輸出電平 | -127 to +13 dbm (0.2 uv to 2 v emf). when am is se-lected 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 | +1 db (-10 dbm 以上) |
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 n型頭 |
zui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 |
