The equivalent isotropic radiated power values gathered are evaluated with respect to a threshold value, thereby determining at least one subset of the equivalent isotropic radiated power values. In addition, a method of performing spurious emission measurements is described.
The present disclosure relates to a method and a device for analyzing and/or visualizing a wireless communication by user equipment. The method includes receiving a log file which includes information on the wireless communication; and analyzing at least a part of the log file to determine: a number of uplink and/or downlink cells which were aggregated during the wireless communication, a numerology for each uplink and/or downlink cell. The numerology defines a number and/or a duration of time slots of the uplink and/or downlink cell, and a number of scheduled items of each uplink and/or downlink cell. Each scheduled item is assigned to at least one time slot of the uplink and/or downlink cell. The method further includes displaying a scheduling view which shows the time slots of at least one of the number of uplink and/or downlink cells together with their assigned scheduled items in a graphical representation.
The present invention relates to an integrated circuit, in particular a photonic integrated circuit, for generating an electrical and/or optical frequency comb signal, the integrated circuit comprising: a pulse generation unit comprising an input port for receiving an optical high frequency signal. The present invention provides a Kerr-ring for the generation of an optical frequency comb signal. The use of the Kerr-ring for the optical frequency comb generation makes the integration possible. The present invention further relates to an optical system and a test and measurement device.
A gate apparatus configured to perform an XOR operation on received input signals to provide a logical output signal, y. The apparatus includes at least one first signal input adapted to receive a first input signal; and at least one second signal input adapted to receive a second input signal. At least one of the received input signals is split into a first split signal portion fed to a photo diode to generate an electrical photocurrent supplied to a junction node, and a second split signal portion combined with at least a signal portion of the other signal received at the second signal input to generate a combined optical output signal supplied to an electro-optical modulator to provide the logical output signal, y. The electro-optical modulator is driven by a photocurrent processing unit having an input connected to the junction node.

SIGNAL PROCESSING METHOD, MEASUREMENT INSTRUMENT AND MEASUREMENT SYSTEM
A signal processing method is provided for processing a digital input signal. The method may be carried out by a measurement instrument. The measurement instrument includes a signal input, a measurement circuit, and an analysis circuit. The signal processing method includes the steps of: receiving a digital input signal from a device under test; capturing a first number N1 of IQ measurement sets based on the received digital input signal, wherein each IQ measurement set comprises a plurality of IQ measurement points; determining an IQ average based on the captured IQ measurement sets, thereby obtaining an averaged signal; determining a second number N2 of noise vectors based on the averaged signal and based on the captured IQ measurement sets; and averaging over the determined noise vectors, thereby obtaining an averaged noise vector.
