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 -10dBm以上 +1dB
-10dBm以下 +2dB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
VSWR is better than 1.5:1 for output levels below -7 dBm.单位切换 By keyboard entry. Units may be uV, mV, V EMF or PD; dB relative to 1 uV, 1 mV EMF or PD; dBm. Conversion between dB and voltage units may be achieved by pressing the appropriate units key (dB, or V, mV, uV). 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 返回上一页
