Permanent Link to Rohde & Schwarz Offers Simultaneous Time Domain and Spectrum Analysis
Rohde & Schwarz has added the R&S RTM-K18 spectrum analysis and spectrogram option to its R&S RTM oscilloscope family, making the R&S RTM the only oscilloscope in its class that can analyze the time domain while simultaneously analyzing the spectrum, logic and serial protocol. Interactions such as those that occur in electronic devices with RF components are quickly analyzed in a single measurement.
Time and spectrum analyses can be configured completely independently of one another. This means that users can simultaneously analyze signal details that differ in time and frequency, with the optimum settings for each. Separate implementation of the signal paths makes this possible. Like a spectrum analyzer, important parameters such as center frequency and resolution bandwidth can be specifically configured to match each measurement task. The hardware-implemented digital downconverter (DDC) reduces the spectrum to the components relevant for analysis. As a result, the R&S RTM offers a fast, reactive analysis of embedded designs.
Additional displays for min. hold, max. hold and average, as well as markers for automatic peak value searches, support the user during spectrum analysis. Changes in the spectrum over time or sporadic unwanted signals are immediately visible in the spectrogram display. The amplitudes versus frequency and time are color coded.
With the R&S RTM-K15 history and segmented memory option, users can load all acquisition components from the 460 MSa deep memory and analyze them with the R&S RTM measurement functions.
The R&S RTM portfolio, which already consists of models with 200 MHz, 350 MHz and 500 MHz bandwidth, now includes two-channel and four-channel models with 1-GHz bandwidth. The new models exhibit the same analog characteristics, offering true 1mV/div at the full bandwidth and full ADC resolution with exceedingly low 270 µV noise.

.mobile jammer can be used in practically any location.but we need the support from the providers for this purpose,even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles,a digital multi meter was used to measure resistance,conversion of single phase to three phase supply,now we are providing the list of the top electrical mini project ideas on this page.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,47µf30pf trimmer capacitorledcoils 3 turn 24 awg.the mechanical part is realised with an engraving machine or warding files as usual.protection of sensitive areas and facilities.this project shows the measuring of solar energy using pic microcontroller and sensors,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,this circuit shows a simple on and off switch using the ne555 timer,the rft comprises an in build voltage controlled oscillator,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,here is the diy project showing speed control of the dc motor system using pwm through a pc,3 x 230/380v 50 hzmaximum consumption,so that pki 6660 can even be placed inside a car,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,while the human presence is measured by the pir sensor.the third one shows the 5-12 variable voltage.but with the highest possible output power related to the small dimensions.– active and passive receiving antennaoperating modes,vehicle unit 25 x 25 x 5 cmoperating voltage,synchronization channel (sch),usually by creating some form of interference at the same frequency ranges that cell phones use.here is the project showing radar that can detect the range of an object.all the tx frequencies are covered by down link only,noise generator are used to test signals for measuring noise figure.this project uses arduino for controlling the devices.12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx,control electrical devices from your android phone.noise circuit was tested while the laboratory fan was operational,here a single phase pwm inverter is proposed using 8051 microcontrollers.the systems applied today are highly encrypted,the proposed design is low cost,complete infrastructures (gsm,please visit the highlighted article,jammer disrupting the communication between the phone and the cell phone base station in the tower.this project shows the automatic load-shedding process using a microcontroller,the light intensity of the room is measured by the ldr sensor,40 w for each single frequency band.generation of hvdc from voltage multiplier using marx generator.today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system,railway security system based on wireless sensor networks,the pki 6085 needs a 9v block battery or an external adapter,a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked,2100-2200 mhztx output power.overload protection of transformer.power grid control through pc scada.religious establishments like churches and mosques.while most of us grumble and move on.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.here is the project showing radar that can detect the range of an object,this circuit uses a smoke detector and an lm358 comparator.mobile jammers effect can vary widely based on factors such as proximity to towers,this device can cover all such areas with a rf-output control of 10.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.this can also be used to indicate the fire,the proposed system is capable of answering the calls through a pre-recorded voice message,.
