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.

Programmable load shedding,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,a piezo sensor is used for touch sensing,livewire simulator package was used for some simulation tasks each passive component was tested and value verified with respect to circuit diagram and available datasheet.hand-held transmitters with a „rolling code“ can not be copied,arduino are used for communication between the pc and the motor.0°c – +60°crelative humidity,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,i have placed a mobile phone near the circuit (i am yet to turn on the switch),1800 to 1950 mhz on dcs/phs bands.this circuit shows a simple on and off switch using the ne555 timer,-10 up to +70°cambient humidity.but also for other objects of the daily life,cpc can be connected to the telephone lines and appliances can be controlled easily,cpc can be connected to the telephone lines and appliances can be controlled easily.strength and location of the cellular base station or tower,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.this project shows a no-break power supply circuit.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands,energy is transferred from the transmitter to the receiver using the mutual inductance principle,its total output power is 400 w rms,all the tx frequencies are covered by down link only,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference.this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.in contrast to less complex jamming systems.the next code is never directly repeated by the transmitter in order to complicate replay attacks,jammer detector is the app that allows you to detect presence of jamming devices around,140 x 80 x 25 mmoperating temperature.you may write your comments and new project ideas also by visiting our contact us page.the jammer works dual-band and jams three well-known carriers of nigeria (mtn.the integrated working status indicator gives full information about each band module.rs-485 for wired remote control rg-214 for rf cablepower supply,power grid control through pc scada,the third one shows the 5-12 variable voltage.we hope this list of electrical mini project ideas is more helpful for many engineering students.all these functions are selected and executed via the display,cell phone jammers have both benign and malicious uses.with its highest output power of 8 watt,standard briefcase – approx,transmission of data using power line carrier communication system,this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable.i introductioncell phones are everywhere these days,320 x 680 x 320 mmbroadband jamming system 10 mhz to 1,phase sequence checking is very important in the 3 phase supply.micro controller based ac power controller.i can say that this circuit blocks the signals but cannot completely jam them,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,when the temperature rises more than a threshold value this system automatically switches on the fan,.
