    On-Orbit Satellite RF Measurements

    To ensure proper performance in satellite transponders in the payload, on-orbit measurements must be made as part of maintenance. This app note focuses on satellite post-launch or on-orbit measurements, and monitoring strategies used for satellite functionality checks when running maintenance routines.

    An Introduction To Practical Real-Time Spectrum Analysis

    This application note provides an introduction to the practical uses of RTSAs to reveal important information about the performance of RF/microwave components, track down sources of interference, and monitor the spectrum for activity and security threats.

  • Calculating VNA Measurement Accuracy Vector Network Analyzers (VNA) are your primary resource when analyzing and characterizing systems and components for RF and Microwave measurements. They are regarded as accurate measuring instruments, however, quantifying the accuracy performance of a VNA in a specific application can be challenging. VNA specifications are a starting point; but, they are based upon very specific calibration and measurement conditions, which are not applicable for many applications. The Anritsu Exact Uncertainty program is available to help you obtain the uncertainty data that is appropriate for your specific application.
  • Measure Group Delay Without LO Access
    Measure Group Delay Without LO Access

    In order to operate in a satisfactory matter, a mixer needs to have well controlled amplitude, phase response, and group delay. Constant group delay is especially important in wireless and satellite communications systems and in applications involving high target resolution in surveillance systems. When mixers are used to measure group delay in frequency converters, some setbacks can occur if the local oscillator isn’t accessible...

Microwave USB Power Sensor (MA24105A) Microwave USB Power Sensor (MA24105A)

The Anritsu MA24105A Inline Peak Power Sensor is designed to take accurate average power measurements from 2 mW to 150 W and peak power measurements from 2 W  to 300 W over the frequency range of  350 MHz to 4 GHz. The sensor employs a “dual path” architecture that enables True-RMS measurements over the entire frequency and dynamic range allowing users to measure CW, multi-tone and digitally modulated signals such as LTE, LTE-TDD, GSM/EDGE, CDMA, W-CDMA, WiMAX, TD-SCDMA, WLAN, and LTE. The forward direction path also include a 4 MHz bandwidth channel that has peak and comparator/integrator circuits that add measurement functions such as PEP power, crest factor, CCDF, and burst average power. Another detection circuit on the reverse direction adds reverse power measurement capabilities including reverse power, reflection coefficient (magnitude), return-loss, and SWR. The presence of a micro-controller along with signal conditioning circuitry, ADC, and power supply in the sensor makes it a complete miniature power meter.

Spectrum Analyzer for RF and Wireless Testing and Production: DSA800 Series Spectrum Analyzer for RF and Wireless Testing and Production: DSA800 Series

The DSA800 series of spectrum analyzers collectively covers the 9 kHz to 1.5, 3.2, or 7.5 GHz frequency range. These systems feature a widescreen display, a compact design, and a simplified interface, making it ideal for benchtop or field apps in RF and wireless testing and production. The analyzers employ a Rigol digital IF filter to allow for smaller bandwidth settings and a reduction in displayed noise levels.

Synthesized Signal Generators:  4 GHz To 20 GHz Synthesized Signal Generators: 4 GHz To 20 GHz
The Lab Brick LMS Signal Generator series of USB-compatible synthesized signal generators cover the X-band frequency from 4 GHz to 20 GHz with low phase noise, fast 100 microsecond switching time, and fine 100 Hz frequency resolution. They require no additional DC supply voltage and offer advanced features such as phase continuous linear frequency sweeping, internal/external 10 MHz reference, and optional pulse modulation. GUI software can track and control several connected signal generators, simplifying multiple-signal test setups. Each device stores settings in internal memory, allowing it to power up in a specific instrument state.
