User Manual 1179.4363.02 ─ 01
The male USB connector (type B) allows you to connect the R&S
FSPN to a computer
and establish a remote control connection, for example.
All USB connectors support standard 2.0.
3.2.2.6
Sync Trigger Input and Output
The "Sync Trigger Input / Output" connectors allow you to synchronize several devices
(for example two R&S
FSPNs) with respect to the trigger signal, but also the reference
frequency. A 100
MHz signal can be output as a trigger or reference signal to another
device, and an external trigger or reference signal can be received at the input connec-
tor by the R&S
FSPN.
3.2.2.7
Aux. Port
A 9-pole SUB-D male connector used to provide low-voltage TTL control signals (max.
5
V). The output signals can be used to control external devices.
3.2.2.8
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.

3.2.2.9
OCXO
The OCXO generates a 10
MHz reference signal with a very precise frequency. If no
external signal is used, this signal is used as an internal reference. It can also be used
to synchronize other connected devices via the REF OUTPUT 10 MHz connector.
Warm-up time for OCXO
When the instrument is switched on, the OCXO requires an extended warm-up time
(see data sheet).
3.2.2.10
REF INPUT / REF OUTPUT
The REF INPUT connectors are used to provide an external reference signal to the
R&S
FSPN.
Various connectors are provided for different reference signals:
