Operation outside of this specification is possible, but performance is not characterized and is not guaranteed.
Two input tones at -25dBm per tone.
This spurious response is caused by a higher-order mixing product (2x2). Specified RF frequency is applied and IF output
power is observed at the desired IF frequency (70MHz).
SMT贴片机是表面贴装技术（Surface Mount Technology）中的重要设备，它的性能状态对电子制造的质量和效率有着决定性的影响。因此，对SMT贴片机的主要指标性能进行定期检测非常重要。以下是一些主要的检测项目： 定位精度：定位精度是SMT贴片机的核心性能指标，它直接影响到贴片的准确性。通常，我们通过重复测量贴片机在X、Y轴上的移动误差来检测其定位精度。 贴片速度：贴片速度...[详细]
