Model 4045
Graphical LCD Display
The model 4045 is a must have for anyone needing a feature
packed precision generator. A menu-driven front panel operation
with an easy-to-read graphic LCD display makes the 4045 easy to
operate. Parameter changes and data entry can be made using
the rotary knob or via the build-in RS-232C interfaces. Waveform
editing can be done from scratch or by modifying standard
waveforms.
The 4045 can generate standard or user-defined waveforms with
crystal controlled sampling rates of up to 20MHz, 12 bit vertical
resolution and up to 1,000 points. All waveforms are internally
generated with amplitudes to 10Vp-p into 50ohm. An offset
generator allows generation of signals with large offsets. A full
range of triggering capabilities is available, including
internal-external trigger source, gated and burst modes of
operation.
