NI 5661 RF Vector Signal Analyzer

This section includes information useful about the NI 5661 hardware, including module front panels, theory of operation, signal paths, block diagrams, and calibration information. The NI 5661 is a modular RF vector signal analyzer consisting of two PXI hardware modules:

• NI 5142 — 14 bit, 100 megasample-per-second (MS/s) IF digitizer module with onboard signal processing (OSP)
• NI 5600 — wideband RF downconverter module with input frequencies between 9 kHz and 2.7 GHz.

Note  There is no physical device labeled the "NI PXI-5661." The NI 5661 RF Vector Signal Analyzer is the instrument comprised of the two hardware modules (NI 5600 and NI 5142) and the software included in the kit. Refer to the NI RF Vector Signal Analyzers Getting Started Guide for more information about installing and configuring your hardware.

The NI 5661 has the following characteristics and features:

• 9 kHz to 2.7 GHz frequency range
• 20 MHz real-time bandwidth
• 10 MHz oven-controlled crystal oscillator (OCXO) timebase
  • ±20 ppb frequency stability
  • ±50 ppb frequency accuracy
• >80 dB spurious-free dynamic range
• +30 dBm full signal input range
• Up to 64 MS of onboard waveform memory
• Software for performing frequency-domain and IQ measurements
• Four slots wide PXI/3U Compact PCI form factor

The NI 5661 follows industry-standard Plug and Play specifications for the PXI bus and seamlessly integrates with compliant systems.

Note  Refer to the NI PXI-5661 Specifications document included in the RF Signal Analyzer kit for complete hardware specifications.
