI-RFSGUpconverter Frequency Offset Mode property set to Automatic. The PXIe-5831 contains 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 enable low IF mode when the signal bandwidth is small enough to allow it. Automatic is the default value. NI recommends keeping offset mode set to the default value. |
Offset Mode is Enabled |
Refers to the NI-RFSADownconverter Frequency Offset Mode property or NI-RFSGUpconverter Frequency Offset Mode property set to Enabled. The PXIe-5831 contains 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-RFSADownconverter Frequency Offset Mode property or NI-RFSGUpconverter Frequency Offset Mode property set to User-Defined. The PXIe-5831 contains a direct conversion architecture. Offset Mode set to User-Defined allows the instrument to operate with maximum instantaneous bandwidth. By default, the offset is selected to maximize the available instantaneous bandwidth. |
dBr |
For receivers, dBr refers to the power of a received signal with respect to the instrument's configured reference level. For example, if the reference level is set to -10 dBm but the received tone is -7 dBr, the actual power of the received CW is -17 dBm. For transmitters, dBr refers to the generated power of a CW with respect to the instrument's peak power setting. For example, with a peak power level setting of +5 dBm and a -3 dBr setting, the power of the transmitted CW is +2 dBm. |

Note LO1 Frequency Tuning Time consists of the PXIe-5653 Lock Time + PXIe-5831
(LO1) Settling Time to Required Accuracy. The PXIe-5653 Lock Time is dependent on the RF Center Frequency (CF)
frequency step change from initial frequency to final frequency. The relationship
between the CF and the PXIe-5653 frequency is governed
by the equation: F_PXIe-5653 =
(FCF + FIF)/8. FIF is determined by the CF. For
CF = 22.5 GHz to 31.3
GHz, FIF = 17.8 GHz; CF = >31.3 GHz to 40
GHz, FIF = 12 GHz; CF = >40 GHz to 44 GHz,
FIF = 9 GHz For example, for a CF step
change from 28 GHz to 39
GHz, first calculate the equivalent FPXIe-5653 for 28 GHz, which is 5.725 GHz, then the equivalent CF frequency for 39 GHz, which is 6.375
GHz. The PXIe-5653 step size is 6.375 GHz - 5.725 GHz
= 650 MHz. The corresponding PXIe-5653 maximum frequency lock time is 10 ms.

37 GHz to 40 GHz | -80 | -47 | -37 |
>40 GHz to 44 GHz | -80 | -60 | -48 |
Conditions: 23 °C; peak output power is set to within -40 dBm to the RF output maximum leveled power specification for direct and switched TRX ports. LO1 x 2 refers to out-of-band leakage where an LO1 harmonic product appears at the TRX port output as a function of the configured peak power level (hence dBr units), and upconverter center frequency (UCF). The relationship between the UCF frequency and the LO1 x 2 frequency is governed by the equation: FLO1x2 =(FUCF+FIF)/2. FIF is determined by the UCF. For UCF = 22.5 GHz to 31.3 GHz, FIF = 17.8 GHz; UCF > 31.3 GHz to 40 GHz, FIF = 12 GHz; UCF >40.0 GHz to 44 GHz, FIF = 9 GHz. In the frequency range 22.5 GHz to 31.3 GHz, the minimum frequency for FLO1x2 is when CF = 22.5 GHz and here FLO1x2 = 20.15 GHz; the maximum frequency for FLO1X2 is when CF = 31.3 GHz and there FLO1x2 = 24.55 GHz. In all cases, LO1x2 is out-of-band. The in-band residual spurs are a function of the transmit tone power (hence dBc units) and are measured to within the instantaneous 1 GHz bandwidth. This does not include carrier leakage and residual image. The out-of-band spur numbers refer to spurs that are offset from the upconverter center frequency between 500 MHz to 5 GHz away, but does not include the LO1 x 2. These spurs are a function of the transmit tone power and hence have dBc units. |

Appendix A: PXIe-5653 LO1 Single Sideband Phase Noise
Appendix B: PXIe-3622 Single Sideband Phase Noise
1 Frequency range refers to the range of upconverter or downconverter center frequencies. The actual frequency coverage extends beyond the upconverter or downconverter frequency by up to half of the frequency bandwidth.
2 Tuning resolution combines LO step size capability and frequency shift DSP implemented on the FPGA.
3 The worst case LO spurious content degrades for smaller LO step sizes and improves for larger LO step sizes that are multiples of 2 MHz and 10 MHz.
4 LO step size can be set using the driver software.
5 Frequency settling refers to the time it takes the frequency to settle once the hardware receives the frequency change. The additional time due to software-initiated frequency changes is not included and varies by computer.
6 LO1 LO Source property is set to Onboard.
7 Average output power ≥ -40 dBm.
8 Refers to the time it takes to switch between two analog gain states with frequency unchanged once the hardware receives the amplitude change. The additional time due to software-initiated amplitude changes is not included and varies by computer. When changing frequencies, reconfiguration time is dominated by the frequency settling. Refer to Frequency Settling Time for more information.
9 Average output power ≥ -40 dBm.
10 Does not show LO1 x 2, RF output residual LO leakage and RF output residual sideband image.
11 The maximum offset is limited to within the equalized bandwidth of the referenced downconverter center frequency.
12 dBr is relative to the full scale of the configured reference level.
13 Specification is applied to -30 dBm to 0 dBm reference level.
14 Typical is applied to -30 dBm to +30 dBm reference level.
15 dBr is relative to the full scale of the configured RF reference level.
16 Conditions: IF0 loopback to IF1; waveform bandwidth: 80 MHz; waveform PAPR: 10.55 dB; MCS Index: 11; 16 OFDM data symbols; 20 packet averages; Channel Estimation Type: Ch Estimation Ref (Preamble); Upconverter/Downconverter Frequency Offset Mode: Enabled; LO2 LO Source: SG_SA_Shared; Reference Level: Average Power Level + Waveform PAPR; Reference Level Headroom: 0 dB.
17 EVM shown is the average of RF output power levels including -24 dBm to 0 dBm.
18 All measurements are taken in loopback from IF0 output to IF1 input (generator and analyzer combined performance) on the front panel representing effects from both IF Out and IF IN except IF OUT EVM in the figure titled WLAN 802.11ax 80 MHz RMS EVM Versus Average Power (Loopback vs IF Out EVM), Measured, which shows only the IF OUT effects (generator only performance). Standard: 802.11ax, MCS:11 . Equalization = Preamble only. Local Oscillators: Shared.
19 Noise Compensated refers to measurements taken while compensating for receiver noise. Return loss for DUT is 6 dB or better.
