4.2.5
Ref In
As a reference signal, you can either use the internal reference, or connect an
external one. The setup menu is used to switch between the internal and an
external reference. The REF IN female connector is used as an input for a
1-20
MHz reference signal. The required input level is 0-10
dBm.
4.2.6
Ref Out
This connector can be used to provide an external reference signal (e.g. the
OCXO) to other devices that are connected to this instrument. The REF OUT
female connector can output a 10
MHz reference signal with an output level of
0
dBm.
4.2.7
GPIB Interface
The GPIB interface is in compliance with IEEE488 and SCPI. A computer for
remote control can be connected via this interface. To set up the connection, a
shielded cable is recommended.
For more information, refer to the user manual.
4.2.8
Trigger Output
The female BNC connector can be used to provide a signal to another device.
The signal is TTL compatible (0
V / 5
V).
You can control the trigger output with the functionality provided in the "In-/
Output" menu ([INPUT/OUTPUT] key).
The trigger output also controls signals by the frequency mask trigger available in
realtime mode (R&S
ESR-K55).
4.2.9
IF / Video
The female BNC connector can be used for various outputs:
●
Intermediate frequency (IF) output of 32 MHz
●
Video output (1
V)
