Chapter 2 Measurement Preparations
34
To apply external signals output from a near-mag-
netic field probe or antenna (excluding those from
the 9741) to the instrument, connect the signals to
the BNC input terminal.
The level in each frequency band can be checked
or recorded in the same way as with the 9741.
Input to the BNC input terminal is effective when
the instrument is not connected to the 9741.
The measuring range is the same as for input from
the 9741 (0 to -50 dBV).
2.5 Connecting Signals to the BNC
Input Terminal
Note the following maximum input voltage
and maximum rated voltage to earth of the
BNC input terminal. If their voltages are
exceeded, this device will be damaged and
personal injury will result. Therefore, do not
perform measurement in this case.
Maximum input voltage: 5 V
PEAK
Maximum rated voltage to earth: 5 V
When disconnecting the BNC connector, be sure
to release the lock before pulling off the connector.
Forcibly pulling the connector without releasing the
lock, or pulling on the cable, can damage the con-
nector.
