R&S®IMS Integrated Measurement System
Off-the-shelf EMC - the one-box solution up to 3 GHz
Components
The Integrated Measurement System R&S® IMS is a complete EMS test system for compliance tests in accordance with commercial, military and automotive standards from 9 kHz to 3 GHz.
Signal generation
The analog modulation types AM, FM, φM and PM are available. The optional Generator Interlock Relay R&S® IMS-B3 makes it possible to insert a 50 Ω termination rather than the generator signal if an interlock loop is open.
Power measurement
The Power Sensor R&S® NRP-Z91 is used to measure forward and reflected power and to monitor, for example, injected current in the case of bulk current injection (BCI). A fast, wear-free PIN diode switch allows switching between forward power, reflected power and monitoring. It is also used for system calibration. Additional power sensors can also be implemented (option R&S® IMS-B7 required).
Spectrum analyzer module
If the optional Spectrum Analyzer Module R&S® IMS-B1 is added, frequencyselective power measurements can be performed. This makes it possible, for example, to take harmonic components of the amplifier into account at the 1 dB compression point. Another application is current monitoring with the BCI method in the automotive range (checking of the first five harmonics).
RF switching unit
The RF switching unit handles the switching of all R&S® IMS RF paths for up to three amplifiers. Two amplifier outputs can be switched to two different transducers (e.g. antennas, current probes) or connection points (e.g. in anechoic chambers and shielded enclosures) by means of the optional Transfer Relay R&S® IMS-B2.
Internal amplifier module
Conducted measurements can be performed using an internal amplifier module (R&S® IMS model 14), which has a frequency range of 9 kHz to 250 MHz. The minimum amplifier power of 25 W (CW lin) permits measurements with coupling/decoupling networks (CDN) at a test voltage of 10 V in accordance with EN 61000-4-6.
External amplifiers
Amplifiers with an authorized USB control (e.g. from BONN Elektronik GmbH) can be integrated into the system via plug & play. Up to three amplifiers can be controlled and connected.
Interlock
The R&S® IMS operating system supports the control of an interlock loop for monitoring security functions during the EMS measurement, e.g. door contacts and amplifier status.
EUT monitoring
To allow EUT monitoring during the EMC test, the R&S® IMS has four digital inputs. These inputs can be queried either individually or together. To allow EUT stimulation, the R&S® IMS provides four digital outputs (static values or pulse signals).
