Together with measurement application software supplied they provide first class vector signal analysis of RF signals. Their functionality and performance are ideally matched to the needs of RF test systems for manufacturing or design verification. The 2 slot wide 3030A frequency down converts and digitizes RF signals in the range 330 MHz to 3 GHz providing an instantaneous analysis bandwidth of up to 36 MHz. The single slot wide 3010 / 3011 RF Synthesizer module provides the low phase noise, frequency agile local oscillator input to the RF digitizer. The 3030A offers high linearity, low noise and excellent level accuracy performance making it especially suited for the analysis of WLAN, WMAN and 2G / 3G cellular radio signals. The 3030A outputs amplitude and phase corrected digital IF or IQ data samples with an absolute amplitude accuracy of better than 0.45 dB (typically 0.3 dB). Correction ensures amplitude flatness is maintained better than 0.25 dB across 33 MHz bandwidth with phase compensation better than 0.03 radians pk-pk. The Aeroflex PXI Studio application software provides a basic framework for vector signal analysis. As standard PXI Studio supports hardware configuration, control and display of IQ data in various domains ideal for general purpose testing and alignment of radio communications transmitters and components. As they become available, optional measurement library plugins to the basic software can then easily be added. Plugin libraries integrate existing .dll measurement library options within the PXI Studio framework thereby providing an intuitive API and a highly flexible graphical user interface. Plugin support of specific communications system personalities will extend to include GSM/EDGE, UMTS/HSUPA UL, cdma2000/1xEV-DO reverse link, WLAN and WMAN (WiMAX) signal analysis in additon to general purpose Spectrum Analysis. For the very latest specifications visit www.aeroflex.com Advantages of PXI The 3030A RF digitizer offers significant economies compared to general purpose rack and stack instruments without compromising performance. In part this is achieved by exploiting the benefits of the PXI specification, an industry standard open architecture for modular instrumentation. Using PXI enables faster measurement speed, smaller size and greater flexibility for easier system integration and future system evolution. Applications The RF Digitizer is an essential component within any development or manufacturing RF test system designed around the needs of advanced digital communications standards as used in WLAN, WMAN and cellular communications. The 3030A is equally beneficial for applications in satellite and terrestrial broadcasting and military communications. Whether the application is for test, measurement or system emulation, the 3030A delivers the functionality and performance required. When used in conjunction with other Aeroflex PXI RF modules, complete RF test systems can be designed. The 3030A RF digitizer is complementary to the 3020 series digital RF signal generators which can provide wideband linear modulated RF signal generation up to 6 GHz with integrated dual channel arbitrary waveform generator. Performance Highlights Wide Frequency Range: The 3030A provides continuous frequency coverage from 330 MHz to 3 GHz with 1 Hz resolution. This satisfies the requirements for all mobile phone operating bands as well as WLAN, WLAN licenced and unlicenced bands below 3 GHz. Level Range: Full dynamic range is provided for signal input powers up to +10 dBm peak. The maximum safe input range is extended to + 22 dBm (with 8 dB input attenuation selected). With a noise spectral density specification of –145 dBm/Hz, the 3030A is able to discern very low level signals, especially useful when measuring transmitter spurious outputs. RF Input level control is provided using reliable, fast electronic switched attenuation selectable in small 4 dB steps to help maximize the useable dynamic range. Level Accuracy: The 3030A is ideal for making accurate RF power measurements in high volume manufacturing. A typical 0.3 dB total measurement uncertainty together with <0.05 dB repeatability error ensures that a high yield can be maintained. High Dynamic Range: The 3030A is purpose designed for difficult transmitter measurements such as burst power and spectral emissions on WLAN/WMAN, 2G and 3G cellular terminals. With a spectral density of –145 dBm/Hz, 3030A is able to measure steep power ramps as generated by 2G, 3G and WLAN/WMAN radio transmission equipment. For GSM type signals, power ramps of 80dB can be measured. The digitizer typically provides 75 dB of spurious free dynamic range and 75 dB intermodulation free dynamic range. This together with excellent phase noise performance makes it possible to measure an ACLR of typically 68 dB on 3G terminals. Frequency conversion is performed using a highly linear single stage down converter which offers a TOI of +30 dBm and low conversion loss. Wide Bandwidth: The 3030A provides a bandwidth of 36 MHz with phase and amplitude correction across 33 MHz. This can help improve measurement speed by making it possible to use a single capture to acquire multiple carriers or wide band width modulated signals such as used in emerging WLAN standards. Low Phase Noise: The 3030A module is designed to be used either with a PXI 3010 or 3011 RF synthesizer module. This provides a low noise agile local oscillator signal from which the 3030A phase noise is defined. Phase noise at 20 kHz offset from carrier is typically -115 dBc/Hz at 2 GHz while he noise floor from 10 MHz offset is typically –138 dBc/Hz. Frequency settling can be achieved in typically 250 µs, (3010 opt 01 fitted) making the 3030A ideal for high productivity RFIC testing. IF Input: The 3030A will accept a direct IF input signal at 77.76 MHz with a maximum input level of +10 dBm. Flexible ADC: Full rate digital IF or decimated IQ data can be streamed via a LVDS data interface on the front panel. This is especially useful for realtime system emulation applications. Data can also be captured to internal memory then read over the PCI bus. Internal memory provides storage for up to 128 M x 16 bit samples of IF data sampled at 103.68 Msamples per second, equivalent to 1.2 seconds. The sample rate is user defined and independent of the sampling clock over the range 6.328 ks/s to 85 Ms/s. Lowering the sample rate improves data transfer rates and allows much longer events to be captured. Small Size: The 3030A is unparalleled in terms of size. The module occupies just 2 slots in a 3U PXI rack. An additional slot is required to accommodate the 3010 RF synthesizer making a total of just 3 slot widths required for a complete RF digitizer. Acquisition, Data Transfer and Measurement Speed: Data acquisition, data transfer and measurement processing can be performed serially or overlapped. New data acquisition can be initiated in parallel to processing a previous capture sample thus leading to faster measurement time. Data transfer time to the CPU is performed at a rate of up to 20 MSamples/s (IF data) or 10 Million IQ pairs per second while measurement processing time varies according to CPU speed and the application. Triggering and Synchronization: The 3030A module can frequency lock to a 10 MHz reference signal supplied by the 3010. The 3030A supports external trigger sources. Triggers can be applied either from the PXI backplane or directly through the front panel LVDS and TTL interfaces. The 3030A is able to initiate data capture based on an internal IF trigger derived from sample data. IF triggering can be set as absolute, with a user defined threshold level, or relative in which case a power change results in trigger activation. Both trigger modes have settable time constants for noise filtering making it possible to avoid false triggering on transients. All trigger modes are supported by user definable pre- and post trigger delays. 3030 data acquisition is also able to be gated. The sample length is then defined by the duration of the externally applied gate. List Mode: This feature enables the 3030A to be preloaded with up to 128 combinations of different frequency and level settings. All 3030A internal hardware settings are pre-calculated making re-selection of a new frequency and level possible in typically 250 µs, (3010 opt 01 fitted) while still maintaining level accuracy. This feature is ideally suited for fast mobile phone transmitter alignment applications and is complimented by similar features in the 3020 series RF Signal Generator in support of the corresponding fast mobile phone receiver alignment. Software FFT Spectrum Analyzer Measurement Suite Highlights The 3030A is supplied with a variety of software including; measurement applications with optional system personality plugins, measurement suites (function libraries), instrument drivers and soft front panels. 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 measurement 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). 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 module 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 suited for fast characterization and alignment of radio transmitters. Occupied Bandwidth is calculated from the FFT spectrum by a function that returns the bandwidth in which a user defined percentage 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 discrete 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.
