Outline

The real time IQ data recorder system MQ5300 is a system that combines a signal analyzer unit and a control analysis unit. RF signals can be continuously recorded as IQ data for a long time and played back or analyzed using software.

Our signal analyzer (MSA538 or MSA558) is built into the signal analyzer unit.

Features

Equipped with a large-capacity SSD, it can record real-time IQ data for up to 24 hours.
The frequency span can be measured collectively up to 100MHz. *When operating 5 signal analyzers in parallel
It is possible to measure different frequency bands that are not continuous (two-way communication by FDD, etc.) at the same time. *When multiple signal analyzers are configured
The spectrum can be displayed in real time even during IQ data recording.
There are two measurement frequencies depending on the built-in signal analyzer. 20kHz to 3.3GHz (MSA538) or 8.5GHz (MSA558)
The recorded IQ data can be easily played back and analyzed using the application software (MAS550).

Setup Image

Application Software MAS550

Recording screen

Make basic settings for the signal analyzer, threshold settings, and recording start / stop conditions. Up to 5 units can be set collectively or individually.

Main functions

Collective or individual setting of measurement conditions
Threshold setting (for frequency mask and UP / DOWN judgment)
Recording time setting
Start / stop simultaneous or individual recording

Playback / Analysis screen

The recorded IQ data can be displayed spectrogramically, and the waveform in the specified range can be played back and analyzed.

Main functions

Waveform display: Select from 4 types
Spectrum, overwrite, power vs. time, frequency vs. time
Audio demodulation of AM and FM signals
CSV output of IQ data
Signal search function: Threshold and time specification

Measurement example

Example 1. Measurement of up to 100MHz span

Carrier frequency interference and interference wave measurement, etc.

It is possible to accurately capture rare burst signals and hopping signals.
You can grasp the frequency of signal generation.

Example 2. Record real time IQ data for a long time

DFS function measurement of 5GHz band radio equipment, etc.

Measurements can be made at a maximum of 100 MHz span.
Up to 30us / frame can capture weather radar signals.
Frequency transitions can be monitored.

Example 3. Simultaneous measurement of different frequency bands

Measurement of two-way communication in wireless systems, etc.

Simultaneous recording of FDD system or different frequency bands is possible. (Max. 20MHz span/CH)
It can be used for stationary measurement and mobile electrical measurement such as LTE and ETC / DSRC.

Example 4. Real time spectrum display during IQ data recording

Illegal radio wave monitorin

You can check the spectrum immediately on the spot.
Time axis analysis such as power vs. time and frequency vs. time can be performed.
Audio demodulation of AM signal and FM signal is possible.
