Taking Measurementswith the NI PXI-562xThe NI PXI-5620 is a 64 Ms/s, 14-bit frequency-domain digitizer
moduleoptimized forthe best possible noise and distortionperformance
in a 5 –25 MHz passband. It has a –3 dB front-end bandwidth from
10 kHz to 36 MHz, and is always AC-coupled, meaning it does not admit
DC components of a signal.
TheNI P XI-5621 is a DC-coupled version of the NI PXI-5620, optimized
for a passband of 0–25 MHz. Except for its permanent DC coupling and
widerfront-end bandwidth, the NI PXI-5621 is functionally identical to the
NIPXI-56 20.
Refert o the NI PXI-5620 Specifications and the NI PXI-5621
Specifications documents for NI PXI-562xperformance specifications.
This chapter provides information on installing, connecting signals to,
and acquiring data from the NI 562xmodules.
TheNI 562xfamily of high-speed digitizers has the following features:
•A 14-bit, 64 MS/s analog-to-digital converter(ADC)
•32 or 64 MB deep onboard sample memory
Installing the Software and Hardware
Perform the following steps to set up your digitizer:
1. If you are using an application development environment(ADE) or
third-party tool, install it nowif yo uh avenot already done so. The
supportedADEs include LabVIEW, LabWindows/CVI, and other C or
C++ environments.
Note You must install all of the included software before installing your hardware.
2. InstallNI-SCOPE. The included NI-SCOPE CD contains the software
you need to configure,test, an d program operation of the NI 562x.
