Quick Start Guide for 3680A/B Cable and Antenna Analyzer
with other external instrument; output 10MHz reference signal inner Analyzer for the use of external
instrument.
3. Port 1: or know as test port, is used in cable or antenna test. Characteristic impedance is 50Ω, N-type
female port.
In order to protect the instrument better, the test port of instrument provides
some identification symbols, users shall pay attention on their meanings to
avoid permanent damage to the instruments.
Detailed description of instrument symbols are as described in Section 2.5.4.

keyboard.
2.5.4 Instrument symbol
Instrument symbol shown in the picture (yellow label) means that the maximum input power of test port 1
is +27dBm; the maximum input DC level is 25VDC. Do not connect signals beyond this range to the port
in use, which could burn the instrument!
2.6 Battery
3680A/B is equipped with a rechargeable lithium-ion battery with a large capacity with operating time of
up to more than 8 hours for 3680A and 4 hours for 3680B.
In order to assure the service life, the battery
shall be taken out of the battery compartment in transport and long-term storage.
Buying stand-by
batteries of the same model with the original one is recommended if long-time field test is performed.
The mounting or replacement of the battery of 3680A/B is easily performed as shown in Figure 2.4.
