HP 8970B, 8971C & 346A
"HP 8970B
The Agilent 8970B noise figure meter takes the mystery out of noise figure measurements, making them easy, accurate and repeatable. The 8970B 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 readings, even for low-gain devices. The instrument has special measurement modes for mixer measurement and is capable of controlling external local oscillators and the 8971C noise figure test set.
HP 8971C
The Agilent 8971C noise figure test set allows the 8970B to make noise figure measurements over an extended frequency range. Careful design and high-performance components, including a stable YIG filter, allow broadband single-sideband measurements from 10 MHz to 26.5 GHz with a single calibration and sweep. A low-noise preamplifier built into the noise figure test set lowers the second-stage noise figure, thereby reducing a major source of measurement uncertainty. Measurement modes in the 8970B allow for double down-conversion using the 8971C as the second downconverter.
HP 346A
The Agilent 346A 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
