●
Before each measurement, check the instrument for proper operation
using a known signal source or sample.
●
Signal levels at the input connectors are all within the specified ranges.
●
Signal outputs are correctly connected and are not overloaded.
If it is assumed that a safe operation is no longer possible, the instrument
must be shut down and secured against any unintended operation.
Note: To disconnect from the mains, unplug the IEC socket on the back
panel.
Also remove the instrument from operation if:
●
The instrument shows visible damage
●
The instrument includes loose parts
●
The cables show damage
●
The fuse holder shows damage
●
The instrument is no longer working
– After an extended period of storage under unfavorable conditions (e.g. out-
doors or in damp rooms)
– After rough handling during transport (e.g. packaging that does not meet
the minimum requirements by post office, railway or forwarding agency)
EMI impact on measurement results
Electromagnetic interference (EMI) can affect the measurement results.
To suppress the generated electromagnetic interference (EMI):
●
Use suitable shielded cables of high quality which must not exceed the
maximum cable length, and must not be outside of buildings.
We recommend that you use double-shielded data cables with a length
of 3 m at a maximum, e.g. the IEEE bus data cable R&S HZ72 (GPIB-
cable 2 m, Order No. 3594.4269.02).
●
Always terminate open cable ends.
●
Note the EMC classification in the data sheet.
