FG-72(7MHz DDS Function Generator) 函数波形产生器
0.3Hz-7MHz数字合成函数波形产生器(DDS Function Generator).
0.56英吋高.6位数.绿色.高亮度.大型数字LED显示频率.
单位按键直接输入Hz.KHz.MHz..最方便输入欲产生的频率.
正弦波.方波.三角波.共3种波形选择.任何频率都能输出7MHz最高频率.
任何波形输出都有TTL位准的同步信号输出.更加方便使用.
共二组-20dB的衰减开关..最大波形20Vp-p(1M Ohm负载).10Vp-p(50 Ohm负载).
全部按钮都使用塑料硬键(非橡胶软键)最耐用.触感最佳.
直流抵补+-10V(1M Ohm负载). +-5V(50 Ohm负载)独立开关选择.
内含RS232 (或USB) 输入装置.无须加价购买.非常方便学术论文撰写.
透过RS232 (或USB) 控制接口.可以由计算机远程控制输出频率.波形.衰减开关等.
