Signal Generator Overview
Front 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
=
0.5 V
rms
for a calibrated output level. The nominal input impedance is 50 or
600 ohms. The damage level is 1 V
rms
and 10 V
peak
. To activate signals applied
to the I and Q input connectors, press Mux > I/Q Source 1 or I/Q Source 2 and
then select either Ext 50 Ohm or Ext 600 Ohm . On signal generators with
Option 1EM, these connectors are located on the rear panel.
37. I Input
This female BNC input connector (E8267D only) accepts the in–phase (I)
component of an externally supplied, analog, I/Q modulation. The
quadrature–phase (Q) component is supplied through the Q INPUT. The signal
level is
= 0.5 V
rms
for a calibrated output level. The nominal input
impedance is 50 or 600 ohms. The damage level is 1 V
rms
and 10 V
peak
. To
activate signals applied to the I and Q input connectors, press Mux > I/Q
Source 1 or I/Q Source 2 and then select either Ext 50 Ohm or Ext 600 Ohm .
On signal generators with Option 1EM, these connectors are located on the
rear panel.
