HP’S NEW TIME INTERVAL MEASUREMENT SOLUTION
The HP 1726A Time [nterval Oscilloscope is a new time interval measuring instrument. Time interval counter (
and oscilloscope technologies have been synergistically combined in the 1726A to offer performance,
convenience, and value unmatched by alternative instrumentation. The contributions of the Time Interval
Oscilloscope benefit users with frequently encountered timing applications and/or precise timing
measurement requirements.
The requirement for stringent timing measurements has resulted from advances in IC design, device
characterization of custom integrated circuits (e.g., bipolar and MO5 processes), ECL circuits, and faster
clock speeds in computers and other electronic systems. For example, characterizing a’process, verifying
system operation, or troubleshooting a new design all require highly accurate and repeatable measurements.
The feature set of the 1726A provides advanced performance with simple setup and the front panel
conveniences expected from Hewlett-Packard products,
“THE COMPLETE TIME
INTERVAL SOLUTION”
Completing the time interval
$olution i$ the I-IF’ 10326A Time
Interval Standard, a dual channel
signal source. The 10326A’s
waveform period accuracy (+/-5
picoseconds) and specified dual-
channel timing relationships
provide convenient signals with
which to evaluate system
performance and subsystem
design. The 10326A is
exceptionally easy to maintain,
and its calibration procedure is
completely traceable to the
United States National Bureau of
Standards and to the calibration
facilities of other International
Standards Organization
members.
FAST, CONFIDENT
MEASUREMENTS
Combining a CRT with a marker
system makes the measured
interval easy to identify. Matched
wideband pre-amplifiers allow
pulse parameters such as
overshoot and ringing to be
examined, and the overlap mode
permits precise measurements to
be made from specific points on
any displayed waveform. This
measurement system eliminates
uncertainty concerning the exact
interval being measured, and it
obsoletes the technique of
externally gating a time interval
counter with an oscilloscope.
PRECISE MEASUREMENTS
(+/-50 PICOSECONDS)
Time interval averaging, which is
automatically controlled through
the Main Time/Div switch, allows
the 1726A to make precise
measurements on virtually any
repetitive signal that can be
displayed on an oscilloscope. A
crystal-referenced time base
combines with sophisticated
triggering circuits to form the
most accurate measurement
system available today-up to 10
picosecond resolution and 50
picosecond
accuracy.
REPEATABILITY AND
CONVENIENCE
Complex time interval
measurements are highly
repeatable and easy to make with
the 1726A’s triggered mode of
operation. The triggered mode
minimizes setup time, simplifies
measurement procedures, and it
allows highly repeatable
measurements to be obtained
-.
independent of the operator’s
skill level. The fast mode, which
reduces the,number of averages
taken by a factor of ten,
minimizes measurement time in
all operating modes. In
production and record-keeping
ap’plications, a standard HP-IB
interface outputs time interval
information.
TWO INSTRUMENTS IN ONE
The feature set of the 1726A
Time Interval Oscilloscope
provides the performance of two
complete instruments. Not only
is the 1726A the most advanced
time interval measurement
solution, but with its time
interval module turned off, the
1726A offers all the capabilities of
