Note:
The rear BNC connectors are available for the following functions:
10 MHz REF. IN/OUT; External 10 MHz refernce clock may be connected
at this connector. TTL level. At the default setting the internal reference is
connected to the internal sample clock generator and the output is a 10 MHz
internal oscillator signal.
CLOCK IN/OUT; The sample clock may be brought in from the external
source through this connector. TTL level. The clock frequency must be twice
the internal sample clock rate, i.e. 4MHz for the internal sample clock rate of
2MHz. At the default setting the internal sample clock generator is connected
to the instrument and twice the frequency of the internal sample clock is
present at the output.
SYNC TRIG OUT; The signal required for multiple unit operation to
guarantee the proper phase between the generators.
TRIG IN; The external trigger input. TTL level.
