调频调幅信号发生器Marconi 2022D

　　厂家：英国马可尼

　　频率范围: 10 kHz to 1 GHz(7位液晶显示精度10 Hz up to 100 MHz, 100 Hz above 100 MHz) 输出幅度: -127 dBm to +13 dBm 调制：调频、调幅、调相;外接调制;三种内部调制频率Aux modulation input 体积小巧，方便携带152 x367 mm , 7.5 kg 100组记忆设定强大的第二功能键用于快速故障定位和校准Reverse power protection up to 50 W Choice of output cal. unitsOutput level can be offsetParameters can be incremented 输出电平-127 to +13 dBm (0.2 uV to 2 V EMF). When AM is selected the max. output power reduces linearly with AM depth to +7 dBm at maximum AM depth.

　　单位单位可以是uV, mV, V EMF or PD; dB相当于1uV, 1 mV EMF or PD; dBm.

　　显示4位LCD 显示精度0 .1 dB 输出电平精度+1 dB(-10 dBm以上)+2 dB(-10 dBm以下)

　　输出电平平坦度Better than +0.5 dB from 10 kHz to 1 GHz for output levels above -7 dBm.

　　输出阻抗50欧N型头VSWR is better than 1.5:1 for output levels below -7 dBm.

　　最大单边带噪声-120 dBc/Hz Harmonics (noise) -35 dBc Non-harmonics (noise) -40 dBc 外接频率参考10 MHz
