GENERAL INFORMATION
9
Internal digital IQ modulation is supported by a built-in dual-channel arbitrary waveform
generator (ARB). This ARB is compatible with waveforms designed or packaged using the
®
software application. Differential baseband I and Q outputs from the ARB are
available as an option. External digital IQ modulation is supported via an LVDS data
interface.
An external synthesizer provides the local oscillator input signal: the 3010 Series RF
Synthesizer is recommended. This and the Digital RF Signal Generator together occupy only
three slots in a 3U PXI chassis (four slots for 3021C/3026C).
Applications
The 3020 Series is ideal for generating complex modulated waveforms for WLAN, WMAN,
cellular communications, digital radio communications test and measurement applications,
satellite and terrestrial TV broadcasting and military communications. When a 3020 Series
module is used with other Aeroflex PXI RF modules, complete RF test systems can be
implemented easily. High RF accuracy, stability and repeatability ensure consistent
measurement results, helping to improve manufacturing yield.
PXI Express compatibility
Those 3020 Series modules which are hybrid slot-compatible PXI-1 peripheral modules (see
table) comply fully with the PXI-1 specification, except that the (upper) J2HM connector is
replaced by a smaller eHM (XJ4) connector. They are compatible with both standard and PXI
Express chassis.
Wide frequency coverage
The frequency range of the 3020 Series makes it ideal for multi-purpose applications in MF,
HF, VHF and UHF radio communications, especially important when testing multi-mode
cellular terminals.
Low noise and frequency-agile
When used with a 3010 Series synthesizer, the 3020 Series provides the low noise and high
switching speed necessary for high-productivity RFIC testing or the stimulus to frequency-
hopping radios.
