The HP 5341A Frequency Counter performs exceptionally fast measurements of frequency up to 4.5GHz. Using a unique HP-designed microwave switchable filter, its automatic heterodyne measurement technique insures high tolerance of FM on the measured signal. In the normal mode of operation, the Agilent HP 5341A will automatically measure and display the lowest CW signal within its sensitivity; in the manual mode, the operator can choose to search within any of ten frequency bands which cover the counter’s full range. Type N & BNC connectors; ±1% accuracy; 50-ohms.

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.
