Key facts

  • Monitoring and TDOA from 8 kHz to 8 GHz (up to 20 GHz with R&S®CS-MC20)
  • AoA direction finding from 20 MHz to 8 GHz (depending on DF antenna)
  • Compact outdoor housing with integrated PC, hard disk and wireless connectivity
  • Signal measurements in line with ITU Recommendations (optional)
  • Streaming of I/Q data (optional) with up to 40 MHz real-time bandwidth

Outdoor spectrum monitoring and radiolocation solution

The R&S®UMS400 universal monitoring system can be used for spectrum monitoring and radiolocation from 8 kHz to 8 GHz and can be extended up to 20 GHz with the R&S®CS-MC20 microwave converter

The ever-increasing frequency range of wireless communications services calls for monitoring stations up to 8 GHz, in some cases even up to 20 GHz. Typically, this requires a monitoring sensor installed close to the antenna(s) in order to keep cable losses as low as possible for highest sensitivity. This is possible for both the R&S®UMS400 and R&S®CS-MC20, thanks to an outdoor housing.

Features & benefits

Frequency range extension

The frequency range of the R&S®UMS400 can be extended up to 20 GHz

The frequency range of the R&S®UMS400 can be extended up to 20 GHz with the R&S®CS-MC20 microwave converter. The compact outdoor housing means the R&S®CS-MC20 can be installed together with the R&S®UMS400 using the R&S®CS-OMK outdoor mounting kit.

Support of radiolocation

The R&S®UMS400 supports the time difference of arrival (TDOA) and angle of arrival (AoA) radiolocation as option

The R&S®UMS400 and the R&S®CS-TSA timestamp accuracy option support accurate radiolocation with the time difference on arrival (TDOA) method in combination with R&S®ARGUS spectrum monitoring software.
The R&S®UMS400 can be upgraded to direction finding (DF) with the R&S®CS-DF direction finding option in combination with an Rohde & Schwarz DF antenna (see product brochure for details).

Support of wideband signals

Monitoring and streaming of I/Q data (optional) with a real-time bandwidth of 40 MHz

The R&S®UMS400 supports the demodulation of signals with a bandwidth up to 40 MHz. Streaming of I/Q data is available by means of the R&S®CS-U10G 10G Ethernet interface as option.

Compliant signal measurements

The R&S®UMS400 supports the measurement of signals in line with ITU Recommendations

The R&S®UMS400 supports signal measurements in line with ITU Recommendations and can be integrated into monitoring systems running the R&S®ARGUS spectrum monitoring software or other control software easily thanks to its open interface.

Integrated antenna switch

The R&S®UMS400 features an antenna switch for two monitoring antennas

Both antenna connectors can be equipped with an R&S®CS-UDC DC feed to directly support active antennas.
When used with the R&S®CS-MC20 microwave downconverter is used, it occupies one of the antenna connectors.
