安捷倫科技有限公司現(xiàn)已提供了基于PXI和LXI的15-bit任意波發(fā)生器（AWGs）用于創(chuàng)造同步發(fā)生的帶寬和高解決方案信號，用于雷達(dá)、人造衛(wèi)星、電信或軍事通信設(shè)備的電子測試。 利用15-bit垂直解析度，N6030A （PXI）和N8241A （LXI）產(chǎn)品在商業(yè)AWGs中產(chǎn)生了許多切實可行的多頻波。無失真動態(tài)范圍小于65 dBc，可用于每個通道，直流為500 MHz。噪音基底在整個通道的帶寬中小于150 dBc/Hz。 當(dāng)與安捷倫PSG矢量信號發(fā)生器多頻I/O轉(zhuǎn)爐相結(jié)合時，安捷倫的AWGs在頻率為44 GHz情況下，可實現(xiàn)1 GHz模擬帶寬，用于IF以及RF子系統(tǒng)測試的可靠信號模擬。 4插槽PXI N6030A和LXI N8241A有兩個通道，分辨率可達(dá)1.25 GS/s信號寬帶為500 MHz。標(biāo)準(zhǔn)波每通道長度為8 MS，還可以擴展至16MS。N8241A在每通道的取樣速率能達(dá)到625 MS/s。雙重輸出通道在測試路徑中不用應(yīng)用不平衡變壓器或混合適配器就能平衡地驅(qū)動兩端。 AWGs中的高級序列和擴展波記憶能夠提供長時間模擬用于擴展重放時間。多重編程界面，如來自MATLAB（r）的完整儀器控制，使其簡單整合到現(xiàn)存測試環(huán)境中，并簡化波形發(fā)展任務(wù)。 高清晰度圖片可登錄www.agilent.com/find/AWG_PXI_LXI_images 下載。 [FONT=times] original text [/FONT] [font=times] Agilent Technologies‘ 15-bit Arbitrary Waveform Generators Create Complex Wideband Waveforms for Optimum Test Signal Quality [/font] [font=times][Color=#708090]Agilent Technologies Inc. （NYSE: A） now offers PXI-based and LXI-based 15-bit arbitrary waveform generators （AWGs） that can create simultaneous wide-bandwidth and high-resolution signals for electronic testing of radar, satellite, telecom or military communication equipment. Using 15-bit vertical resolution, the N6030A （PXI） and N8241A （LXI） products generate the most realistic wideband waveforms available in commercial AWGs. Spurious-free dynamic range is less than -65 dBc for each channel, DC to 500 MHz. Noise floor is less than -150 dBc/Hz across the full channel bandwidth. When combined with the Agilent PSG vector signal generator wideband I/Q upconverter, Agilent‘s AWGs can achieve modulation bandwidths of 1 GHz at high frequency up to 44 GHz for authentic signal simulations for IF and RF subsystem testing as well. The 4-slot PXI N6030A and the LXI N8241A feature two channels, each offering 1.25 GS/s with up to 500 MHz of signal bandwidth, and a standard waveform length of 8 MS per channel that is expandable to 16 MS. The N8241A is also available with a 625 MS/s sampling rate at up to 250 MHz per channel. Dual output channels drive both single-ended and balanced designs without the need for balun or hybrid adapters in the test path. Advanced sequencing and extended waveform memory of the AWGs provide long scenario simulations for extended playback times. Multiple programming interfaces, such as the complete instrument control from MATLAB（r）, enable easy integration into existing test environments as well as simplify waveform-development tasks.
