High Accuracy AC Reference Source
515
-
Clarke-Hess Communications Research
The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.

Universal Differential pH Water Quality Sensors
SD7500CD
-
Continuous online pH monitoring in wastewater and coating industrial applications leads to contamination and eventually requires sensors to be replaced. A differential pH sensor utilizes a measurement technique designed to extend the working lifetime of sensors in challenging applications. Replacing the sensor reference (salt bridge) and buffered electrolyte solution can prevent sensor replacements, saving time and money. Our SD7500 Series features a combination sensor output; these differential pH sensors can be used with any conventional pH/ORP transmitter.

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.

-
The 3440A measures the true rms of low level RF and microwave signals to over 1GHz. High rms accuracy, traceable to NIST, is assured regardless of waveshape. Common calibration errors are eliminated through temperature compensation of the probe detector diodes; double shielding protects the interchangeable probes from rough handling and pickup. Relative gain or loss measurements are simplified by a 0 dB reference adjustment. DC output proportional to the ac input is provided for analog recorders and to allow operation as an ac-dc converter.

The S930902B spectrum analysis adds high-performance microwave spectrum analysis to the PNA family up to 26.5 GHz. With fast stepped-FFT sweeps resulting from optimized data processing, the SA application provides quick spurious searches over broad frequency ranges. Simultaneous spectrum measurements can be done using up to five test and reference receivers. This multi-channel SA can be used with the internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. The SA application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy.

Thorlabs' LLD1530 Frequency-Locked Laser is a narrow linewidth, DFB-laser-diode-based, turnkey system with a vacuum emission wavelength of 1532.8323 nm and a high SMSR of at least 35 dB. The laser frequency is actively stabilized to a National Institute of Standards and Technology (NIST)-traceable molecular transition of acetylene and has an absolute accuracy at start-up that is better than ±25 MHz. The emission frequency immediately after start-up is then maintained with a ±25 MHz stability, providing an overall frequency accuracy of ±50 MHz. The LLD1530 is an accurate frequency reference designed to provide low-noise laser emission with excellent frequency stability, accuracy, and precision immediately at start-up. This source is ideal for use in demanding FTIR instrumentation, instrument calibration, gas sensing, and coherent telecommunications applications.
