Power specifications
Power is provided to the TEM Module by the connected 5800v2 test instrument. Battery
life varies depending on the type and duration of the tests that you conduct; the 5800v2
may also be powered using the AC Adapter that shipped with the test instrument.
Connector specifications
The TEM Module connector panel provides an SMA connector for a GNSS Antenna,
and five SMB connectors for 1 PPS and 10 MHz input and output signals.
SMA connector
The SMA connector (labeled
GNSS Antenna
) allows you to connect a GNSS Antenna
to the TEM Module. The connector supports an input signal level ranging from 5 dB to
30 dB.
For optimal performance, maintain gain between 5 dB and 20 dB
.
SMB connectors
provides specifications for each SMB connector.
•
All SMB connectors use 3.3V CMOS technology.
•
All SMB inputs are terminated with 50 Ohms to ground.
* Terminated with 50 Ohms.
** Unterminated.
