On signal generators with Option 1EM, this connector is located on the rear panel.
34. DATA CLOCK
This female BNC input connector is CMOS compatible and accepts an externally supplied data–clock
input signal to synchronize serial data for use with the internal baseband generator (Option 601/602).
The expected input is a 3.3 V CMOS bit clock signal (which is also TTL compatible) where the rising
edge is aligned with the beginning data bit. The falling edge is used to clock the DATA and SYMBOL
SYNC signals. The maximum clock rate is 50 MHz. The damage levels are > +5.5 V and < −0.5V. The
nominal input impedance is not definable. On signal generators with Option 1EM, this connector is
located on the rear panel.
35. DATA
This female BNC input connector (Options 601/602 only) is CMOS compatible and accepts an
externally supplied serial data input for digital modulation applications. The expected input is a 3.3 V
CMOS signal (which is also TTL compatible) where a CMOS high = a data 1 and a CMOS low = a data
0. The maximum input data rate is 50 Mb/s. The data must be valid on the falling edges of the data
clock (normal mode) or the on the falling edges of the symbol sync (symbol mode). The damage levels
are > +5.5 and < −0.5V. The nominal input impedance is not definable. On signal generators with
Option 1EM, this connector is located on the rear panel.
36. Q Input
This female BNC input connector (E8267D only) accepts the quadrature–phase (Q) component of an
externally supplied, analog, I/Q modulation. The in–phase (I) component is supplied through the I
INPUT. The signal level is
impedance is 50 or 600 ohms. The damage level is 1 V
