Flexible Interface
■ The back panel has a 10 MHz reference 
signal input/output. This allows you to
synchronize multiple generators to another
generator or to a lab standard signal.
Precisely adjust the output signal's phase 
with respect to this reference signal
■ Marker pulses (50 Ω TTL output) can 
be output at any point on an arbitrary 
waveform for user-defined durations. This 
lets you synchronize other equipment with 
your arbitrary waveforms. Trigger other 
generators phase-locked to the main 
generator to generate multiple waves 
with precise timing and phase 
relationships, or use the marker pulse 
to trigger a scope to let you view a 
system's response at a precise point

Intuitive User Interface
■ Back-lit LCD panel packs a wealth of 
information into a small space and can 
be easily read in a dark environment
■ Intuitive layout of panel and screen 
menus
■ Make parameter adjustments with an 
analog-style knob -- or enter numbers 
directly using the keypad. Enter 
frequency or period, whichever is more
convenient. Use Vpp, Vrms, or dBm for 
amplitude (4076/4079). Left-right arrow 
keys let you choose which digit to 
adjust with the knob
Features & Benefits
■ Both channels offer full functionality. 
All waveform parameters such as 
frequency, amplitude, and offset can be 
set independently
■ Synchronize both output signals to the 
same clock signal (external or internal) 
and precisely adjust the phase 
relationship between the two signals
■ Economical baseband I/Q signal source
■ Saves costs and bench space
Dual Channel Models (4078 & 4079)
Model 4079 (rear view)
This feature of our 407x series 
allows users to generate a posi-
tive TTL level output signal at a
specified point in an arbitrary
waveform. Useful for applications
requiring signal synchronization.
