PCI Three-Axis High Performance Laser Board with External Sampling
N1231B
Laser Board
The Keysight N1231B PCI Three-Axis Laser Board with External Sampling is a register based PCI bus board that implements three axes of laser interferometer measurement for position monitoring and closed-loop servo control. There are four external sample inputs along with four data hold inputs that allow easy synchronization with user systems. Several threshold compare registers, with both hardware outputs and interrupt capability, can be used for travel limit and in window or out of window detection functions. The dual mode hardware position outputs, controlled by the hold inputs, provide either a 32-bits/axis parallel interface or a 36-bit multiplexed interface to the 36-bit axis position data at rates up to 20MHz. The user can programmatically access the externally sampled position and velocity data, as well as software sampled position and velocity data, over the PCI bus at rates up to 100kHz (3 axes of position and velocity) or 200kHz (position or velocity only).

40Gb/s DQPSK Receiver
-
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

High Stability Plane Mirror Interferometer
10706B
-
The Keysight 10706B High Stability 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. This thermally stable optic, an exact functional replacement for the 10706A Plane Mirror Interferometer, reduces thermal measurement drift to 1/12 the value typically achieved by conventional plane mirror interferometers. The unique contribution of the 10706B is its tolerance of angular misalignment of the plane mirror reflector. The 10706A can accept a range of measurement mirror angular alignment changes.

Two Axis Differential Interferometer
10721A
-
The Keysight 10721A Two Axis Differential Interferometer, when used in multiple axis applications, simultaneously makes two differential measurements linear and angular (yaw) displacement. Both measurements reference external mirror mounted to an object such as a column or inspection tool. 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. The 10721A is similar to the 10719A Single Axis Differential Interferometer, except that it provides an additional measurement axis.
