Transition Time Converter, 250ps
15432B
The new design of these transition time converters ensures very low signal reflection far beyond the 3 dB point, unlike conventional converters. Reducing the signal transition-times also increases the overall pulse-performance for overshoot/reflection sensitive applications. The converters are fitted with SMA connectors, one male, one female. These converters have been designed to convert the fixed transition-times of the Keysight 8133A 3 GHz timing generator (<100 ps transitions) to slower, fixed transition-times (150 ps, 250 ps, 500 ps, 1 ns, 2 ns) hence reducing the signal bandwidth. All transition-times are from 10% to 90% of amplitude.

Time Machine
Retro-Fi
Retro-Fi is a time machine, constructed to take you back to a time when the most common way of hearing the latest hit music was AM radio. The music of that time included many styles and sounds, but the way the music sounded was always the same, owing to the limitations of the medium.

Timing Signal Generator
OSA 5548C TSG
Our OSA 5548C Timing Signal Generator (TSG) is a scalable synchronization solution ranging anywhere from 20 unprotected outputs up to a thousand protected outputs by adding up to four expansion shelves to the core unit. Its ultra-compact footprint makes it ideal for telecom operators to provide scalable network synchronization in over-crowded exchanges. The OSA 5548C TSG’s distributed intelligence message passing system eliminates single points of failure and guarantees reliable uptime. Core unit and expansion shelves share the same modules, minimizing overall administrative complexity and enabling reduced homologation activity.

Standard Directional Gyroscopes
4000B-series
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

Standard Gain Horns
Standard gain horns can be used to experimentally determine the gain of other antennas by using the substitution method. The standard gain horn and the antenna under test are alternately connected to a well matched detector system in order to compare their relative power levels. The power level difference is then added to the appropriate level of the calibration curve to determine the absolute gain of the antenna under test.View more Standard Gain Horn Antennas

Primary Standards
Primary standards (often also referred to as mechanical dead-weight testers, pressure balances or primary pressure standards) are the most accurate reference instruments for pressure. Their functional principle is based on the physical principle of pressure = force/area. Mass pieces placed on the top of a piston-cylinder system are the source of a precisely defined force. By producing a certain (counter) pressure inside the primary standard an equilibrium is achieved: the mass pieces, including the free-running piston of the piston-cylinder system, are floating, which will lead to a very accurate pressure at the test port which measured through piston gauge technology.
