The mainframe's timing circuits provide crystal-controlled accuracy
with 100 MHz repetition rates, 1 ns step delay and pulse width
resolution and 25 ps syncing coherence to external triggers. Other
useful operating capabilities such as external drive, external
modulation, impulse, single cycle, CW and double pulse are also
provided.
All functions and parameters of the mainframe can be selected by
easy-to-use front panel manual control by way of self-prompting
menus and pushbuttons that send tactile and audible feedback. In
addition, either RS-232 or IEEE-488 bus inputs can be used for
remote control.
For automatic parameter recall and functional control of the
mainframe, each module contains a non-volatile RAM for managing
up to 10 complete sets of output parameters.

STRETCH YOUR BUDGET
Today's varied pulse generating needs are constantly expanding,
while annual equipment funds often don't grow or are reduced.
Therefore, the usual approach of buying another dedicated
instrument for each new requirement becomes prohibitive. The
Model 6040 provides a far reaching solution to this problem with its
money saving versatility.
This versatility begins with the 6040's multipurpose mainframe and
This versatility begins with the 6040's multipurpose mainframe and
extends with software that efficiently utilizes a growing family of
output plug-ins, each of which fits specific applications with less
expense. It's a combination that lets you meet current and future
test needs with smaller budgets; it even allows switching between
electrical and optical test fields as projects progress or change.
OPERATION OVERVIEW
The mainframe itself is a basic 100 MHz pulse generator and a 1
ns-step digital delay generator. That is, without an installed module
the 6040 provides full rep rate, delay and width control for its TTL
and ECL outputs. Furthermore, the maximum frequency is not
limited to that of the 100 MHz internal clock. Thus, when the 150 ps
transition time 201E Module is used, the 6040 can be externally
driven to 500 MHz. While Models 085, 130 and 155 can be
externally driven to 700 MHz.
Simple menus are provided for the operating modes, timing,
triggering and pulse levels. Modes include Pulse, Impulse, CW and
External Modulation. timing choices cover Delay, Width and Single
or Double Pulse. trigger functions are Internal (rep rate), External
Threshold, External Slope, External Drive and Single Cycle.
Independent level control selects pulse peak and baseline, CW
power and quiescent value for External Modulation. Data can be
entered in scientific notation or in decimal form and conveniently
changed with cursor control. All functions are backed up with RS232 and IEEE-488 programmability. And the instrument can be
externally triggered over either bus.
HIGH ACCURACY AND STABILITY
It is unusual for a 100 MHz pulse generator to offer accuracy better
than 3%. The crystal-controlled 6040 has accuracy of 0.2% for
delay and width and 0.01% for frequency along with superior
stability over time. In addition, the jitter between an external trigger
and output pulse is as low as 25 ps.
INCOMPARABLE EDGE SPEEDS
When the 201E Module is installed, impressive high edge-speed
performance results. The clean output pulses have transition times
of 150 ps or less to 5 V amplitude. These fast edges let you
effectively test circuits with high-speed ECL, GaAs or BiCMOS
components. The 5 V level capability permits evaluating excess
voltage immunity and circuit crosstalk. Pulse top and baseline can
be independently adjusted through a ±5 V range to provide outputs
in either normal, complement or bipolar form. The internal
frequency synthesizer provides accurate repetition rates up to 100
MHz. With delay and width resolution down to 1 ns and its trigger
coherent timing, the 6040/201E combination is both a small step
coherent timing, the 6040/201E combination is both a small step
synchronous digital delay generator and high speed pulse
generator with exceptional edge speeds.
DELAY/GATE GENERATOR OPERATION
The inherent accuracy, low jitter and precise timing of the 6040
mainframe provide dependable synchronous digital delay and
variable gate operation. You can use internal triggers or apply
external triggers to obtain coincident delayed outputs with
adjustable pulse widths from the mainframe's 5 V Pulse Out or ECL
connectors. These pulses have 1 ns and 700 ps rise times. If faster
rise times (150 ps), higher amplitudes (to 300 V) or optical pulses
are needed, simply insert the appropriate module. In the past, you
usually would need a pair of instruments, one for precise timing
and another to provide the specific output characteristics. Now you
can test with a single instrument.
SPEED UP OR CONVERT EXTERNAL SIGNALS
External Drive provides higher operating rates and ability to
transform remote signals. With the 6040/201E, electrical signals
(sine, saw tooth, patterns, etc.) to 500 MHz can be sharpened into
steep (150 ps edge) flat top pulses with widths down to 1 ns.
Optical modules like the Model 130 provide 300 MHz external drive
capabilities by which electrical pulses above a selectable threshold
are turned into light. Optical modules can also convert waveforms
from a function, word or pattern generator into their optical
equivalents at rates to 700 MHz or 1400 Mbps.
FAST PULSES TO 20 V, 300 V OR 900 V (See Model 310H for 900
V Pulses)
With the 202H Module installed, the Model 6040 generates positive
or negative 300 V electrical pulses with 5 ns transition times at
or negative 300 V electrical pulses with 5 ns transition times at
rates to 500 kHz. The 203E produces 20 V pulses with 1.5 ns
transition times to 50 MHz driven by either the 6040's internal PRF
or an external source; the source can be periodic or vary in pulseto-pulse rate and duty factor. The outputs of these modules display
minimal ringing and can be set to obtain very narrow pulse width or
gates.

LIGHT AT 1064 nm
The 106H Module produces 1064 nm light pulses to simulate
Nd:YAG lasers. The pulses can range from 5 to 50 ns in width and
provide up to 50 mW peak power. A thermoelectric cooler is used
to maintain spectral stability.
MORE INFRARED LIGHT
Models 085 (850 nm), 130 (1310 nm) and 155 (1550 nm) cover the
wavelengths used for local area networks, long haul
communications and many other applications. Fast pulse rise times
are ideal for testing detector response. With any of these optical
module/mainframe combinations you can independently set the
pulse baseline and pulse top power levels. Each module also
generates subnanosecond impulses at rates to 100 MHz or CW
light.
USEFUL CURRENT SOURCE
Unique circuit design of the Model 201E provides an extra benefit
that lets it serve as a source of current (pulsed or CW) with built-in
protective transient suppression circuitry. The 201E's high level
output provides up to 100 mA selectable in 0.4 mA steps. It can be
used to drive diode lasers through broad rep rate and pulse width
ranges with either a direct or bias tee hookup. The mainframe can
be set for the 201E to deliver either constant or pulsed current. The
202H is useful for driving high power diode lasers, e.g. 820 and
940 nm. Up to 6 A into 50 ohms can delivered. The mainframe's 5
V output or the 20 V 203E also may be used to drive LEDs and
diode lasers that have suitable power requirements. Application
details are available from BNC.
details are available from BNC.
AN IDEAL TRIGGER SOURCE
Research in such fields as chemistry and physics often requires an
accurate, variable, electrical or optical trigger source--sometimes at
very low rates. In addition to operating to 100 MHz, the Model 6040
can fill even the slowest speed needs with internal rates as low as
an output every 100 seconds (0.01 Hz); or it can be manually
single-shot or remotely bus-triggered. Also ruling many applications
is that delay timing begin with an external trigger pulse instead of
the instrument's internal trigger or sync output. It's then important
that delayed outputs be fully synchronous with the external triggers
so as to exclude timing indeterminancies. This 6040 synchronized
delay capability, its start-trigger versatility and optional choice of
high voltage and optical modules make the instrument adaptable to
virtually any kind of electrical or light-pulse triggering requirement.
While the fast rise times and low jitter from the mainframe and
modules ensure precise time control of the triggered event.
