Connection cable
Cable type Coaxial cable with characteristic impedance of 50 Ω with BNC
connector (RG-58A/U, etc.)
Cable length limit 1 m or less between units, total length of 3 m or less
Maximum number ofconnectable units Connection method 1: 6 units including master unit
Connection method 2: 4 units including master unit
Phase synchronization operation Manual operation
Time difference between units
Delay of each channel of nth slave unit in relation to each channel of the master unit (1
≤ N)
Connection method 1:
31 ns + (N - 1) x 6 ns ± 25 ns or less typ.
Connection method 2:
31 ns + (N - 1) x 31 ns ± 25 ns or less typ.
Condition: Same frequency, same phase, same wave-form (sine or
square), length of connection cable between frequency
reference output and external frequency reference
input = 1 m (RG-58A/U)
