2.7 GHz RF Signal Analyzer
Ultrahigh-Stability Timebase
centered at 900 MHz, the rate at which you store samples can be as
low as 250 kS/s.
The PXI-5660 offers an extremely stable timebase with frequency
stability of 20 ppb and frequency accuracy of 50 ppb, making it useful
for a range of automation applications.
Calibration
National Instruments calibrates the amplitude accuracy of the analog
input of the downconverter and digitizer modules. Temperature
variations are calibrated and corrected during normal operation, resulting
in very high stability and repeatability. The modules are shipped with
NIST-traceable and ISO-9002-certified calibration certificates.
Visit ni.com/calibration for more information about calibration services.
Accuracy
The noise and distortion characteristics of the PXI-5660 are stable and
repeatable over time and a wide range of temperature. For example,
with a 1 MHz measurement bandwidth, a -10 dBm signal has a
repeatability of less than 0.1 dB, with a resolution bandwidth (RBW) of
1 kHz and number of averages equal to 10. The PXI-5660 uses a software
compensation method that reduces amplitude error to less than 0.2 dB
over a 20 °C change.

higher speeds – up to 10 times faster – than

Clock Generation and Triggering
The 10 MHz reference clock on the PXI-5660 can synchronize to any one
of three sources – the onboard high-precision OCXO reference clock, an
external reference clock, or the PXI backplane. Using the PXI backplane,
you can synchronize two or more PXI-5660 signal analyzers with each
other and other PXI modules without using cables. You can synchronize
the PXI-5660 to an external source using front-panel connectors. It can
import and export TTL triggers from the PXI trigger bus, the PXI star
trigger line, or the front-panel SMB connector. The PXI trigger bus greatly
simplifies synchronizing RF measurements with other PXI modules such
as digital multimeters, audio analyzers, and machine vision modules.

With the digital downconversion (DDC) functionality of the PXI-5660,
you can acquire narrowband signals at much less than the full
digitization rate. By downconverting channels of up to 1.25 MHz
bandwidth to baseband, the PXI-5660 dramatically reduces the
sampling rate necessary to acquire these signals. This feature results in
dramatic throughput improvements for narrowband applications. For
example, if you want to acquire a signal with a 200 kHz bandwidth
