High performance RF Signal Generator with built in complex modulation option.
The TGR2051 and TGR2053 are the next generation of RF signal generators from Aim-TTi, offering both exceptional performance and new improved functionality with touch screen operation.
The high-performance RF generators provide high frequency accuracy and stability, High signal purity with excellent Phase noise, Output power levels of -127dBm to +13dBm, and flexible analog and digital modulation capabilities, making it ideal for development, test and service work.
The sweep function enables signals of varying frequency and/or amplitude to test a full range of input conditions, quickly and efficiently. Step sweeps are created according to a formula over a specified number of points, in the range 2 - 1000 . Formula specifics include:
ElectroTest Expo 2020
ElectroTest Expo 2020 is the 10th anniversary of the unique PCB test and debug event aimed at design and test engineers and hosted by leading T&M equipments suppliers.
This year’s expo takes place on 29th April 2019 at Mini Visitor Centre, Cowley near Oxford - close to the centre of the country and accessible via excellent infrastructure links.
On show will be test, measurement and inspection instruments ranging from oscilloscopes, RF generators and other bench tools to integrated production test systems based on technologies including PXI, Flying Probe testers and JTAG/Boundary-scan. The free seminar program will also offer great value to those seeking the latest information in test and inspection. Choose from talks on JTAG/Boundary-scan, ATE Building, signal switching and high-integrity mass interconnection systems.

start and stop values and dwell time following SYNC at each point. Sweeps can be set to run in either direction, with linear or logarithmic spacing. Alternatively, list mode can be used to analyse the response at set frequencies and amplitude - dwelling on set values for specified amounts of time; useful for testing at known problematic frequencies within a setup. The list can be created within the instrument or downloaded via the remote interfaces. The sweep setups can either be run through as a single sweep or in a continuous loop and prompted by an internal, external or manual trigger. Complex sweep triggering is available to control complete sweeps and/or each point within a sweep.
The TGR-U01 option adds an extensive range of digital modulations: FSK, GFSK, MSK, GMSK, HMSK, 3FSK, 4FSK, PSK, ASK and OOK. Built in NRZ patterns include Square wave, 7, 9, 11 & 15-bit PRBS. Digital modulation capabilities also include advanced filtering: Gaussian, Raised Cosine, Root Raised Cosine and Half Sine as well as Grey Code and Binary Encoding. External digital modulation signals can be applied to the carrier waveform via the MOD in/out on the rear panel.

characters SPI and I²C MMS Electronics Ltd has available an exceptionally versatile line of DOG (Display-On-Glass) alphanumeric and graphic displays. The DOGS104-A and EA DOGS164-A are small high-contrast easy-to- read STN and FSTN displays. The double height character option transforms the EA DOGS104 4x10 into a 2x10 or 3x10 line x char display and the EA DOGS164 4x16 into 2x16 (6mm height char) display. The integrated SSD1803A controller has 3/4-wire SPI and 2-wire I²C interface. 3 fonts: Cyrillic, English-Japanese and European. Supply voltage is low power +3.3V. Typical only 440µA (with LED backlight off) makes it ideal for battery powered applications. Display and optional backlights are “mix & match”; there are 3 display variants transmissive, transflective and reflective with a combination of 3 different LED backlights: Amber, dual Yellow-Green/Red and a trio Green/Red/White. For quick evaluation without the need to write any code demo board EA 9780-4USB is available. MMS Electronics Ltd in Leeds is the authorised UK distributor for Electronic Assembly GmbH / Display Visions.
GTK launches Circular TFTs
GTK announces the recent addition of circular TFTs to their display range. These new displays are 2.1” and 2.5” in diameter and both have an excellent 480 x 480 resolution and 1:1 aspect ratio. They also incorporate IPS (in-plane switching) technology, which results in high contrast ratios and exceptional all-round viewing angles. Both displays use ZIF connectivity, with the 2.1” version having an MCU interface and the 2.5” utilising a MIPI interface.
Clive Dickinson, business manager for Displays at GTK, said, “These circular TFTs open up really creative design opportunities for OEMs. Up until now they have been confined to laying out a design using the available rectangular or, more recently, square footprints. Now they can design the display area to be the most intuitive for the user and end application.
“These displays can be used in a wide range of different applications and are ideal where a dial type view is required. I can see great benefits of using this layout for products required for elderly home care devices. We are already exploring opportunities with OEMs who are working on new product designs.”
Customisation options for both displays include custom sensors and cover lenses, and GTK’s technical experts can help OEMs with display selection, customisation and the connectivity to provide the required PCB interface.

New Omron 100A relay runs exceptionally cool Omron Electronics Components Europe is moving
into the high power relay market with the launch of a new 100A device featuring exceptionally low heat generation due to an ultra-low contact resistance. The new Omron G7EB is aimed at distribution power conditioning systems (PCS) as well as test equipment such as semiconductor testers.
According to Andries de Bruin, Senior European Product Marketing Manager, Omron, “The market for the distribution type of PCS is growing rapidly driven by the trend towards micro-generation from renewable sources. The challenge in these high current designs is controlling heat generation – a challenge which Omron directly addresses with this new design suitable for emergency cut off and similar high carry current applications.”
Attendees will receive free refreshments and will be entered into a draw for one of 15 places on a fascinating factory tour of the Mini assembly plant.
Omron Electronics Components Europe is moving into the high power relay market with the launch of a new 100A device featuring exceptionally low heat generation
Omron G7EB can switch up to 100A at 800Vac. A key feature is the ultra-low 5 milli-ohm contact resistance, an industry leading figure which greatly reduces heat generation within the component. This not only improves reliability by reducing the heat stress on the device and the surrounding circuit, but also minimizes energy wastage. As a result, the G7EB experiences a temperature rise to about +40 deg. C with a 100A carry current, as opposed to +80 deg. C for competing designs.
PCS designs commonly feature three or more of this type of relay, and the Omron device helps reduce system size with its compact dimensions of 40.5 x 50.5 x 37mm. The reduced requirement for heat sinks as a result of its cool operation yields further space savings for the system designer. Omron is offering the G7EB with both industry standard and Omron proprietary pin layouts.
