An inexpensive frequency variable square waveform generator (WFG) was developed to use with existing sinusoidal waveform driven ion funnels. The developed WFG was constructed using readily available low voltage DC power supplies and discrete components placed in printed circuit boards. As applied to ion funnels, this WFG represents considerable cost savings over commercially available products without sacrificing performance. Operation of the constructed pulse generator has been demonstrated for a 1 nF ion funnel at an operating frequency of 1 MHz while switching 48 V.
我们开发了一种价格低廉的频率可变方波发生器（WFG），以便与现有的正弦波形驱动离子漏斗配合使用。所开发的WFG是使用现成的低压直流电源和放置在印刷电路板上的分立元件构建而成的。应用于离子漏斗时，这种WFG在不牺牲性能的情况下，相比市售产品可节省大量成本。已证明所构建的脉冲发生器在1 MHz的工作频率下、切换48 V电压时，可用于1 nF的离子漏斗。
