Rohde And Schwarz Adds Signal Generator Options

Rohde and Schwarz is now offering two new options for its RandS SMA100A analogue high-end signal generator. By adding the RandS SMA K27 option, users can quickly configure different pulse trains for tests in radar-specific development, production and maintenance. An external pulse generator is no longer needed. The RandS SMA K28 option can analyse signal power versus frequency, power and time by using the RandS SMA100A signal generator together with a power sensor from the RandS NRP-Z family.

Pulse trains consist of pulses that have different durations. Their pulse width and pulse pause can be user configured. Such signals are frequently used in radar systems. Interfering with such pulses is far more difficult than with pulses sent at regular intervals. In addition, these pulses enable radar receivers to detect incorrect measurements more easily and to prevent blind spots on the radar image. The RandS SMA-K27 option is based on the pulse modulator integrated into the RandS SMA100A as standard and the optional high-performance pulse generator (RandS SMA-K23), utilising their dynamic range and speed.

As a result, the user can quickly generate pulse trains with very short rise and fall times - using only one instrument. Previously, such scenarios could only be created by using an additional external pulse generator, which meant a more complex test setup. The RandS SMA K28 option enables the user to perform a power analysis of signals directly by using the RandS SMA100A and a power sensor from the RandS NRP-Z family. Using the analysis function versus time, the user can measure different parameters such as pulse rise and fall times as well as pulse width and pulse dynamic range.

In addition, DUT analyses versus power and frequency are possible, such as when measuring the compression point or the frequency response. Markers make it possible to determine the power at a specific point. The RandS SMA-K27 (pulse trains) and RandS SMA-K28 (power analysis) options are available now from Rohde and Schwarz.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
