MAIN OUT
MAIN OUT is a 50Ω output. To maintain waveform integrity only high quality 50Ω connecting
cables should be used and the receiving end should be terminated with a 50Ω load.
Do not short-circuit or apply external voltages to this output.
AUX OUT
The AUXiliary output provides a fixed level pulse output with the same frequency and symmetry
as MAIN OUT and capable of driving up to 4 standard TTL loads.
EXT SWEEP, AM/FM IN
An external signal applied to the EXT SWEEP input can be selected to modulate either the
frequency or amplitude of the generator output.
Do not apply external voltages exceeding ± 10V.
RS232
The RS232 interface permits remote control using the optional PC420 Windows software.
The 9-way D-type socket on the generator has the following pin-out and should be connected to
the PC's serial port using a 9-way cable with all connections made.
Signal ground is connected to instrument safety ground.
To ensure compliance with EMC legislation use only screened cable assemblies with screened
connectors when connecting to other equipment.
