Note: When the 9400A is remotely read out, the entire memory content of
32,000 words is available at all time base speeds for single shot and
roll modes. 24,000 samples are available for all RIS settings except at
I and 2 psec/div,
when 24,800 and 25,000 samples respectively
are
available.

EXTERNAL
Trigger
Input (24) - This BNC connector
input accepts
external trigger signal of up to 250 V (DC + peak AC). Input impedance
is 1M~ in parallel with < 30 pF. The triggering frequency is >200 MHz.
Trigger SOURCE (23) - Selects the trigger signal source as follows:
CHAN 1 - Selects the Channel i input signal.
CHAN 2 - Selects the Channel 2 input signal.
LINE - Selects the line voltage powering the oscilloscope in order
to provide a stable display of signals synchronous with the power
line.
