The GHFLI and SHFLI microwave lock-in amplifiers from Zurich Instruments extend the advantages of lock-in detection—such as noise rejection, phase sensitivity, and frequency tracking—to the gigahertz range. With measurement frequencies of up to 1.8 and 8.5 GHz, respectively, the instruments are suitable for measuring periodic signals in such applications as RF MEMS and NEMS characterization and control, spin qubits, ultrafast laser spectroscopy, spintronics, and electronic-devices failure analysis. Each of two independent lock-in channels can measure multiple signals in parallel and generate multitone waveforms, and a full microwave measurement suite includes an oscilloscope, spectrum analyzer, and parametric sweeper. Eight demodulators allow users to simultaneously measure up to eight harmonics—or eight arbitrary frequencies with the multifrequency option—and provide signal amplitude and phase outputs for each harmonic or frequency. The demodulator filters reveal the best trade-off between noise rejection and measurement speed, with a time constant tunable between 14 ns and 21 s.

The 7000 series from Berkeley Nucleonics is an all-in-one solution that offers a set of low-noise functions for basic phase measurement. According to the company, having both absolute and additive residual measurement capabilities makes the 7000 series the most flexible tool of its kind on the market. It comprises a two-channel cross-correlation system with two internal, tunable reference sources; it also allows measurements with externally sourced references. The 7000 series can measure down to −190 dBc/Hz and evaluate signal sources ranging from VHF to microwave frequencies. Three platform options are available, each covering a different frequency range: the 7070, from 1 MHz to 7 GHz; the 7300, from 1 MHz to 26 GHz; and the 7340, from 1 MHz to 40 GHz. Applications include high-speed production testing of phase noise; voltage-controlled oscillator testing and characterization; additive phase-noise characterization of amplifiers, transmitters, and mixers; ultralow phase-noise oscillator analysis; and time stability analysis of clocks.

Sutter Instrument’s family of integrated patch amplifiers (IPAs) enable efficient, low-noise, whole-cell recordings in electrophysiology applications. Available in either single- or dual-headstage versions, the amplifiers combine state-of-the-art technology with fully integrated digital-to-analog and analog-to-digital conversion and a high-speed USB interface. Data are managed using the bundled SutterPatch data acquisition and analysis software, which is built on the foundation of Igor Pro from WaveMetrics. The IPA system, in combination with the SutterPatch software, automatically captures and stores all amplifier settings, stimulus information, and external experiment parameters and associates them in time with the raw data traces. The scope window supports multiple view modes in both a 2D and a novel 3D display, which is useful during assay development. Sutter Instrument, One Digital Dr, Novato, CA 94949,

Aerotech has added new products and features to its Automation1 software-based precision machine and motion-control platform. The number of compatible hardware products has increased, so more systems can use Automation1 as their core motion controller. Servomotor drives now include the XC6e higher-powered pulse-width-modulation model and the XL5e and XL2e linear amplifier servo drives. With the new MachineApps tool, users can quickly build and deploy graphical user interfaces for machines and motion systems. The Automation1 iSMC (software-based machine controller) connects with broader factory and laboratory automation systems via the new Python application programming interface and LabVIEW virtual instruments. The Studio development software now offers tools to streamline the development process. Those include configuration checklists, homing and motor-phasing helper modules, and parameter comparison and copying tools. Upgraded servo tuning and data visualization tools come standard.

Rohde & Schwarz has upgraded its R&S RTP (real-time processing) high-performance oscilloscope. According to the company, the compact, flexible instrument is not only easier to use but also delivers the fastest possible acquisition for real-time signal-integrity analysis. The R&S application-specific integrated circuit enables an acquisition rate of 750 000 waveforms/s, which helps users more easily spot, isolate, and analyze design defects in circuit boards. The new models are offered in bandwidths of 4–16 GHz with a sample rate of up to 40 Gs/s. To reliably capture and analyze long events or sequences, the standard acquisition memory has been increased to 100 megapoints per channel; 3 gigapoints per channel is optional. The R&S RTP-K39 user-defined math option expands the possibilities for analysis of captured data. Users can call a Python script for complex calculations and display the results as a math signal on the oscilloscope. Rohde & Schwarz GmbH & Co KG, Mühldorfstraße 15, 81671 Munich, Germany,

The latest addition to Siglent’s Performance Series, the SDG7000A, is the company’s most powerful family of arbitrary waveform generators to date. Excellent output performance and flexibility make the SDG7000A suitable for use in the development of embedded electronics. The generators are offered in three bandwidths: 350 MHz, 500 MHz, and 1 GHz. Their two independent channels can be combined to simulate interference on the main signal or easily generate complex modulated signals. In addition to standard waveforms such as sine, square, triangle, and pulse, the SDG7000A generators can output Gaussian noise with device-specific or limited bandwidth. All are equipped with 512-megapoint memory for creating custom signals. User-defined signals can be generated with Siglent EasyWave software or directly on the device display; arbitrary curves can also be imported from text or comma-separated-values files.

Golden Software has released the latest version of its Grapher software for visualizing and analyzing diverse data sets. Grapher is used by scientists and engineers in academia, climate research, environmental services and consulting, and exploration. Enhancements to the software include improvements in axes and plots: Users can now add as many breaks as needed to a single axis, format the breaks with various symbols, and position them as desired on the axis. Inverse relationships, such as the Arrhenius plot relationship between temperature and activation energy, can now be plotted by linking the axes to each other. To easily compare distributions between data sets, such as changing patterns on periodically collected data, users can plot multiple histogram sets together by means of stacked or adjacent bar charts. To improve the appearance of exported 3D graphs, plot transparency is now supported in all 3D plot types, including surface and bubble.

CAS DataLoggers has made available the sq16 and sq16-plus from Grant Instruments. They build on the capabilities of the previous Squirrel data loggers and feature updated SquirrelView software, a built-in Bluetooth communications interface, and the new SquirrelView mobile app. The data loggers provide universal analog input channels to measure current, voltage, resistance, temperature, humidity, pressure, flow, wind speed, and concentration of species. Digital channels can be set to automatically trigger or stop logging if an event occurs. Both the sq16 and the sq16-plus offer eight differential channels that can accept up to 16 sensors. The sampling rate is up to 8 Hz in the sq16 and 100 Hz for two channels in the sq16-plus. The sq16 provides support for two-wire resistance measurements; the sq16-plus offers three- and four-wire resistance. Multiple loggers may be linked, which saves space and enables measurement and monitoring of up to 128 channels of data at once. CAS DataLoggers, 8437 Mayfield Rd, Unit 104, Chesterland, OH 44026,
