Block diagram Master output card
Master outputs
Four per Master output card. Up to two Master output cards per option carrier card. All
mainframe slots can be filled with option carrier cards. Each mainframe needs at least one
acquisition card.
Mainframe to mainframe phase shift
±
150 ns RMS; measured on analog signals using identical acquisition modules, identical
sample rates and filter settings in each mainframe
LED signaling
Optical link synchronized, not connected, function disabled
Master mode
Basic and extended synchronization supported; four Slaves per Master output card
Two Master output cards per option carrier card, multiple option carrier cards per mainframe
Slave mode
Not supported. Use Master/Slave synchronization connector of mainframe for Slave mode.
Maximum mainframes
GEN3i and GEN3t : 16 Slave mainframes, 17 including Master mainframe
GEN7i and GEN7tA : 48 Slave mainframes, 49 including Master mainframe
GEN17tA : 128 Slave mainframes, 129 including Master mainframe
Time required to full synchronization after Master/Slave signal detected
No recording active
1 minute typically
Recording or pause active
1 minute plus 25 s per ms recording time deviation from Master time
User notifications while recording
Time marks on Master/Slave signal lost/restored and Master/Slave time synchronized
Basic synchronization
Cable length propagation delay
±
5 ns/m; Automatic cable length detection and propagation delay compensation
First sample
Synchronizes the first sample in a continuous recording for each mainframe. First samples
are not recorded in the Slave mainframes defined by the cable length propagation delays.
Signal phase shifts are not introduced by this propagation delay.
Synchronized time base
Prevents frequency drift of the sample rates within each mainframe
Measured channel trigger exchange
Synchronously exchanges measured channel triggers connected to the Master/Slave
trigger bus between mainframes. Typically used for the sweep recording modes.
Compatibility
Basic synchronization features are backward compatible with the GEN series Master/Slave
card option for both Master and Slave modes
