∗
∗
: Can convert to BNC by connecting AUX Conversion Adapter (J1556A).
Input Level
TTL Level
Input Signal
Data, Clock, Enable
Input Bit Rate
100 bps to 10 Mbps
Measured Patterns
PN9, PN11, PN15, PN20, PN23, ALL0, ALL1, Alternate (0101 ...)
PN9Fix, PN11Fix, PN15Fix, PN20Fix, PN23Fix, User Define (4096 bits Max.)
Synchronization
Establishing Condition
PN Signal: PN stage × 2 bit error free
At PNFix Signal: PN stage × 2 bit error free, PN signal and sync establishment, establish sync with PNFix signal at PN stage
error free from PNFix signal header bit
ALL0, ALL1, Alternate (0101 ...): 10 bit error free
UserDefine: 8 to 1024 bits (variable) error free
Select header bit used at sync detection
Re-synchronization
Judgment Condition
x/y (Resynchronization at detection of x-bit error in y bits)
y … Measured bit count: Select from 500 bits, 5000 bits, 50000 bits
x … Number of error bits in y bits: Setting range 1 to y/2
Measured Bit Count
