50 MHz Programmable Pulse Generators
Models 4033 & 4034
Description
The 4033 and 4034 are high performance pro-
grammable pulse generators for testing digital
systems and circuits based on TTL, CMOS, or
ECL technologies. Both instruments generate
clean and accurate pulses at up to 6 digits reso-
lution with a repetition rate up to 50 MHz, vari-
able pulse widths from 10 ns to 10 s, and pulse
delays from 0 ns to 10 s. Output levels are
adjustable from -10 V to +10 V, with pulse
amplitudes settable from 0.1 Vpp to 10 Vpp into
a 50 ohm load. All parameters, modes, and
functions are programmable via the front panel
or remote control commands. Additionally, the
pulse generators provide selectable complemen-
tary pulse and double pulse generation in contin-
uous, triggered, gated, and counted burst
modes.

50 MHz Programmable Pulse Generators
Models 4033 & 4034
Industry Leading Performance
External Width
In the external width pulse mode, pulse period
and width are determined by an externally
applied signal. The pulse generator then applies
transition and level parameters to this signal in
order to generate the pulse. A power supply
designer for example could use this feature to
shape the width and period of the output signal
to drive the power supply’s FET transistors while
remaining synchronized with its control circuits.
Variable Transitions
For added flexibility, variable rise and fall times
can be programmed from 6 ns to 100 ms.
Various shapes of pulses can be obtained for
applications where parameters such as linearity,
switching times, or reflection times must be ana-
lyzed. Programmable rise and fall times could be
used to measure operational amplifier slew rates
and easily test thresholds of devices and circuits.
Straightforward User Interface
These generators use a menu-driven front panel
keypad and control knob to adjust all parameters.
The bright, easy-to-read display shows all rele-
vant parameters along with a graphical represen-
tation of the output pulse. If an entered parame-
ter is not compatible with the existing setup sta-
tus, the operator is informed by an error mes-
sage.
Users can conveniently select predefined ampli-
tude levels for TTL, ECL, and CMOS signals, or
choose a custom amplitude level for specialized
applications.
