HP 4936A TRANSMISSION IMPAIRMENT MEASURING SET ANALOG/DIGITAL SIGNAL TESTER

The HP 4936A Transmission Impairment Measuring Set is a piece of test equipment manufactured by Hewlett-Packard (now known as Keysight Technologies) in the 1980s. It is used to measure and analyze the impairments present in telecommunication transmission systems.

The HP 4936A was specifically designed for testing analog and digital communication circuits and transmission facilities. It is capable of measuring various parameters that affect the quality and performance of the transmission, including attenuation, noise, distortion, and impedance. The instrument provides a comprehensive set of tools and functions for accurately characterizing and troubleshooting communication links.

Some of the key features of the HP 4936A Transmission Impairment Measuring Set include:

1. Impairment Analysis: The instrument can measure and analyze impairments such as amplitude distortion, frequency response, signal-to-noise ratio, crosstalk, and phase distortion.

2. Frequency Range: It operates over a wide frequency range, typically up to 1.5 MHz, allowing it to handle a variety of transmission systems.

3. Test Patterns: The HP 4936A can generate and analyze various test patterns, including standard digital test patterns like PRBS (Pseudo Random Binary Sequence) and modified test patterns.

4. Error Performance: It measures error performance parameters such as bit error rate (BER), frame error rate (FER), and errored seconds.

5. Impedance Measurement: The instrument provides impedance measurements to determine the characteristic impedance of a transmission line.

6. Data Storage: It has the capability to store test results, allowing for later analysis and comparison.

7. User Interface: The HP 4936A features a user-friendly interface with a built-in display and keypad for easy operation and configuration.
