Taking Measurements
with the NI PXI-562x
The NI PXI-5620 is a 64 Ms/s, 14-bit frequency-domain digitizer
module optimized for the best possible noise and distortion performance
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.
The NI PXI-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
wider front-end bandwidth, the NI PXI-5621 is functionally identical to the
NI PXI-5620.
Refer to the NI PXI-5620 Specifications and the NI PXI-5621
Specifications documents for NI PXI-562x performance specifications.
This chapter provides information on installing, connecting signals to,
and acquiring data from the NI 562x modules.
The NI 562x family 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 now if you have not already done so. The
supported ADEs include LabVIEW, LabWindows/CVI, and other C or
C++ environments.
Note You must install all of the included software before installing your hardware.
2. Install NI-SCOPE. The included NI-SCOPE CD contains the software
you need to configure, test, and program operation of the NI 562x.
