3030A Datasheet, PDF (3/8 Pages) Aeroflex Circuit Technology – Wideband RF Digitizer

Software
The 3030A is supplied with a variety of software including; measure-
ment applications with optional system personality plugins, measure-
ment suites (function libraries), instrument drivers and soft front
panels.
3030A Soft Front Panel
Driver Software All 3030 series modules are supplied with mutli
layered software APIs and GUIs starting with a low level vxi pnp mod-
ule driver to control the digitizer independently and then a higher
level driver providing a single combined interface to both the 3030
and 3010 series modules. Each driver is supplied with a .dll API and
is supported with a soft front panel GUI to aid manual operation and
debugging during applications development.
Application Software The 3030 series module is supplied with
application software 'PXI Studio' which provides a high level fully
intergrated API and GUI to all Aeroflex 3000 series signal generator,
digitizer, local oscillator and combiner modules and measurement
libraries. This vastly simplies the effort required to integrate PXI
without compromising flexibility.
The basic application supports module hardware configuration and
control through a single GUI and integrates measurement libraries
through a series of standard and optional plugins. The basic PXI
Studio application provides spectrum analyser functions as well as
allowing display of IQ data in various domains including ampltude vs
frequency, amplitude vs time, phase vs time, I vs Q (amplitude vs
phase). This application is ideal for general purpose measurements
in a wide variety of communication applications and particularly suit-
ed for fast characterization and alignment of radio transmitters.
FFT Spectrum Analyzer Measurement Suite Highlights
As standard 3030 series modules are supplied with an FFT Spectrum
measurement suite comprising a library of hardware independent
functions for frequency and time domain analysis of digitized IQ data.
To assist with programming, source code examples and user help are
provided for a wide variety of different applications development
environments including LabView, LabWidows CVI, VB and Visual C.
FFT analysis can be performed with a maximum span of 200 MHz..
The resolution bandwidth is continuously variable using 3 dB or
Noise Equivalent Bandwidth windows with a minimum resolution of
<1Hz.
Channel Power and Adjacent Channel Power Measurement
The user defines the channel configuration to be measured (i.e.
channel width; channel spacing; center frequency; etc). The meas-
urement then computes the central channel RMS power as an
absolute and the adjacent channel powers relative to this from the
FFT spectrum. Four adjacent channels are examined (two either
side of the central channel).
Occupied Bandwidth is calculated from the FFT spectrum by a
function that returns the bandwidth in which a user defined percent-
age of the total signal power is occupied.
The FFT spectrum can be configured as either RMS averaged or
peak hold in which case the function will output an averaged result or
retain peak values if repeatedly called. The number of averages is
user defined.
A marker power function is provided together with a marker peak find
and a next peak search function. These enable measurement of dis-
crete signals within the FFT spectrum.
Time domain analysis functions include computation of average
power of a range of IQ data samples plus power and frequency versus
time. The time window for analysis can be the entire IQ sample array
or any user defined subset.
Optional Measurement Suites. Signal analysis measurement
suites are also available for measurement of GSM/EDGE, WiMAX
WLAN, UMTS uplink and cdma2000 uplink transmissions. (See
separate datasheets for 3030 options 100 to 104). These provide
measurement of power, modulation quality and spectrum parameters
in accordance with the relevant standards for mobile terminal testing,
ideal for both production line and development laboratory use. Each
application library is supplied with example source code to help
familiarize the user.
Customer Support
Users can elect to purchase PXI modules with optional warranty
extensions. Standard Extended Warranty provides either a 36 month
or 60 month warranty period plus the benefits of guaranteed product
repair times in the event of failure. Standard Extended Warranty can
also be provided inclusive of scheduled calibration. On request
Aeroflex can provide customized Premium Warranty support
designed around your specific needs.
