The length of passive connecting USB cables should not exceed 1 m. The maximum current per
USB port is 500 mA.
Ground Connector
Connector providing the ground of the analyzer's supply voltage.
Attention!
Electrostatic discharge (ESD) may cause damage to the electronic components
of the DUT and the analyzer. Use the wrist strap and cord supplied with the
instrument to connect yourself to the
GND connector.
Front Panel Jumpers
3 pairs of BNC connectors for each test port. The jumpers give direct access to various RF input and
output signals. They can be used to insert external components (e.g. external signal separating
devices, power amplifiers, etc.) into the signal path in order to develop custom measurements, e.g. to
test high power devices and extend the dynamic range. If no external components are connected,
each pair of OUT/IN jumper connectors is through-connected internally.
•
The SOURCE OUT signal comes from the internal RF signal source. The SOURCE IN signal goes
to the test port. A power amplifier can be inserted between SOURCE OUT and SOURCE IN in
order to boost the test port power.
•
The REF OUT signal comes from the coupler and provides the reference signal. The REF IN signal
goes to the receiver input for the reference signal.
•
The MEAS OUT signal comes from the coupler and provides the received (measured) signal. The
SOURCE IN signal goes to the receiver input for the measured signal.
