Rohde & schwarz delivers highly accurate calibration technology to us air force
its precision measurement equipment laboratories (PMEL’s) and Air Force primary standards laboratory (AFPSL). According to these requirements Rohde & Schwarz has developed the R&S FSMR3000AF measuring receiver to calibrate signal generators and attenuators with one single instrument. Most important features provided are tuned RF level measurements, level measurements, analogue modulation and spectrum analysis. This is the second order in recent months that AFMETCAL has placed with Rohde & Schwarz. AFMETCAL is responsible for the calibration
A
of equipment used worldwide. They write all procedures for calibrating equipment at over 60 PMEL’s. AFMETCAL required nearly all the parameters of a signal generator to be calibrated with the R&S FSMR3000AF microwave measurement receiver including analogue modulation for AM, FM and PM. Also, on the purchase were alignment systems and/or equipment or accessories required for periodic recertification and adjustment of the MMR. This procurement seeks to replace and improve upon the microwave measuring receiver which was implemented in 2005 and the first one to reside on a spectrum analyser platform. Designed with a goal to reduce the
complexity associated with the calibration of signal generators and attenuators, the R&S FSMR3000AF measuring receiver test platform incorporates innovative features and functionality that reduces a calibration’s lab test process complexity. The 26.5GHz and 50GHz instruments provide all needed measurement capabilities integrated in a single box instrument taking up minimum space. The high dynamic of the R&S FSMR3000AF

FMETCAL, the Air Force Metrology and Calibration Authority, has been seeking to purchase microwave measurement receivers (MMR) for
provides for a level measurement range of – 148dBm to +30dBm. In addition, the instrument’s high linearity of 0.01dB + 0.005dB per 10dB step in conjunction with absolute power calibration with a power sensor provides highly accurate signal level measurements. A built-in analog modulation analysis capability
that encompasses AM, FM, and PM modulation measurements is incorporated by the R&S FSMR3000AF. AM modulation depths from zero to 100 per cent and FM frequency deviations as wide as 16MHz can be measured. For the modulation analysis an internal signal analysis bandwidth of up to 80MHz is provided by the instrument with a 16-bit A/D converter with 200Msamples/s, which can be used for modulation measurements on digital signals as well, if the vector signal analysis option is installed. The R&S FSMR3000AF provides for high
performance spectrum analysis measurements. For base frequencies above 8GHz, a preselection filter option is utilised to address image frequency suppression and unwanted mixing products. Accordingly, it offers complete analysis capability of harmonics, spurious emissions or phase noise up to 50GHz. Marker functions and measurement functions for all interesting spectrum measurements are provided, e.g. to measure noise power, ACLR, harmonic distortion, occupied bandwidth, spectrum emission masks. The resolution bandwidth can be set between 1Hz and 10MHz and channel filters are provided in addition. The Air Force Metrology and Calibration
(AFMETCAL) Program will use the R&S FSMR3000AF from Rohde & Schwarz to ensure Air Force (AF) systems and equipment are accurate, uniform, reliable, and traceable to national metrology institute or other sources as approved by AFMETCAL (Metrology).

dditel’s 260Ex is an Intrinsically safe Handheld Multichannel Reference Recorder with eight different channel configurations.
Armed with Additel’s most versatile and capable handheld, technicians are now able to measure and collect data for pressure, temperature (RTD probes available), barometric pressure and electrical measurement all in one highly portable device. The powerful logging capability and high-level of intrinsic safety make the ADT260Ex the perfect companion for use in the pipeline industry by supporting hydrostatic pressure testing, air leak testing, inlet and outlet pressure testing at pump stations, safety valve and ex-proof membrane testing, wellhead pressure testing, pipeline filter testing, differential pressure transmitter/flow computing testing, as well as routine calibration of pressure devices. With three pressure module inputs, one switchable at the bottom and two digital inputs on the side, and a variety of electrical inputs, users can configure the setup accordingly and easily meet the needs of pressure calibration and testing in virtually any environment.
The ADT60Ex Handheld Pressure
Calibrator provides pressure measurement accuracies as good as0.02%FS. This new pressure calibrator is loaded with extra features such as voltage and current measurement capabilities, Bluetooth and USB communications, datalogging capabilities and a rechargeable lithium battery. Additel provides professionals with the
best possible experience with the colour touchscreen display. With an easy to navigate menu structure and fast touchscreen response, the ADT260Ex calibrator is simple yet powerful to use. The display is easy to read indoors and outside and is built rugged to handle the demands of a busy technician in the field or the laboratory.
