Operation in a rack
●
Allow for sufficient air supply in the rack.
●
Make sure that there is sufficient space between the ventilation holes and the rack
casing.
2.3.5 EMI Suppression
To suppress generated Electromagnetic Interference (EMI), operate the instrument only
while it is closed, with all shielding covers fitted. Note the EMC classification in the data
sheet.
Use appropriate shielded cables to ensure successful control of electromagnetic radiation
during operation, especially for the following connector types:
●
Output connectors REF OUT1, RFx COM, RFx OUT: Use double-shielded RF cables
and terminate open cable ends with 50
Ω
.
●
USB: Use double-shielded USB cables and ensure that external USB devices comply
with EMC regulations.
●
GPIB (IEEE/IEC 625): Use a shielded GPIB cable.
●
LAN: Use CAT6 or CAT7 cables.
Observe the additional connector, cable, and cable length requirements in chapter “Inter-
faces and Connectors”.
2.3.6 Connecting the Instrument to the AC Supply
The R&S CMW500 is automatically adapted to the AC supply voltage supplied. The sup-
ply voltage must be between 100 V and 240 V with frequencies ranging from 50 Hz to 60
Hz (see also the tolerances quoted in the data sheet). The mains connector is located in
the upper left corner of the rear panel.
●
Connect the instrument to the AC power source using the AC power cable delivered
with the instrument.
The maximum power consumption of the tester depends on the installed options. The
typical power consumption is also listed in the data sheet.
The R&S CMW500 is protected by two fuses located in the fuse holder to the right of the
AC power switch; see
.
2.3.7 Power on and off
The mains connector is located at the bottom left corner of the rear panel.
If you have received additional cables, connect them as described in section
before switching on the instrument.
