1.4.6 BNC Connectors
The BNC connectors are located on the left side of the R&S ZVH behind a protective
cap.
You can configure both BNC connectors for various applications. The name of the
connector is printed on the insides of the protective caps.
1.4.6.1 EXT TRIG / EXT REF
The first (upper) BNC connector supports an external trigger source or an external
reference signal.
The external trigger is only for input configuration. It controls the start of a
measurement and has to be selected in the "Sweep" menu. The trigger threshold is
similar to that of TTL signals.
The 10 MHz reference signal that you can apply is used for frequency synchronization.
The level of the reference signal must be larger than 0 dBm. When the BNC connector
is configured for the external reference but no reference signal is present, the
R&S ZVH displays an appropriate message. Thus, measurements without a valid
reference can be avoided.

1.4.6.2 BIAS Port 1 / BIAS Port 2
When you use the BNC connectors as BIAS ports, the two BNC connectors are direct
current inputs.
Active equipment under test can be supplied with power via the BIAS Port 1 and BIAS
Port 2 direct current inputs. Direct current is supplied with the assistance of a suitable
power adapter (600 mA max. / 50 V max.).
