Headphone jack
The female headphone jack allows you to connect headphones (or external speakers)
with a miniature jack plug.
You can control the output voltage with the volume control integrated into the firmware.
Refer to the user manual for details.
If you connect headphones or external speakers, the R&S FPC automatically turns off
the internal speaker.
Note the safety information provided in "Connecting headphones" on page 9.
USB ports (type A)
The two USB 2.0 ports on the front panel (type A) allow you to connect devices like
memory sticks.
Function keys and alphanumeric keypad
The function keys provide access to the measurement settings and functions. The
alphanumeric keypad allows you to enter alphanumeric data if necessary.
Refer to the user manual for a comprehensive description of the function keys.
Softkeys
The softkeys allow you to access measurement settings and functions.
Softkeys are dynamic. A different list of softkeys is displayed depending on the
selected function key. A list of softkeys for a certain function key is also called a menu.
Softkeys can either perform a specific function or open a dialog box.
Refer to the user manual for a comprehensive description of the function keys.
RF Input
The RF input with an impedance of 50 Ω allows you to connect a DUT to the
R&S FPC. Typically, you connect the DUT with a cable and an appropriate connector
(for example a male N connector).
The frequency range of the RF input is specified in the datasheet.
The attenuation range is between 0 dB and 40 dB.

Power supply
The AC power supply and main power switch are located in a unit on the rear panel of
the instrument.
The main power switch has the following states.
●Position "1": The instrument is supplied with power.
●Position "0": The instrument is disconnected from the power supply.
Trigger input / external reference
This female BNC connector allows you to connect an external trigger signal or an
external reference signal.
When you are using the connector as a trigger input, you can trigger measurements
with an external trigger. For more information about triggered measurements, refer to
the user manual.
Alternatively, you can use the connector to connect a 10 MHz reference signal to syn-
chronize the frequency with the external reference. Note that the reference signal must
be stronger than 0 dBm.
