I/Q调制信号源 AMIQ 性能指标
AMIQ是一个可以产生I/Q信号的基带信号源。它通过WinIQSIM来编程和设置,也可以通过矢量信号源SMIQ来控制。自动幅度调整和微调使得AMIQ的IQ两路的输出具有很好的对称性,误差矢量因此可以降低到最小,这一点以前的双通道任意波形发生器是很难做到的。每个通道可以存储4M(R&S AMIQ03)或者16M(R&S AMIQ04)的采样点,因此可以产生足够长度的高符号速率的信号序列。时钟频率可以高达100M sample/s,幅度分辨率为14比特(数字IQ输出可以达到16比特)。这些特性使得AMIQ成为数字调制信号源的理想选择。
特点
The I/Q Modulation Generator R&S AMIQ and the Simulation Software R&S WinIQSIM open up new dimensions for the generation of I/Q signals. The R&S AMIQ is a dual-channel modulation generator that has consequently been designed for use as an I/Q source. It is programmed and set with the Software R&S WinIQSIM. The R&S AMIQ outputs I/Q baseband signals or even can generate an IF signal (up to 25 MHz). High Flexibility
The software R&S WinIQSIM that is delivered with the R&S AMIQ can simulate either single carrier signals, multi carrier signals or CDMA/W-CDMA signals with an unchallenged flexibility. All signal parameters can be programmed freely. A flexible Data Editor allows the individual configuration of TDMA signals. Preprogrammed standard settings for the most common communication standards are supplied with WinIQSIM. Furthermore with the external Software R&S WinIQOFDM and the option R&S AMIQK15 signals according to the standards HIPERLAN/2 or IEEE 802.11a can be generated. 100 MHz sample rate
The AMIQ offers an internal clock rate of 100 MHz (105 MHz in overrange). 16 MSamples memory depth
With the large memory of AMIQ e.g. up to 100 W-CDMA frames can be generated. Integrated hard disk and floppy disk drive
Internal hard disk drive (8 GByte) 14-bit resolution (16 bit with optional digital output AMIQ-B3)The AMIQ‘s 14 bit DA conversion guarantees low quantization noise and ensures best signal quality regarding spectral purity which is ideal e.g. for multicarrier applications. IF generation up to 25 MHzNo additional RF-Generator is needed. Baseband and IF-Signals can be generated with one box. That means lower costs and only one single box for signals up to 25 MHz. No modulation errors occur due to the fact that the IF-signal is calculated from the baseband signal. That makes the AMIQ an ideal source for demodulator tests! Multi carrier simulation
The AMIQ offers an internal clock rate of 100 MHz (105 MHz in overrange). Optional Bit Error Rate (BER) measurement (AMIQ-B1)
The BERT option (AMIQ-B1) for AMIQ allows BER measurements on a DUT with PRBS data. For this purpose the AMIQ sends a PRBS sequence to the DUT and simultaneously synchronizes on the demodulated bits provided by the DUT. Optional differential I/Q outputs (AMIQ-B2)
Differential I/Q outputs are available as an option for the AMIQ (AMIQ-B2) Optional digital output (AMIQ-B3)
Beside the analog I/Q output the AMIQ provides also the digital signal output when equipped with the option AMIQ-B3 Application Import of user waveforms
The application software IQWizard (Download) allows to import waveforms created with SW tools such as MATLAB, MATHCAD, COSSAP, etc |
应用举例基带衰落模拟器ABFS的应用(图中AMIQ用来产生I/Q调制信号, 输出在AMIQ的前面板I和Q输出端口, 也可以使用其他信号发生器来产生I/Q信号, 但需要注意最大输入电压不能超过±5V) |
