hp8970b描述
Agilent 8970B噪聲系數(shù)測(cè)試儀解開了噪聲系數(shù)測(cè)量的神秘面紗，使測(cè)量變得更加容易、且可重復(fù)進(jìn)行。而且它可與346或347系列噪聲源一起使用。憑借較低的儀器不確定性和自動(dòng)的第二階段修正功能，即使對(duì)于低增益設(shè)備，8970B也能夠生成的噪聲系數(shù)讀數(shù)。該儀器為混頻器測(cè)量提供了專用的測(cè)量模式，而且可以控制外置本地示波器和8971C噪聲系數(shù)測(cè)試裝置。

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.
特性
Low SWR for reducing noise figure (NF) measurment uncertainty
Individually calibrated ENR values at specific frequencies to enhance accuracy
Calibration supplied on floppy disk for easy loading into NFA-series noise
figure analyzers
