Atec Wavetek-395 - Manual

3
continuous range from 1 mHz to 20 MHz.
Triggered and manual sweep operations
also can be performed. Seven sweep
modes, with linear and logarithmic sweep
spacing, a TTL level sweep marker, and a
ramp output give you the flexibility you
need. There’s even a pen lift function for
use with chart recorders.
Modulation Source. If you do communi-
cation or audio design and test, Model 395
offers internally generated amplitude
modulation and frequency modulation, as
well as externally controlled amplitude
modulation in two modes.
Convenience and Versatility. Wavetek
designed Model 395 for user convenience.
The user screens are tailored to the
particular jobs you want to perform, such
as setting up a pulse generator or a noise
function.
From any screen, you can access help
screens that guide you in using the
instrument’s extensive capabilities. And
you can store at least 10 instrument set-
ups so you don’t have to spend valuable
time duplicating past effort.
Low cost of ownership is assured by
the high reliability and ease of calibration
of the Model 395. Calibration is performed
with covers on in less than 15 minutes,
under front panel or remote control.
