35-6200MHz RF Spectrum Analyzer w/Tracking Generator(TG 35MHz-6.2GHz model)
Arinst SSA-TG R2(TG 35MHz-6.2GHz model)
リリース初期と比較して、機能強化がはかられています。noise floor levelは、-70dBm程度から、-100dBm程度まで改善しているので、WiFi/LTEのaverage -90dBm程度の信号レベルをmax holdで、peak holdできるようになっています。下記のyoutubeの動画を見るだけでも、能力は想像できるかと思います。
（スペアナで、Windows-Based softwareで表示のnoise floor levelは、長年、-70dBm程度でした。例えば、FRA測定器ですが、FRMSなどがそうです。SSA-TG R2のリリース時のreviewもまだ、weblog内で見れますが、この時点では、-70dBm程度だったので、前は、WiFi/LTE detectionでは、HackRF ONEをお薦めしていましたが、今では、第一選択は、スペアナとしては、SSA-TG R2です。SSA-TG R2のsoftwareでの表示範囲は、80dBですが、これは、OWON XSA1032-TGや、Siglent SSA3032X Plusのような100dB範囲を超える表示でないほうが見やすい表示範囲なので、これでいいのではと思います。その代わり、level offset設定は、defaultの0dBmから、-30dBmに変更する必要が場合によりあります。最初、黄色の基線が表示されなくてもあわてないでください)
HackRF ONEでも、Wifi/LTEの信号はdetect可能で目的によっては十分な場合もありますが、SSA-TG R2のように、RF levell,frequencyのoffsetがない事に加え、TRACE機能や、Max hold機能がありません。表示機能もありますので、fieldで、HackRF ONEは、note PCとかで、テザリングして使用するなどすればもちろん、使えますが、SSA-TG R2は、bluetoothで接続できるので便利です。frequency resolutionは、0.00MHz台までなのと、tracking generatorは、signal generatorとして、stand-alone動作もしますが、方形波出力になります。tracking機能もあり、目的の周波数が見つかれば、tarcking機能の更新を停止し、TRACEとMAX HOLDの併用でfrequency/levelのoffsetを取ったうえでの監視が可能だということです。freqeuncy resolutionは、0.00MHzまでなので、さらに1Hzまでの周波数測定には、OWON XSA1032-TGや、Siglent SSA3032X Plusなどが必要になりますが、sweep timeは、frequency resolutionがあがる分、HackRF ONEや、SSA-TG R2のような更新速度にはなりません。初心者の方は、通常のスペアナをデジタルオシロのような更新速度を期待している感がありますが、意外に遅いものです。（昔は、audio領域のreal time spectrum analyzerで音声や音楽のスペクトラム解析するものがありました）ですので、HackRFONEや、SSA-TG R2のような測定器と、OWON XSA1032-TGや、Siglent SSA3032X Plusなどのような測定器は目的により、使い分け、どちらも必要です。総合的には、SSA-TG R2は、値段に見合う機能は有しています。
Keysightのreal time spectrum analyzerは、もちろん、能力的に格段ですが、価格も価格です。
SiglentのSSA3050-R/SSA3075X-R
https://int.siglent.com/products-overview/ssa3000xr/
は、Keysightに比較し、機能限定的というか、価格も安いですが、sweep timeが、1ms程度までにはなります。(sweep timeで言えば、今では、RIGOL DSA815-TGが一番、更新が遅い上に7inch displayですが、NEXT 700MHz!の基地局信号は、それなりに、max holdでなくともdtectしてきます）OWON XSA1032-TG/SSA3032X(non PLUS model)が次によくて、SSA3032X Plusが、よりいいです、その上が、SSA3050-R/SSA3075X-Rという位置づけです。
アマチュア無線での測定では、繰り返し信号が主な測定なので、どれでもいいですが、1Hzまでの周波数測定が必要なので、HackRF ONEや、SSA-TG R2では、frequency resplutionが悪いことや測定周波数範囲で、HF帯がはずれている(up-converterを使えばいいですが）ので、通常のスペアナで補完します。
4機種すべてをお取り扱いします。
Actually what you can do,for instance......
You can search for smartphones relevant signals.(now the noise floor level is below -100dBm,feasible searching the peaks with max hold mode)

Arinst SSA-TG R2
(Details)
Arinst SSA-TG R2 is a portable panoramic spectrum analyzer designed to display signal spectrums in the frequency range from 35 to 6200 MHz.
The analyzer finds the amplitude and frequency of spectral components of the analyzed process. Spectrum analyzer can operate with signals for all widely used technologies: Wi-Fi, 2G, 3G, 4G, LTE, CDMA, DCS, GSM, GPRS, GLONASS and others.
Another important feature is the presence of additional capabilities of the tracking generator, which makes it possible to measure the frequency response of passive or active devices, for example filters or amplifiers. The software allows measuring SWR and return loss module. This requires an external directional coupler and a set of calibration measures.
Application
Arinst SSA-TG R2 is primarily intended for field operation. The device is rugged and light with low energy consumption. It enables service centers and maintenance teams to perform on-the-spot HF analysis for commissioning and repair works. Moreover, the spectrum analyzer is a perfect solution for repair workshops and radio amateurs.
For example, using the device you can perform the following operations:
- put an external antenna on the base station
- to conduct a rapid analysis of RF environments
- check the correct operation of the repeater cellular
- repair and adjustment of the repeater, generator, filter, etc.
- measure SWR when using an external directional coupler.
Principle of operation
The spectrum analyzer is a portable device that is connected to the measured circuit and has an independent power supply. The device has a 3.2" color resistive screen to display the signal spectrum and to control the device.
The device is controlled by one of three ways:
- by buttons and touchscreen on the device.
- by an Android powered smartphone or tablet.
- by a PC or laptop with Windows operating system
The data between the analyzer and smartphone/tablet/PC is transmitted through Bluetooth or USB-cable. The Bluetooth range is up to 10 m (Password for connecting via Bluetooth: 1234).
All the measured data is displayed in real time on the screen of the device or smartphone/tablet/PC.
You can install the analyzer software to control by smartphone or tablet from the Google Play (play.google.com/store/apps/details?id=com.arinst.ssa) or download from arinst.net/download-apk.php.
You can download the analyzer software to control by PC or laptop from arinst.net/download-apk.php.
API
There is a possibility of device control using API.
You can send the device a command to make a measurement (scanning range) with the following parameters:
- start frequency
- stop frequency
- measuring step
- the value of the attenuator
After the command completes, the device Arinst SSA-TG R2 will send the client device (microcontroller, computer, mobile device, etc.) a message containing the measured values of the amplitudes for the given frequency values. The user can record the received data to a file, database, etc.
Using this API users can customize automatic measurements and use the spectrum analyzer Arinst SSA-TG R2 in their system. The API works in any programming language that supports work with input-output ports (Java, C, C++, C#, Python, Assembler, etc.).
An example of using the API can be downloaded from arinst.net/download-apk.php.
Basic functions of the analyzer software:
- Displays the signal spectrums graphically and sets up the frequency range and reference limit.
- Sets up and manages absolute and relative (delta) markers.
- Searches one or a series (up to ten) of maximum values of the signal in the instantaneous or tracking mode.
- Sets and stores unique identifiers of the frequency ranges - domains. For instance, a domain titled «DCS UpLink» can be set for the range 1710-1785 MHz. Additionally, working frequency domains can be set for each operator. This option considerably facilitates the HF analysis and identification for the signals of conventional technologies.
- Has pre-set domains and is able to store the domains in a file and share them with other devices to control the spectrum analyzers Arinst SSA-TG.
- Has the tracing mode that generates a signal spectrum averaged by a number of measurements. In addition to the average spectrum, extreme values and moving average values can be displayed as well.
- Stores the settings for the spectrum scanning (band limits, attenuator value and others) for a quick and easy switching into the required measurement mode.
- Stores the spectrum signal with markers for later analysis. Then the stored graph can be opened in any Android device with the application «Arinst SSA» (in this event you don’t need to have the spectrum analyzer at hand) or use the table editor to convert the graph into the required type of data display.
- Simultaneous display of several selected frequency bands.
- The function of the tracking generator for measuring the amplitude-frequency characteristics of filters, amplifiers and antennas.

- HF adapter SMA(male)-SMA(female) to protect the HF connector from wear-and-tear (2 pcs)
- USB – mini-USB cable to charge the device and for data transmission
Items not included in the box:
- Smartphone or tablet under the Android’s 4.0.3 control or higher. Use your Android powered device in order to control the equipment. The device is implemented in one body, while the equipment for its control is built in another. It has been done in order to make the spectrum analyzer much simpler and more available. Also, use your laptop or computer for controlling the device.
- External attenuation network. The maximum measured input power, which is supplied to the device, is limited by +5 dBm. If it is necessary to measure a larger value, each user of the device has to select the necessary attenuators on one’s own.
- Set of the super-high frequency adapters.
Limitations
The spectrum analyzer Arinst SSA-TG R2 is not a measure gauge, as it does not have an approved pattern of the measuring equipment. The approval of pattern of the measuring equipment has had a negative effect on the availability and price of the device. For this reason the spectrum analyzer is officially considered a field indicator. However, the device fully meets all technical requirements. Each device is calibrated against the power and frequency.
