Product
DQPSK Demodulator
-
Differential Quaternary Phase-Shift Keying (DQPSK) is the four-level version of DPSK. DQPSK transmits two bits for every symbol (bit combinations being 00, 01, 11 and 10) and has an additional advantage over conventional binary DPSK. DQPSK has a narrower optical spectrum, which tolerates more dispersion (both chromatic and polarization-mode), allows for stronger optical filtering, and enables closer channel spacing. As a result, DQPSK is the only modulation format which allows processing of 40Gb/s data-rate in a 50-GHz channel spacing system.

500 MHz Active Differential Probe
AP033
Differential Probe
Fully Integrated: With the ProBus™ interface, the AP033 becomes an integral part of the oscilloscope. The probe sensitivity and offset can be controlled from the oscilloscope front panel, the probe front panel, or by using remote control commands (GPIB or RS-232). Sensitivity, offset, input capacitance, and common mode voltage range are displayed on the oscilloscope screen. When used with a LeCroy digital oscilloscope, no external power supply is required.

Three Axis Interferometer
10736A
Differential Interferometer
The Keysight 10736A Three Axis Interferometer is used in multiple axis applications where linear and angular control of the stage is required. It combines in a single package the functionality of an optical bench with multiple beam benders, beam splitters, and three interferometers. The interferometers split an incoming laser beam into three beams to measure linear distance, pitch and yaw, or linear distance, roll and yaw. Three linear measurements provide the basis for calculating two angular measurements. The inherent beam parallelism ensures that there is essentially no cosine error between the three measurements and also ensures angle accuracy for pitch and yaw measurements. Other characteristics include:

One Axis Differential Interferometer
10719A
Differential Interferometer
The Keysight 10719A One Axis Differential Interferometer makes either a differential linear or angular measurement for use in single and multiple axis applications. The linear measurement gauges the displacement between two objects, such as a stage and an optical column or inspection tool. The 10719A also measures either pitch or roll. An angle is measured when both reference and measurement beams measure to the same mirror. The 10721A provides high immunity to unwanted interferometer displacement, such as thermal expansion. It is a modular, compact design with monolithic optics for maximized mechanical stability. Use of a small 3 mm beam helps decrease Abb offset error.

Plane Mirror Interferometer
10706A
Differential Interferometer
The Keysight 10706A Plane Mirror Interferometer is a dual pass interferometer used for multiple axis applications such as X-Y stages where the measurement mirror may move perpendicular to the measurement axis. The unique contribution of the 10706A is its tolerance of angular misalignment of the plane mirror reflector. The 10706A can accept a range of measurement mirror angular alignment changes.
