此次测试的是放大电路,rpx 的基础频率是1.544mhz,扫频模式(50khz-150khz,4vpp,Square wave),放大电路运行正常,除了放大电路的一个电容发热,如果换成银云母电容后将运行更好。波形图中绿色是放大电路输出波形,黄色是芯片TC4426的输出波形。放大电路的电源使用的是12v和24v两种用来测试的。
the test is running rpx combining amp。fundamental frequency is 1.544mhz,sweeping mode(50khz-150khz,4vpp,Square wave),all runs perfectly,except a cap of the amp is very hot and not stable。in the wave picture RED is amp output wave,yellow is TC4426 output wave。input current is 0.2A when the rpx turn on an then down to 0.1a。the power source of amp is 12v/24v。
