Properties of the 565 include 500 ps resolution; independent channel gating, amplitude, and polarity; the control of both the delay and width of each channel; and the ability to sum the timing of the various channels to any other channel and to select timing references for each channel. Gate, burst, delayed enable, and divide by N modes are included. The 565 s optical options allow users to combine both optical and electrical outputs in pairs. For example, on a four channel device, two or four of the outputs can be optical.

Standard features include electronic attenuation and a sweeping CW source. The new instrument uses an advanced software defined radio architecture with a 500 MHz digital signal processor that enables fast data acquisition and processing. For example, the 2810 can perform a 200 MHz span sweep in approximately 15 s using a narrow resolution bandwidth of 100 Hz.It also provides greater than 30 MHz of 3 dB measurement bandwidth with 20 MHz of flatness within 1 dB; wide bandwidth signals can be captured in one acquisition. The 2810 can decompose digitally modulated signals into their in phase and quadrature phase components.

The frequencies of the four outputs can be independently set and can be offset by a controllable phase. All output frequencies (32 bits), amplitudes (10 bits), and phases (14 bits) are independently controlled by an RS 232 serial port at 19.2 kbaud. The 409A can store up to 33 000 profile points consisting of phase, frequency, dwell time, and amplitude settings. It is equipped with a ±1.5 ppm onboard clock and can accept an external clock source up to 500 MHz. When used with the external clock, all 409A units can be synchronized to a system wide frequency standard. Novatech Instruments Inc, P.O.

The module incorporates circuits for discrimination of avalanche photodiode output pulses at very low current levels and active quenching circuitry with response times under 10 ns. In combination, these features provide the least time jitter and afterpulsing said to be available in commercial indium gallium arsenide/indium phosphide photon counting technology. The SU 02 SPC single photon detection tool offers user control over a broad range of such parameters as gate duration, repetition rate, detection probability, and dead time. Applications for the new module include ultrasensitive Raman spectroscopy and quantum key distribution.

The WaveRunner 104Xi provides a 1 GHz bandwidth, an upgrade from the 400 MHz and 600 MHz models; the 204Xi offers a bandwidth of 2 GHz. Sampling rates for both are 5 gigasample/s on four channels, interleaved to 10 GS/s. The model 104Xs in creases the WaveSurfer oscilloscope line to 1 GHz of bandwidth with a sample rate of 2.5 GS/s on four channels, to 5 GS/s interleaved. All WaveRunner Xi models will now be supplied with 10 megapoints/channel of memory, interleaved to 20 Mpts/ch. The increased memory will enhance analysis tools and application programs, such as histograms, long memory FFTs, user defined functions, jitter and timing analyses, and mixed signal options.

The new equipment makes it possible to synchronize the laser pulses to other pulsed instruments, such as synchrotrons, accelerators, and pulsed magnets, for use in pump probe spectroscopy and optical sampling. The PLL option also enables synchronization to highly stable RF oscillators, such as those referenced to atomic clocks, to generate frequency combs. It includes a phase delay input port that provides users with a means to scan laser pulses with respect to a reference signal. The variable delay ranges from 400 ps to +400 ps and thus is equivalent to an optical delay line of 12 cm.

The two models achieve their rated 125 W power out put by efficiently combining the outputs from four 50 W (nominal) microwave tubes that are factory matched in gain and phase. The model 125T18G26 covers the 18 26.5 GHz frequency range; the 125T26G40 covers 26.5 40 GHz. Both models exhibit an output flatness over the respective frequency ranges of ±8 dB maximum and require 1.0 mW input for rated output. The amplifiers include VSWR protection and gain control and provide a front panel display that shows forward and reflected out put and extensive system status information. The new TWTs are designed for applications for which wide instantaneous bandwidth, high gain, and high power output are required.

The scanner, which can scan as many as eight images simultaneously at speeds up to 48 Hz, can be positioned in z to accommodate larger samples up to 21 mm thick. The 5400 uses a low coherent laser with a small spot size for low interference imaging and has open access to the sample plates and simple alignment of optics; it uses PicoView software, a new design with streamlined graphic user interfaces. To increase its appeal as a teaching instrument, the company is including undergraduate curriculum materials with each system.

Additional clock inputs and outputs can now be added to enable phase locking up to 20 MHz to a common signal, a feature that is helpful in applications in which several pieces of equipment work in concert under one time frequency, thus eliminating timing phase shift. The generator can multiplex signal outputs together to form complex waveforms. Options such as optical output, input, and communication pack ages are important to trigger, delay, gate, and synchronize multiple devices for use in high RF interference and EMI environments. Other features include pulse incrementing that allows the width and delay of each channel to be incremented at the end of pulse bursts. Quantum Composers Inc, P.O.

By controlling the heat at the end of a probe tip, users can image a surface to study its topography as the surface undergoes physical change, including a glass transition, a recrystallization, or a melt. The nano TA accessory provides users with local thermal analysis measurements in which the probe is parked on top of a feature and then heated. The deflection of the probe will then follow the behavior of the sample; for example, it may show initial expansion, then undergoes a glass transition, causing the probe to appear to sink into the surface, indicating the free volume change at that temperature.

Amotor that varies from 0 to 10 000 rpm is adjusted by a precise motor control unit to give a particular flow rate, deter mined by monitoring a highly repeatable differential pressure sensor that has been calibrated to an accuracy of 1% of reading to an individual wind tunnel in a system. Each WT4401 is supplied with two restrictive plates for achieving optimum low flow rates. The established differential pressure measurements versus flow rates are listed from 25 to 9000 feet/min. An optional deluxe instrumentation package is available for monitoring temperature, barometric pressure, humidity, and differential pressure.
