For more details, refer to "Setting Up Remote Control" in the user manual.
5.2.4 Ref. In / Ref. Out
The Ref. In connectors are used to provide an external reference signal to the
R&S FPL1000.
The Ref. Out connectors can be used to provide a reference signal from the
R&S FPL1000 to other devices that are connected to this instrument.
Various connectors are provided for different reference signals:
Connector Reference signal Usage
Ref. In 10 MHz
10 dBm
To provide an external reference signal on the
R&S FPL1000.
Ref. Out 10 MHz
10 dBm
To provide the internal reference signal from the
R&S FPL1000 to another device continuously.
For the R&S FPL1000, this is also used to pro-
vide the optional OCXO reference signal to
another device.
5.2.5 Trigger In
Use the female Trigger In connector to input an external trigger or gate data.
Thus, you can control the measurement using an external signal. The voltage
level is 1.4 V. The typical input impedance is 10 kΩ.
5.2.6 Noise Source Control
The Noise Source Control female connector is used to provide the supply voltage
for an external noise source. For example, use it to measure the noise figure and
gain of amplifiers and frequency converting devices.
This connector is only available if the R&S FPL1-B5 option is installed.
Conventional noise sources require a voltage of +28 V to be switched on and 0 V
to be switched off. The output supports a maximum load of 100 mA.
