Front Panel Connections
RF OUT
This is the 50Ω generator output. The maximum output is 500mVrms (+7dBm) into 50Ω. It can
tolerate a short circuit indefinitely.
Do not apply an external voltage to this output.
The Type N connector is a precision component that should be protected from excessive wear to
ensure that its RF characteristics (impedance and VSWR) are accurately maintained. If the
instrument is used in a manner that demands many connections/disconnections to and from the
RF OUT it is good practice to fit a male–to–female adaptor to the socket which can be replaced
periodically.
MOD IN
This is the external FM input. Input frequency range is 300Hz to 50kHz and input impedance is
nominally 100kΩ.
Do not apply external voltages exceeding ± 10V peak to this input.
Rear Panel Connections
RS232
9-pin D-connector compatible with the Thurlby Thandar ARC (Addressable RS232 Chain) system.
The pin connections are shown below:

Pins 2, 3 and 5 may be used as a conventional RS232 interface with XON/XOFF handshaking.
Pins 7,8 and 9 are additionally used when the instrument is connected to the ARC system. Signal
grounds are connected to instrument ground. The ARC address is set from the front panel using
the Utilities menu.
GPIB (IEEE-488)
The GPIB interface is an option. It is not isolated; the GPIB signal grounds are connected to the
instrument ground.
The implemented subsets are:
The GPIB address is set from the front panel using the Utilities menu.
