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.

Model 1100-AR is a modular telemetry receiver, developed between 1969 and 1972 by Microdyne Corporation in Rockville (Maryland, USA). The receiver was aimed at the emerging lunar mission and satellite business of the late 1960s and early 1970s, but eventually became the workhorse for many tracking stations for the next three decades. Although it has since been succeeded by new designs, it is still widely used today (2019), mainly because of its robustness and reliability.
The receiver is fully modular and consists of a 4U 19″ rackmount enclosure that contains the basic circuitry, and has five bays for optional modules, which makes it highly customisable.
The two wide slots at the top are suitable for a CRT (spectrum) display or an RF field strength indicator, whilst the other slots are for the RF front-end (bottom right), the IF strip (centre) and a demodulator (bottom left). Depending on the application and the required frequency range, a selection of a range of modules and options could be installed in the 1100-AR mainframe.
Although the 1100-AR was primarily intended to be used as part of a satellite (or aerospace) base station, it was sometimes used as a reference receiver, an intercept receiver, and even as a surveillance receiver.

The MTS-1700 Series Universal Protective Relay Test System is a comprehensive relay test system designed for standard testing of polyphase and single-phase protection relays. It can perform steady-state and complex dynamic testing of relays, as well as fault playback (regeneration of digitized fault waveforms). It is meant to be computer controlled, and is particularly designed for simulation of faults in three phase systems. Advanced fault simulation capabilities, such as frequency, voltage, current and phase ramping, are standard. Full control of all functions via the RS-232C computer interface paves the way for automated testing of many types of protection relays.

The Modular Digital Pulse (MDP) module provides four 1 PPS TTL/CMOS compatible outputs through BNC connectors on its front panel. The module receives an internal 1 PPS signal and performs buffering and amplification of the output signals provided for use by external equipment.
All 1 PPS outputs are derived from a differential 1 PPS input that is applied to the MDP at backplane input P1. If this 1 PPS signal is removed, the fault detector will illuminate the FAULT LED within 5 seconds.

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.
