With the program AD9854C.exe one can set and tune the frequency in CW-mode. For use as a receiver LO also IF can be given and the both possible receiving frequencies are printed on the screen. The level in Q-outputs can be varied by giving the wanted attenuation in dB. This function is done by controlling a 12b digital multiplier in the device. In this case the level decreases somewhat with increasing frequency as it does in DDS devices. Alternatively the inverse sinc correction can be chosen, in which case the output is flat and high. -With the program AD9854C.exe one can set and tune the frequency in CW-mode.

MSC-51系列单片机内有128B或256B的RAM数据存储器，对一般应用场合，内部 RAM可以满 足系统对数据存储器的要求，但对需要大容量数据缓冲器的应用系统（如数据采集系统），仅片内的RAM存储器往往不够用，这种情况下，就需要在单片机外部扩展数据存储器。 MSC-51与外部数据存储器的一般连接方法：外部数据存储器的高8位地址由P2口提供，低8位地址线接地址锁存器的输出端。外部RAM的读、写控制信号分别接MCS-51的 、 。外部RAM的片选信号可由P2口未用的地址线的剩余口线以线选方式或译码方式提供。 随机存贮芯片（RAM）HM62256的存贮量为32KB，地址线有(A0～A14)，是单片机应用系统中最常见的数据存储器 -err
