Interfaces
The use of a Windows XPTM operating system allows for a wide
range of interfaces. Included in the unit are: USB, LAN,
Centronics parallel printer port, RS-232, IEEE 488 (GPIB) and VGA
output. A wide range of printers can be installed and updated by
the installation of drivers from the CD ROM supplied with the
printer.
Signal Demodulation
In addition to the standard demodulation feature of AM and FM
the 3280A Series also includes as standard a 30 MHz bandwidth
digitizer in its product range as well as basic digital modulation
analysis S/W. Its digitizer provides the optimized H/W conditions
for various mobile and wireless communication measurements
such as WiMAX/WiBRO, etc.
• 14 bit ADC with 85.6 MHz sampling frequency
• Dynamic range over 80 dB
• 32 M samples data with 128 MB memory
• Standard FFT, spectrogram, digital modulation analysis
• Save I/Q data file
• Digital modulation analysis like PSK (8, 16, 64), QAM (4, 8,
16, 32, 64, 128, 256), BPSK, QPSK.
Semi-Automated Measurements
The evaluation of many of the common measurements can be
simplified by the use of built-in measurement functions. These
include: channel power, adjacent channel power, occupied
bandwidth, spectrum emission mask, TOI measurement,
harmonic distortion, X dB down and phase noise measurement.
Optional Tracking Generator
A tracking generator option is available for all three frequency
models. The tracking generator has a specified frequency range
of 9 kHz to 3 GHz and a level range from 0 dBm down to -70
dBm with 0.1 dB resolution. The tracking generator can be used
to make high dynamic range measurements on components
and devices, particularly filters. A normalize function is available
to allow the markers to display relative flatness/frequency
response.
