### Front Panel Jumpers

3 pairs of BNC connectors for each test port. The front panel jumpers are available as option R&S ZVA<n>-B16, Direct Generator/Receiver Access. For detailed ordering information and application examples refer to the data sheet.

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.
