8970A Noise Figure Meter Operating and Service Manual. Part Number: 08970-90014 (May85). This manual contains info required to install,operate,test,adjust and service and is provided for info only. It covers instruments with serial # prefixes of 2116A thru 2438A. The 8970A is no longer sold by Keysight.

The HP 8970A front panel buttons control the number entry, cali-bration, and measurement functions. STORE, RECALL, and SEQ buttons allow up to 9 front panel settings to be stored and sequenced automatically or manually to save set-up time. Smoothing IN-CREASE and OECREASE buttons are used to average up to 512

Applications and Operations of the 8970A Noise Figure Meter (PN8970A-1) Part Number: 08970-99000 (Nov81). The 8970A is a discontinued product; this product note is provided for …

8970A 8970A Noise Figure Meter With the 8970A Automatic Noise Figure Meter, accurate and re- peatable noise figure measurements are now easy. RF and microwave (with an external local oscillator) measurements from 10 MHz to at least 26.5 GHz are equally simple; any IF between 10 and 1500 MHz may be used.

hp 8970b（hp8970a hp8970b）的动态围允许进行至少40db(在某些情况下，还会更高)的增益测量，或达-20db的损耗测量。 HP 8970B可存储4个超噪比ENR(Excess Noise Radio)噪声源校准表。

2023年12月8日 · The HP8970A noise figure meter takes the mystery out of noise figure measurements, making them easy, accurate and repeatable. The HP8970A can be used with the 346 or 347 family noise sources. Low instrument uncertainty and automatic second-stage correction make it possible to make accurate noise figure …

There are multiple versions of the 8970A controller boards, earlier boards use a 3.6 V NiCd rechargeable battery, but these tend to leak, and are now no longer available. The unit I am dealing with has a more recent control boards, using a BR2325 Lithium cell (3.0 V).

2014年9月19日 · 8970A可存储4个超噪比ENR（Express Noise Radio）噪声源校准表。 还可在每个测量频率上适当内插ENR值。 微处理器和控制器功能. Agilent 8970A使得噪声系数测量不再神秘化。 为达到真正精确、方便和灵活的噪声系数测量，使用一个微处理器来进行计算和必要修正。 此仪器还可控制外接本机振荡器（如8370系列合成器，8340或8360系列合成扫频源或8350扫频振荡器）和8971C噪声系数测试装置。 这就使得微波频段的放大器、混频器、晶体管的精确， …

2015年5月24日 · With the 8970A back working, what would be the first thing to do with it – well, let’s measure some gains and noise figures. Unfortunately, the 8970A alone won’t be sufficient, because it uses a small, external noise source unit, commonly refered to as a 346A, B (or C model, if you need noise up to 26.5 GHz).
