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.
