How to write antenna calibration data to a spectrum analyzer.

How to write antenna calibration data to a spectrum analyzer.

[Application Example] You can connect the antenna and spectrum analyzer that the customer has to perform electric field strength measurements.

Typically, to check the frequency and strength of radio waves transmitted from wireless communication devices, electric field strength measurements (dBμV/m) are performed. When using a spectrum analyzer (MSA400 series) in combination with our dipole antennas (M401 to M407), the calibration data (antenna gain) is already reflected, allowing for easy electric field strength measurements based on the settings of the spectrum analyzer. However, if you want to perform electric field strength measurements with an antenna you own, you will need to write the calibration data into the spectrum analyzer. By using the PC software (MAS400), you can easily write the calibration data. 【Product Introduction】 ■ Handheld Spectrum Analyzer MSA400 Series *For more details, please refer to the PDF document or feel free to contact us. 【System Configuration】 ■ Spectrum Analyzer MSA400 Series ■ USB Cable MI400 ■ PC Software *For more details, please refer to the PDF document or feel free to contact us.

[Application Example] Weather Radar Measurement Using Signal Analyzer

[Application Example] Weather Radar Measurement Using Signal Analyzer

[Application Example] An example of radio wave measurement for weather radar using the trigger function of a signal analyzer.

When attempting to measure the modulation signals of weather radar using conventional spectrum analyzers, there were instances where measurements could not be made or data was missed due to the very short pulse widths and brief occurrence times. As a solution to these challenges, by using our handheld signal analyzer (MSA558) and 5GHz band antenna (M406), it is possible to measure the radio waves of weather radar with high precision. The hardware trigger of the MSA558 (IF level, power, external) has a time resolution of up to 14.7ns, significantly reducing the chances of missing intermittent signals. Additionally, it is capable of measuring 5GHz band wireless LAN (Note 1), which can be used, for example, to verify the DFS (Dynamic Frequency Selection) function during radar detection, which requires wireless LAN communication to cease within 10 seconds and switch to another channel. [Product Introduction] ■ Signal Analyzer MSA558 ■ Portable Antenna M406 *For more details, please refer to the PDF document or feel free to contact us.

Optimization of weak signal measurement using a spectrum analyzer.

Optimization of weak signal measurement using a spectrum analyzer.

[Application Example] By optimizing the spectrum analyzer, it becomes possible to capture weak signals.

All spectrum analyzers are inevitably affected by internal noise. The average noise level defines the impact of this noise. This is a crucial factor in measuring weak signals, as it becomes impossible to measure signals that fall below the average noise level. Therefore, the key point is how to effectively keep this average noise level low. Additionally, if the signal cannot be captured even after optimizing the settings of the spectrum analyzer, measurement can be achieved by amplifying the signal. 【Product Introduction】 ■ Signal Analyzer MSA538 ■ Low Noise Amplifier MAP302 *For more details, please refer to the PDF document or feel free to contact us. 【System Configuration】 ■ Signal Analyzer MSA538 ■ Low Noise Amplifier MAP302 ■ PC Software MAS500 ■ Others (various cables, adapters, etc.) *For more details, please refer to the PDF document or feel free to contact us.

Methods to prevent measurement errors due to saturation of the spectrum analyzer.

Methods to prevent measurement errors due to saturation of the spectrum analyzer.

[Application Example] This introduces a method to prevent erroneous measurements caused by saturation due to strong power signal inputs outside the measurement frequency band in a spectrum analyzer.

When a signal above an appropriate level is applied to the 1st mixer of the spectrum analyzer, saturation occurs, leading to harmonic distortion and spurious signals, making accurate measurements impossible. Even signals outside the frequency measurement range can result in incorrect measurements if they are above an appropriate level. 【Product Introduction】 ■ Spectrum Analyzer / Signal Analyzer *For more details, please refer to the PDF document or feel free to contact us. 【System Configuration】 ■ Signal Analyzer MSA500 Series ■ Spectrum Analyzer MSA400 Series ■ Spectrum Analyzer MSA300 Series ■ Attenuators, filters, etc. *For more details, please refer to the PDF document or feel free to contact us.

[Application Example] C/N Ratio Measurement Using Channel Power Measurement

[Application Example] C/N Ratio Measurement Using Channel Power Measurement

【Application Example】 Easily measure C/N ratio with a handy spectrum analyzer. Simplify the assessment of stable reception for digital broadcasts and more.

In digital modulation communication such as digital broadcasting, the carrier-to-noise ratio (C/N ratio) is an important indicator of whether stable reception can be achieved. Deterioration of the C/N ratio leads to a rapid increase in the bit error rate (BER), making it impossible to correctly reproduce the transmitted data. Our handheld spectrum analyzer MSA438 can measure this C/N ratio using the "channel power measurement" function. ● Accurate measurement and evaluation with a full-fledged spectrum analyzer ● Easy saving of measurement results (screen, data) to USB memory, making report creation simple ● Handheld type that is easy to use on-site with simple settings (compact, lightweight, battery-operated for 4 hours), eliminating the need for commercial power outlets 【Product Introduction】 ■ Spectrum Analyzer MSA438 *For more details, please refer to the PDF document or feel free to contact us. 【System Configuration】 ■ Spectrum Analyzer MSA438 ■ Dedicated Battery MB400 *For more details, please refer to the PDF document or feel free to contact us.

Application Example: Telemetry Solution

Application Example: Telemetry Solution

[Application Example] Enables simultaneous reception of multiple channels in animal ecology research telemetry using a handheld spectrum analyzer.

In recent years, due to the increase in population of wildlife that is causing damage to agriculture and railways, telemetry transmitters are used for ecological surveys of these animals. In 2008, the "Radio Equipment for the Animal Detection Reporting System of Specified Low Power Radio Stations in the 150 MHz Band" was enacted, and the 150 MHz band was allocated for telemetry transmitters. Typically, a dedicated receiver is used for exploration, but it can only observe one channel at a time. By using the MSA338 handheld spectrum analyzer, multiple channels can be observed simultaneously, significantly improving survey efficiency. 【Product Introduction】 ■ Spectrum Analyzer MSA338 *For more details, please refer to the PDF document or feel free to contact us.
