(接2月下)3.3.1.13道间干扰各通道之间的道间干扰,对于任一通道,折合到输入端其峰峰值都应不超过输入信号的5%。检测方法:参照JJG 1042-2008《动态(可移动)心电图机检定规程》6.3.14条的相关内容。3.3.1.14共模抑制比大于80dB。检测方法:如果产品频响上限不小于50Hz,且不具有50Hz陷波器或50Hz陷波器可关闭,则执行JJG1042-2008标准6.3.15条试验方法;非上述产品则试验方法由企业自定,测试信号频率取20Hz或设备频响范围的中值。
(Continued in February) 3.3.1.13 Inter-channel interference Inter-channel interference between channels shall not exceed 5% of the input signal for any channel, as converted to the input. Detection: Refer to JJG 1042-2008 “dynamic (removable) electrocardiograph test procedures” 6.3.14 of the relevant content. 3.3.1.14 common-mode rejection ratio greater than 80dB. Test method: If the product frequency response is not less than 50Hz upper limit, and does not have a 50Hz notch filter or 50Hz notch filter can be closed, the implementation of JJG1042-2008 standard 6.3.15 test methods; , Test signal frequency take 20Hz or equipment median frequency range.
