Application and Technology
You can use an NI PXIe-5665 as either a spectrum analyzer or vector signal analyzer with NI LabVIEW or LabWindows™/CVI software. In addition, you can use the NI PXIe-5665 with the NI Modulation Toolkit for LabVIEW to analyze custom and standard modulation formats.
When combined with NI or third-party analysis toolkits, the NI PXIe-5665 can perform measurements for a broad range of communications standards such as GSM, EDGE, WCDMA, WiMAX, LTE, Bluetooth, WLAN, DVB-C/H/T, ATSC, and MediaFLO. Because all measurements are software-defined, you can simply reconfigure the measurements using standard specific toolkits. With these toolkits, the NI PXIe-5665 provides a low-cost solution to high-performance RF measurements.

Table 1. Comparison of NI Vector Signal Analyzers
Industry-Leading Accuracy and Noise Floor (High-Performance RF Measurements)
The NI PXIe-5665 offers phase noise of -129 dBc/Hz (10 kHz offset at an 800 MHz carrier frequency) and an average noise level of up to -165 dBm/Hz at a 1 GHz carrier frequency, which enables high-accuracy spectral and I/Q measurements. A 16-bit ADC, a high-performance RF front end, and the three-stage architecture provide industry-leading noise floors and spurious-free dynamic range (SFDR).
Figure 1. Phase Noise
With the high-performance NI PXIe-5665, you can test products and standards such as LTE and WCDMA to their full capabilities. The images below show adjacent channel power ratio (ACPR) and error vector magnitude (EVM) measurements on WCDMA and LTE standards, respectively.

Architecture
The three-stage topology of the NI PXIe-5665 provides image rejection of the RF input signal with no ambiguity of the displayed signal. This architecture makes the NI PXIe-5665 ideal for high-accuracy measurements and low noise floors.
Figure 4. Block Diagram of an NI PXIe-5665
Figure 4 shows the NI PXIe-5603 downconverter, which upconverts the RF to a higher intermediate frequency and then downconverts it to a frequency that you can digitize for processing. Image rejection is achieved with a lowpass filter (LPF) that limits the RF signal at the input of the first mixer.
A low phase noise LO is supplied by the NI PXIe-5653, which is shown at the bottom of Figure 1. You can use the NI PXIe-5603 LO outputs to daisy chain multiple downconverters with a single LO source. Using the same LO source is helpful for phase-coherent signal acquisition applications such as multiple input, multiple output (MIMO) systems.
Fast Measurement Speed
Using software-defined measurements in the NI LabVIEW graphical development environment with an NI PXIe-5665, you can perform common spectral and modulation measurements up to 30 times faster than traditional instruments.
You can also perform common spectrum analysis measurements quickly due to the processing power of multicore CPUs. For example, you can perform a 50 MHz spectrum sweep in 6 ms with an NI PXIe-8106 embedded controller (30 kHz RBW). While actual performance is system dependent, Figure 5 shows the relationship between measurement time and resolution bandwidth (RBW).
Figure 5. Measurement Time Versus Resolution Bandwidth for Spans of 10, 25, and 50 MHz
RF List Mode
The NI PXIe-5665 features RF list mode support for fast and deterministic RF configuration changes. You supply a configuration list, and the RF modules proceed through the list without additional interaction with the host system and driver. This makes the configuration changes deterministic. Figure 3 shows this determinism with a single tone at 1 GHz stepping through six power levels in 7 dB steps starting with -10 dBm and ending with -45 dBm and a 500 μs dwell time specified for each step.
Figure 6. Deterministic 500 μs Power Steps Using the NI PXIe-5665 and RF List Mode
You can use the NI PXIe-5665 in both open- and closed-loop scenarios to specify the source for the configuration trigger that advances from one configuration to the next. In an open-loop situation, the NI PXIe-5665 advances through the list based on a user-defined time specification for each step. The closed-loop scenario relies on an external trigger that may be provided by the DUT to advance through the RF configuration list.
RF Record and Playback
You can combine an NI PXIe-5665 RF vector signal analyzer with a PXI RF vector signal generator for record and playback applications. In this application, you use an NI PXIe-5665 to continuously record an RF signal as a file on a redundant array of inexpensive disks (RAID) volume. Then you use an RF vector signal generator to stream the recorded waveform from disk. With a 2 TB RAID volume, an NI PXIe-5665 can be used to stream 50 MHz of RF bandwidth continuously to disk for more than 1.5 hours.
Because of the PCI Express data bus on the vector signal analyzer, you can also use multiple analyzers to stream data to disk. With more than 1 GB/s of total system bandwidth, you can stream more than 100 MHz continuously to disk using multiple analyzers.
Peer-to-Peer Streaming
With NI peer-to-peer data streaming technology, you can continuously transfer data to and from vector signal analyzers and vector signal generators at rates greater than 800 MB/s with minimal latency. High-performance data switches on NI PXI Express chassis offer high-bandwidth communication, while routing data from one module directly to another (without transferring data through the host controller) minimizes the latency of the transfer. Peer-to-peer transfers are supported between multiple PXI Express NI FlexRIO field-programmable gate array (FPGA) modules and between select NI PXI Express digitizers and PXI Express NI FlexRIO FPGA modules.
Flexible Software
Programmed with the NI-RFSA instrument driver, NI PXIe-5665 RF vector signal analyzers can be used in a variety of applications. The driver enables both high-level and low-level control of a variety of instrument settings. Figure 7 features a simple LabVIEW example showing basic spectrum acquisition.
Figure 7. NI LabVIEW Example for Spectrum Sweep
The NI-RFSA driver includes an out-of-the-box soft front panel, which is shown in Figure 8.
Figure 8. NI-RFSA Soft Front Panel
The NI PXIe-5665 is shipped with two NI toolkits in addition to the NI-RFSA driver, the NI Modulation Toolkit and the NI Spectral Measurements Toolkit.
With the Spectral Measurements Toolkit for LabVIEW and LabWindows/CVI, you can perform common measurements such as power spectrum, peak power and frequency, in-band power, adjacent channel power, and occupied bandwidth. In addition, the NI Modulation Toolkit for LabVIEW provides tools for vector signal analyzers. With this toolkit, you can perform measurements on a wide variety of modulated signals including schemes such as AM, FM, ASK, FSK, PSK, CPM, MSK, and QAM. In addition, the toolkit computes modulation accuracy measurements such as EVM, MER, rho, and others.
Phase-Coherent Analysis
The flexibility of the NI PXIe-5665 module enables multiple instruments to share a common start trigger, a reference clock, and even an LO. As a result, you can synchronize at least four NI PXIe-5665 RF vector signal analyzers for phase-coherent acquisition.

**Fast Configuration refers to setting the LO YIG Main Coil Drive property to Fast at an accuracy of 1.0 × 10–6 of final frequency. Normal Configuration refers to setting the LO YIG Main Coil Drive property to Normal at an accuracy of 0.1 × 10–6 of final frequency. † Tuning times refer to tuning within a single band, for example, tuning within 0 Hz to 3.6 GHz or within 3.6 GHz to 7.5 GHz. The tuning times for tuning within the 7.5 GHz to 14 GHz band are lower than if the frequency spans multiple frequency bands. If your application uses the NI 5665 14 GHz VSA with the preselector enabled, add the preselector tuning times to the tuning times listed in this table |

| * When used in a vector signal analyzer (VSA) system, the nominal specification for the VSA improves significantly from this value because the VSA uses the other LO’s as well, and not just a single LO. Phase noise of other LO’s is correlated to phase noise on LO1 at low offsets, which results in improved performance of the VSA system. | ||
