The U3800 is the industry's first metrology tool to offer phase measurement of two high-frequency signals in a single instrument, allowing operators to determine the phase difference. This new functionality enables quick and accurate detection of reception problems caused by inter-circuit interference or radio wave reflection, making the U3800 ideal for applications ranging from electromagnetic interference (EMI) challenges, to broadcasting and communications.
The U3800 series utilizes a new X math (pronounced cross math) function for comparative analysis of input from two channels. This function displays the waveforms of both signals on a single coordinate plain, enabling operators to see the phase difference between the signals at a glance. Furthermore the U3800 series can be used as spectrum analyzer.

Time difference (phase difference) is analyzed to connect antenna to each channel.
Simultaneous analysis of desired and undesired signals (interference, multipath, and noise) without missing unwanted signals even under fluctuant propagation conditions.
To connect a magnetic field probe to RF input and an electronic field probe to the other one, those intermitted and fluctuating radiation noise can be measured respectively. Furthermore, correlation between electric and magnetic field can be shown by real-time comparison with phase synchronization between channels.
Nowadays electric appliances contain RF modules, and electric devices like smart phones have some communication systems. A lot of radio interferences are expected, and communication signals carried in the device may interfere with each other. The interference signal in primary communication signal can be detected easily by 2ch time domain analysis.
Inverter for EV operates with high-voltage switching, which affects the operation of electric components in vehicles. 2 channel time domain analysis is useful for observing relationship between inverter clock and interfered signal by inverter noise.
Enable parallel measurement using vertical and horizontal antennas or dual measurement of different frequency bands.
Enable simultaneous multipoint noise measurement at a low cost.
Can measure power of noise signal at each antenna simultaneously, and furthermore analyze phase difference to the signal detected at reference antenna.
The level monitoring and interference signal monitoring are important to keep communication quality. RF/RF or RF/IF signals can be monitored simultaneously up to 43GHz by using 2 RF inputs.
Polarization multiplexed communication is used for effective utilization of radio frequency. Horizontal polarized waves and Vertical polarized waves are transmitted to the same frequency. XPD is one of evaluation items for communication, and “X math” function makes a direct reading of XPD value.
Pulsed signals are used for various equipment such as radar and so on. It is important for improving system quality to measure characteristics of its internal components or modules like amplifier. Cross Domain AnalyzerTM U3800 equipped with two RF inputs can easily measure Gain and Phase Distortion of the devices by using actual pulsed RF signal carried in the system.
Rader systems are used in various equipment like collision avoidance system. Time domain analysis of 40MHz capture bandwidth can help development and manufacturing of radar modules and systems.
For example, radiation noise from electric power facilities interferes with broadcasting or communication signals. It is required to monitor radio frequencies of surrounding environment to maintain broadcasting and communication quality.
RF plasma is used for semiconductor manufacturing processes such as Dry Etching, CVD and Sputtering. Efficient RF signal transmission is required in the systems to make plasma condition stabilized. It is important to monitor power and impedance in system operating status for boosting yield on semiconductor manufacturing.
Two RF input channel with phase sync. can contribute to high-energy research.
