High-Speed Digitizers Acquire Analog and Digital Signals Simultaneously
Spectrum Instrumentation has announced a new digital input option (M4i.44xx-DigSMA) for its popular high-speed and high-resolution series of PCIe digitizers. The option consists of an additional module that sits beside the existing digitizer card to provide eight additional digital input lines. The digital input module shares a common clock and trigger with the base card so that both the digital and analog inputs are fully synchronous. This makes the combination ideal for a wide variety of mixed signal testing applications.
The Spectrum M4i.44xx series of PCIe digitizer cards consists of eight different models. Users can select from versions that have either two or four analog channels and sampling rates of 180 or 250 MS/s, with 16-bit resolution, or higher speeds of 400 or 500 MS/s, with 14-bit resolution. The digitizer cards of the "44" series are fully equipped with extensive analog signal conditioning (6 input ranges, selectable input impedance, offset, etc.) and advanced triggering capabilities.
The new M4i.44xx-DigSMA digital input option has a separate PCIe faceplate, occupying an additional PCIe slot, with 8x SMA type connector. Designed for versatility, each input has an impedance of 10 kOhms (to 3.3 V). This allows the inputs to handle 3.3 V LVTTL signals with input voltage levels between -0.5 V and +4.0 V. The digital input bandwidth is 125 MHz and software selection enables both synchronous and asynchronous acquisition modes.
For applications that require more channels, Spectrum enables multiple M4i.44xx series cards to connect with its Star-Hub system. Star-Hub permits a maximum of eight cards to all share a common clock and trigger.

E-Band Coaxial Connector for Thermal Power Sensor
By adding the R&S NRP90T and R&S NRP90TN models to its portfolio of thermal power sensors, Rohde & Schwarz releases the first test and measurement instruments to support the novel, robust 1.35 mm precision coaxial connector. The connector covers frequencies up to 90 GHz and will 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 its beginning in 2017.
An expert group with collective knowledge of microwave signal transmission initiated the joint project to develop and implement a new coaxial connector optimized for E-band frequencies. Emerging applications, in particular, for automotive radar from 76 to 81 GHz, plus the WiGig extension IEEE 802.11ay operating up to 71 GHz, highlighted the need for a novel, robust coaxial cable connector suitable for industrial applications at frequencies up to 90 GHz.
The result is the 1.35 mm E connector, with a precise metric fine thread, a reliable pin-gap, and an integrated groove for optional push-pull locking.
The E connector closes the gap between the well-established 1.85 mm connector (the V-band connector) and the 1.00 mm connector (the W-band connector). The V-band connector, introduced more than 30 years ago, is suitably robust for industrial applications, but is restricted to a maximum frequency of 70 GHz. The W-band connector, on the other hand, supports a maximum frequency of 110 GHz, but requires a fine-mechanical accuracy during assembly, and frequently loosens in use.

Material Level Detection Sensor
Thanks to the new level switch PL20, the CleverLevel series from Baumer now offers more possibilities for detecting point levels in materials. CleverLevel reliably detects every type of medium, whether liquid, pasty, viscous, or solid, and is therefore the solution for a variety of applications for which standard vibrating forks are used today. One of its major advantages is the fact that it does not have to be parameterized to a medium as before but flexibly adapts to the medium at hand. This way, even adhesions such as those that frequently occur with pasty materials can be reliably masked. With its optional 4–20 mA analog signal, the PL20 offers several additional advantages and true added value for increased efficiency of your production process.
Conventional measurement systems are unable to cope with the different media characteristics involved. The new level switch CleverLevel PL20 makes processes more flexible and eliminates additional efforts—because it no longer matters what is in the tank. The PL20 level switch offers true added value, especially when it comes to applications in the food production sector with changing recipes or batch production. The self-learning sensor automatically adjusts to the different media. This ensures maximum flexibility with minimum set-up times. In addition, thanks to its compact design and low installation depth, it has only a minor impact on the process and thus ensures maximum food safety.
Even adhesions such as those that occur with pasty materials and electrostatic charging do not affect the performance of the sensor. In such cases as well, the level switch adjusts the switching level without any type of parameterization, minimizing downtimes that may be caused by faulty switching. With an additional optional 4–20 mA analog output, the PL20 can help differentiate the media within the process or evaluate the cleaning process.
