Baseband analyser for chipset development
Baseband analyser is exactly tailored to the requirements of chipset development for mobile phones and basestations.
The new R and S FMU36 baseband analyser is exactly tailored to the requirements of chipset development for mobile phones and base stations. The cost-efficient instrument with a frequency range up to 36MHz performs the measurement ahead of the RF signal and measures the I/Q signals in the baseband. Spectrum and vector signal analysis for WLAN or 3GPP FDD, for example, can be performed by means of probes directly on the DUT's printed board, if necessary.
For low-frequency applications such as radio transmission via RFID or measurements on ADSL modems, the RandS FMU36 features consistently high sensitivity even at very low frequencies.
The baseband analyser combines all functions in one instrument and runs without an external PC.
For use in measurement systems, it can be remote-controlled via GPIB or LAN.
By means of the R and S FMU36, developers can check the modulation quality of their circuits even at the I/Q baseband.
For this purpose, the instrument features two analog inputs that can be operated either as balanced or unbalanced.
Probes available as an accessory allow you to directly perform measurements on the connections of integrated circuits.
During measurement, all parameters that are important for the respective application are determined in the frequency, time and modulation domain.
This also includes frequency response and spectrum mask, adjacent-channel power, carrier-to-noise ratio and modulation depth.
If a weak pulsed signal is close to a strong signal, the pulsed signal can be filtered out.
With a time-capture memory of 16Msample on I and Q, the R and S FMU36 can capture long sequences.
The memory can be extended to 705Msample, if necessary.
Moreover, the RandS FMU36 comes equipped with the established RandS FSQ-K70 vector signal analyser.
Thus, you can demodulate and analyse digital signals of all common mobile radio standards such as GSM, WCDMA, CDMA2000 or Tetra down to the bit stream level.
Standard measurements such as modulation accuracy, carrier leakage or I/Q imbalance can be easily performed.
