RF-Power-Meter

The PMS 1084 is in the standard version a 2-channel RF-Power Meter for the frequency range from 100 kHz up to 6 GHz or from 10 kHz to 500 MHz (PMS 1084 B). The measuring range reaches from –60 dBm to +20 dBm. It is possible to upgrade the PMS 1084 up to max. 4 measuring channels at any time. The measured values can be displayed via a software which is included in the delivery or via the control software of an automated test system. For the integration of the PMS 1084 into a remote-controlled test system it is equipped with serial and USB interface. Hence the PMS 1084 is very good suitable for the automated measurement of forward and reverse power in immunity test systems acc. to IEC/EN 61000-4-3 / -6. It is available for the installation into 19”-rack or as stand-alone unit.

Relay Switching Unit

The RSU Relay Switching Unit is applicable for all fields of RF- and EMC measurements to switch (manual or remote-controlled) from one input to 2 or 3 outputs. Typical applications in measuring systems are changeover switching between different amplifiers, antennas or power meters. This does also prevent circuit faults due to wrong cabling. By means of a selector switch on the front panel of the RSU it is possible to work in manual mode or remote- control mode via the RS232, USB or GPIB interface.

The input/output connectors of the relays are installed on the rear panel of the RSU, this allows an easy cabling when or where the RSU is mounted into a 19”-rack. A RSU can be equipped with a maximum of 4 relays with 2 or 3 outputs. The quantity of relays with 2 or respectively 3 outputs is variable. The delivery includes a Windows software for easy remote-controlled applications. However for extensive systems it is recommended to integrate the RSU driver into the system control software.

The easy to follow commands for RS232 and GPIB interfaces are listed in the user manual.
