The integration of an auto-sync laser function gives users two devices in one: a portable stroboscope and a digital handheld tachometer with laser measurement. The tachometer function can be used up to a distance of about 3 m. The laser beam is aimed at a reflection mark. The reflected beam triggers the receiver which is […]
Tabletop enclosures provide -110 dB attenuation for EMI/RFI work
The SFI High Attenuation Frameless Enclosures guarantee more than -100 dB RF/EMI attenuation in a quick-setup tabletop enclosure. The frameless design allows a smaller footprint, easier storage, and guarantees high attenuation than the RF/EMI Shielded Tabletop Enclosure. These lightweight fabric enclosures are also quick and easy to break down, and store. SFI Frameless Enclosures are […]
Working with scope-based spectrum analyzers
The spectrum analyzer is a member of the oscilloscope family. An electrical signal is fed, by means of a BNC cable or probe, into an input port on the front panel, and its graphic image appears on the LCD screen. But rather than the oscilloscope’s familiar time domain graph, in which amplitude in volts is […]
PC-based scopes boast 5 GSa/sec real-time sampling and 4 GSa-deep memory
The 4-channel PicoScope 6000E Series 500-MHz oscilloscopes provide 8 to 12 bits of vertical resolution and up to 5 GSa/sec sampling rate with 4 GSa memory, allowing these scopes to display single-shot pulses with 200-psec time resolution. The three four-channel models added to the existing eight-channel 6000 series are the PicoScope 6403E with 300-MHz bandwidth […]
PC-based scopes provide four-channel measurements
PicoScope 6000E Series compact 4+16 channel MSOs deliver cost-effective test and debugging solution for engineers, developers and scientists. Pico Technology has further developed its PicoScope 6000E Series oscilloscopes with the launch of three new four-channel models, each of which can be configured with 16 optional digital channels. With bandwidths of 300 or 500 MHz, 8-bit […]
Current generator meets advanced safety requirements for automotive and pyrotechnical apps
Quantum Composers, Inc. added new features to the 9730 Series Programmable Current Generator which provides engineers with the ability to generate complex current waveforms and generate 6 A of high-precision current pulses. The 9730 is designed specifically to meet the advanced safety test requirements of USCAR-28 and AK-LV-16 for testing pyrotechnical systems, airbag systems, and […]
Basics of voltage doubler circuits
Voltage can be doubled (and therefore multiplied by any power of two using cascading devices) through purely electronic means without resorting to a transformer. Voltage-current ratios apply, so doubling is not a question of getting free electrical energy that did not previously exist. Doubling the voltage and thus reducing the current available at the output […]
Basics of troubleshooting power supplies
When a piece of equipment turns up completely dead, one of the first things to look at is the power supply. If using an oscilloscope for this sort of troubleshooting, it should be a hand-held, battery-powered instrument isolated from ground, at least at the outset. The reason is there may be internal voltages that are […]
Test instruments carry new 1.35-mm E-band coaxial connector
The R&S NRP90T and R&S NRP90TN thermal power sensors support the novel, robust 1.35-mm precision coaxial connector. The connector covers frequencies up to 90 GHz and shall be included in the next releases of both IEEE and IEC relevant standards. Rohde & Schwarz has been a partner in the 1.35-mm E connector development project since […]
RF signal generators put out analog, vector signals over 9 kHz – 4 GHz/6 GHz with 0.001-Hz frequency-setting resolution
The Siglent SSG5000X RF Signal Generators generate analog and vector signals over a frequency range of 9 kHz to 4 GHz/6 GHz with a 0.001-Hz frequency setting resolution. They offer excellent performance in phase noise, spectral purity, bandwidth, EVM, and output power. The internal IQ modulation generator and waveform playback function on the -V models […]
