特点 (1)噪声源开态和关态的电压驻波比小,且数值与相位基本相同,故测试精度较高; (2)可脉冲调制,配接自动噪声测试仪作快速测量。 性能 频率范围: 8.2～12.4GHz 超噪比(ENR): 3～8dB 平坦度: ±0.5dB 电压驻波比(VSWR)(两态):≤1.08
Characteristics (1) The noise source has a small VSWR at on-state and off-state, and its value and phase are basically the same. Therefore, the test accuracy is high. (2) Pulse-modulated and connected with automatic noise tester for rapid measurement. Performance Frequency range: 8.2 ~ 12.4GHz ENR: 3 ~ 8dB Flatness: ± 0.5dB VSWR (two-state): ≤1.08
