Multiple analyzers in one instrument

The Anritsu MS2090A Field Master Pro series analyzers have many operating modes: classic scanning spectrum analyzer, real-time spectrum analyzer (RTSA), interference hunter, channel scanner, 5G analyzer, LTE analyzer, WCDMA analyzer, pulse analyzer, electromagnetic field meter, high accuracy power meter, antenna analyzer and others. The operating mode is selected in the analyzer's main menu. Each mode supports its own types of measurements and the corresponding menu structure. The main capabilities of these modes are shown below on this page.

Selecting the operating mode on the Anritsu MS2090A analyzer screen — Main operating modes of the Anritsu MS2090A series spectrum analyzer.

Classic spectrum analysis mode

The large display on the Anritsu MS2090A Field Master Pro analyzers allows you to simultaneously view up to six spectral lines (traces), each of which can use its own detector type and its own accumulation or averaging mode.

The screenshot below shows a single RF signal with a 50 MHz bandwidth, but measured in three different ways. The first graph (yellow) uses the peak detector and the maximum accumulation mode. The second graph (green) uses the average detector and the 10-measurement averaging mode. The third graph (blue) uses the peak detector and the minimum accumulation mode. This way, you can easily see the range of the signal amplitude variation.

To measure the spectral characteristics of radio signals, you can activate up to 12 markers and a table of values containing detailed information about each marker. There are four types of markers: normal, delta marker, noise marker and frequency counter marker. The user also has the means to automate work with markers: search for maximum, minimum, placement of markers on harmonics, etc.

This screenshot shows a section of the spectrum in the range from 0 Hz to 1 GHz. There are five markers at the peaks of the radio signals found: four regular markers and one delta marker. The exact values of the frequencies and powers of each marker are given in the table at the bottom of the analyzer screen.

All Anritsu MS2090A Field Master Pro series signal and spectrum analyzers support the display of a continuous sequence of spectra as a spectrogram as standard. This mode, which is also called a time-frequency diagram, is very useful for finding intermittent signal sources or interference, as well as for tracking the amplitude and frequency drift of radio sources.

This screenshot from the Anritsu MS2090A analyzer shows a 122 MHz spectrum section. At the bottom of the screen is a spectrogram containing 130 consecutive measurements of the spectrum of this section. The total measurement time of 130 spectra in this case is 4.54 seconds. There are two markers on the spectrogram: C1 (on the 41st spectrum) and C2 (on the 88th spectrum). The two spectra corresponding to these markers are shown at the top of the screen (yellow for C1 and green for C2).

Real-time spectrum analysis

The MS2090A series models are standard scanning spectrum analyzers. With the MS2090A-0199 option, they gain the ability to analyze the spectrum in real time with a bandwidth of 20 MHz. With the MS2090A-0199 and MS2090A-0103 options, the real-time analysis bandwidth is 55 MHz. And with the MS2090A-0199 and MS2090A-0104 options, the real-time analysis bandwidth is 110 MHz.

This mode is useful for analyzing rapidly changing signals such as frequency hopping, detecting short pulses lasting a few microseconds or searching for sources of transient interference. This mode is also used for TIP (technical information protection) tasks.

As an example, the figure below shows a screenshot of the MS2090A screen analyzing the spectrum in the frequency range from 2.4 GHz to 2.5 GHz. The screenshot clearly shows the structure of the Bluetooth scanning signal transmitted from the smartphone in the search mode for other Bluetooth devices. A Wi-Fi signal is transmitted in the same frequency range, in the center of which there is stationary interference (a small green peak with a red dot in the center).

Limit lines can be used to further automate spectrum analysis in both classic and real-time modes. When the measured signal crosses the limit line, the analyzer can save the measurement results to memory or perform another action. This is useful in the case of intermittent interference, when the user can set the limit line and automatically capture the required information when it is crossed. This function is also useful for incoming control of radio frequency devices for compliance with specified parameters. For example, this screenshot shows a limit line consisting of nineteen segments (the green line along the upper edge of the spectrum).

Search for interference sources

The presence of the MS2090A-0024 option and the additional Anritsu MA2700A Interference Hunter antenna holder greatly simplifies the search for radio signal sources. The Anritsu MA2700A antenna holder connects to a spectrum analyzer via USB, contains a GPS receiver, an electronic compass and a preamplifier with an on/off button. This photo shows the exterior of the MA2700A Interference Hunter along with the MS2090A series analyzer.

Option MS2090A-0024 includes AM/FM audio demodulation of interference signals, audio signal for interference direction finding and geolocation of interference sources on a digital map. This screenshot shows the analyzer screen with a map of the area, on which the location of the signal source is marked using three bearings.

Channel scanner

The presence of the MS2090A-0027 option allows you to work with the analyzer in channel scanner mode, with which you can display the power of up to 20 channels on one screen or up to 60 channels on several pages. Channels can have a regular frequency increment or can be set to any combination of frequencies and spans. A screenshot of the analyzer screen in channel scanner mode is shown below.

5G network analysis

If the Anritsu MS2090A analyzer has the MS2090A-0888 option installed, then the ability to demodulate and analyze fifth-generation wireless networks (5G) signals is activated. In this mode, the Anritsu MS2090A spectrum analyzer can measure all key parameters of wireless radio signals, which allows you to optimize your network structure and quickly identify and fix problems that arise during its operation.

One of the features of 5G networks is the use of multi-sector antennas and dynamic coverage optimization technology (Beamforming). The Anritsu MS2090A series analyzers can simultaneously measure key parameters of up to 64 radio beams, which is more than enough to solve any practical problems. This screenshot shows the MS2090A screen, which displays the SS-RSRP, SS-RSRQ, SS-SINR, and SS-RSSI parameters of eight individual beams of sector number 560.

LTE network analysis

If the Anritsu MS2090A analyzer has the MS2090A-0883 option installed, then the ability to demodulate and analyze LTE FDD/TDD wireless network signals is activated. These measurements are performed to increase the speed and reliability of data transmission by monitoring and adjusting key network parameters. This screenshot shows one such measurement: checking the modulation quality of the transmitted signal with the display of the constellation diagram.

Case design

On the side of the Anritsu MS2090A series analyzer case, under the protective cover, are various communication connectors: a USB 3.0 port, a USB Type C port, a 1G Ethernet port, a PCIe port for streaming data, a slot for installing a microSD card, a standard audio output for headphones, and a connector for connecting an external power supply.

All RF connectors of the MS2090A series analyzers are located on the top of the device case. This is very convenient when working on site: the connected cables do not interfere with the operator. The 9 GHz, 14 GHz and 20 GHz models use a standard N(f) input connector. The 26.5 GHz, 32 GHz and 43.5 GHz models use a ruggedized high-frequency K(m) connector. And the 54 GHz model uses a ruggedized high-frequency V(m) connector. Also on the top side of the case are: an input for connecting a GPS antenna, an output of a constant voltage source (Bias Voltage), an input and output of a reference frequency signal, an input and output of a synchronization signal, an output of an intermediate frequency (IF Out) and two USB ports for connecting flash drives.
