Bi-phase modulators cover frequency bands from 0.5 to 40 GHz
A new line of bi-phase modulators includes a comprehensive selection of nine different models covering broad octave frequency bands ranging from 0.5 to 40 GHz. Bi-phase modulators take a TTL-level digital bit stream that is encoded onto the RF carrier using 2 Phase Shift Keying (2PSK) modulation, where the two phases are separated by 180°. […]
Test setup checks IEC compliance for power-line harmonics and flicker emissions
A new range of power line harmonics and flicker emissions and immunity test systems test ac-powered products for compliance with the EU Low Voltage Directive. These test systems consists of a programmable ac power source, a harmonics and flicker measurement module and one or more lumped flicker impedances. All components of the test system are […]
Multi-channel LoRa-specific 1U rackmount tester handles transmitter/receiver signal evaluation
The GWInstek C-1200 LoRa Tester is a one-box tester that incorporates a multitude of LoRa transmit and receive tests. The C-1200 provides transmitter tests that include spectrum analysis, time domain, FEI (Frequency Error Indicator), and TOA (Time-On-Air). LoRa Receiver tests include sensitivity, BER (Bit Error Rate), and PER (Packet Error Rate). In addition to sub-gigahertz […]
Testing regimes for the new frequencies and features of 5G
Measurements taking place in pre-commercial 5G network trials provide new insights and overcome uncertainties before the technology’s formal launch. By Rohde&Schwarz The 3rd Generation Partnership Project (3GPP) defined fifth-generation (5G) cellular technology in Release 15, which updated mission-critical (MC) communications and MC service functions, to meet the International Telecommunication Union’s IMT-2020 performance requirements. IMT-2020 laid […]
The complexity of wireless receiver testing
Eric Hsu | Keysight Technologies, Inc. The demand for wireless communications now challenges the physical limitations of today’s wireless communications systems. Interference can easily arise when systems operate in a crowded wireless environment using a shared spectrum. Signal congestion makes the process of designing, testing, and isolating system problems more complex. In the next few […]
