hp8970b描述
Agilent 8970B噪声系数测试仪解开了噪声系数测量的神秘面纱，使测量变得更加容易、且可重复进行。而且它可与346或347系列噪声源一起使用。凭借较低的仪器不确定性和自动的第二阶段修正功能，即使对于低增益设备，8970B也能够生成的噪声系数读数。该仪器为混频器测量提供了专用的测量模式，而且可以控制外置本地示波器和8971C噪声系数测试装置。

346B Noise Source option 002 and special option H72 Discontinuance Notice: The
Agilent 346B noise source Option 346B-002, and special Option 346-H72, noise
sources which use an APC-7.0 mm connector, will be discontinued on October 31,
2003. This will also be that last day to order these options. The support life
will be 5 years (until 31st October, 2008). There is no Agilent recommended
replacement.

The Agilent 346B noise source is the ideal companion to Agilent's noise figure
solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the
necessity for several sources at different frequency bands. The low SWR of the
noise source reduces a major source of measurement uncertainty; reflections of
test signals. The 346B's high ENR, low SWR, and variety of connectors make it
a general-purpose noise source. Add special option H01 for high ENR (21 dB
typical) to measure high noise figure devices, or option H42 for measuring
Direct Broadcast Satellite (DBS) low noise block converters.
