Attention!
The maximum input levels at all test ports according to the front panel labeling or
the data sheet must not be exceeded.
In addition, the maximum input voltages of the other input connectors at the front
and rear panel must not be exceeded.
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.
Attention!
The maximum RF input levels at all front panel jumpers inputs according to the
front panel labeling or the data sheet must not be exceeded.
In addition, it is important that the signal fed in at the jumper input connectors
contains no DC offset, as this may impair the measurements and even cause
damage to the instrument.
