Easy-to-use functionality
Front-panel operation of the
33220A is straight-forward and
user friendly. You can access all
major functions with a single key or
two. The knob or numeric keypad
can be used to adjust frequency,
amplitude, offset, and other para-
meters. You can even enter voltage
values directly in V
pp
, V
rms
, dBm,
or as high and low levels. Timing
parameters can be entered in Hertz
(Hz) or seconds.
Internal AM, FM, PM, FSK, and
PWM modulation make it easy to
modulate waveforms without the
need for a separate modulation
source. Linear and logarithmic
sweeps are also built in, with
sweep rates selectable from 1 ms
to 500 s. Burst mode operation
allows for a user-selected number
of cycles per period of time. GPIB,
LAN, and USB interfaces are
all standard, plus you get full
programmability using SCPI
commands.
External frequency
reference (Option 001)
The 33220A external frequency
reference lets you synchronize to an
external 10 MHz clock, to another
33220A, or to an Agilent 33250A.
Phase adjustments can be made
from the front panel or via a com-
puter interface, allowing precise
phase calibration and adjustment.
