The 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.

The HP 8981B vector modulation analyzer (and HP 8780A/8782B vector signal generators) can be used to adjust and troubleshoot I/Q modulators, demodulators, and I/Q modulated signals used in digital mobile radio, microwave radio, and the transmission of digital video. The analyzers can be connected to the I/Q outputs of a demodulator in a receiver, or to IF test points. Once connected, the 8981B displays constellations, EYE diagrams, and vector diagrams of digital modulation formats such as QPSK, 16QAM, 64QAM, and 256QAM. The analyzer also makes statistical measures of system quality such as closure, lock angle error, and quadrature error. Through these “constellation analysis” techniques, transmission quality can be measured and monitored to detect degradations in the transmission link before link bit error rates reach unacceptable levels.
This unit has not been tested, and is sold “as is”.

The Hewlett Packard 3581A Wave Analyzer resolves and measures the amplitude and frequency of spectral components. This instrument offers accurate amplitude and good frequency resolution in the form of a portable, easy-to-use measuring tool. Since not all signals originate from a stable frequency source, the HP 3581A incorporates an AFT circuit which locks to a drifting signal for stable, accurate measurements.

The Hewlett-Packard Model 5345A Electronic Counter is a reciprocal counter capable of direct measurements to 500 MHz. The counter’s ability to accept plug-in accessories extends its inherent capabilities and provides for a variety of additional measurements. The instrument measures frequency, period, period average, single-shot time interval, time interval average, and ratio. It also provides a totalize function, whereby two signals can be simultaneously totalized with the displayed result being the sum or difference in the total number of counts. Using the 5245 series of plug-ins (with 10590A Adapter) extends the frequency rage to 18 GHz and adds other features, such as DVM capability.
This unit does not include any modules, and has a damaged pot on the front control panel, but is otherwise functional.
