FRA 51602
■ 10 MHz REF OUT
This connector outputs the clock signal that is actually used as the reference clock by the instrument.
When the instrument is operating on an external 10 MHz reference clock (input to 10 MHz REF IN ), the
frequency that is output is the same as the frequency of the external reference clock.
Output voltage : 1 Vp-p / 50 Ω
Output waveform : Square
Output impedance : 50 Ω (nominal), AC coupling
Connector : Rear panel, BNC connector
！
CAUTION
•
Applying an external signal to the 10 MHz REF OUT connector will damage the
internal circuits. Never input a signal to the 10 MHz REF OUT connector.
•
The BNC ground of the 10 MHz REF OUT connector is connected to the enclosure.
Do not connect signals for which there is a difference in potential relative to the
enclosure. Doing so may damage the instrument.
