輸出電平 -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.
單位 單位可以是uV, mV, V EMF or PD; dB相當(dāng)于1uV, 1 mV EMF or PD; dBm.
顯示 4 位 LCD 顯示精度 0 .1 dB 輸出電平精度 -10dBm以上 +1dB
-10dBm以下 +2dB輸出電平平坦度 Better than +0.5 dB from 10 kHz to 1 GHz for output levels above -7 dBm.
輸出阻抗 50歐
VSWR is better than 1.5:1 for output levels below -7 dBm.單位切換 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). 最大單邊帶噪聲 -120 dBc/Hz Harmonics (noise) -35 dBc Non-harmonics (noise) -40 dBc 外接頻率參考 10 MHz 返回上一頁(yè)
