feedback signal to inhibit pulse
output.
In a Test System …
To achieve high test throughput,
and efficient integration of
diverse test instruments and
effective generation of test
programs, the Agilent 8114A
integrates smoothly into

Clean, Reliable Pulses
The Agilent 8114A generates
clean pulses with low jitter and
excellent pulse performance at all
specified settings in any
triggering mode and, of course,
across the entire operating
temperature range. Parameters
and trigger modes can be changed
without generating unwanted
pulses, so that reliable
measurements are guaranteed
External Synchronization
As well as generating continuous
streams of pulses, the Agilent
8114A can be triggered or gated
by an external signal or the
MANual trigger key.
Combined with the ability to
generate double-pulses per period
and counted bursts you can
generate a variety of pulse
patterns synchronized to an
external signal.
Accuracy and Repeatability
The excellent accuracy,
repeatability and resolution of the
Agilent 8114A let you concentrate
on your results, not the
measurement. Confidence in
your results is assured when you
can trust your test set-up and the
Agilent 8114A maintains its pulse
performance at all specified pulse
amplitudes.
Voltage or Current
With the Agilent 8114A you can
set the pulse levels in terms of
voltage or current, to suit the
device you are testing.
Load Compensation
You can quickly set the pulse
levels for your device, even when
it's not a true 50 W load. Set the
expected load impedance at the
output and the Agilent 8114A
adjusts its signal accordingly to
achieve the required levels as
shown on the display or
programmed via GPIB.
Device Protection
To reduce the risk of accidental
damage to the device under test
the Agilent 8114A has adjustable
voltage, current and duty cycle
limits. As long as the limits are
enabled you cannot set or
program the output signal outside
your chosen limits.
The Agilent 8114A inhibit input
accepts a TTL feedback signal
from your test system or device
under test to inhibit the pulse
signal under hardware control.
Reduced Programming
All parameters of the Agilent
8114A are programmable via
GPIB. SCPI (Standard Commands
for Programmable Instruments)
facilitates the standardization of
test programs and offers a
common programming syntax
with other instruments.
The local user-interface eases the
transition from manual to
automated test by displaying the
SCPI command syntax for each
parameter as part of the onscreen help information.
Easy Rack Integration
Optional rear panel connectors
and rack mount kits make it easy
to install the Agilent 8114A in a
rack-based system.
Conformance to the latest
European EMC standards minimizes radiated and conducted
electromagnetic interference with
the test system.
Reliable measurements are
guaranteed over the whole
temperature range that exists in a
test rack.
Specifications
Specifications describe the instrument's warranted performance. Non-warranted values are described as typical. All specifications apply after a 30-minute warm-up phase with 50 W source/load resistance. All specifications are valid from 0°C to 55°C
ambient temperature.
8114A Specifications
Timing Characteristics
Measured at 50% amplitude at fastest transitions in continuous mode and 50WWsource impedance.
Width: Can be set as width, duty
cycle, or trailing edge delay.
Burst Count: 2 to 65536 (single or
double pulses).
Double Pulse: Two pulses are
generated per pulse period. The
first pulse starts at the start of
the period, the double-delay sets
the delay to the start of the
second pulse. Double pulses are
available in all trigger modes
except External Width.
Delay: Delay, phase or % of period.
Double pulse delay: Double pulse
and delay are mutually exclusive.
The delay between double pulses
can be set as delay or % of period
(minimum period 134 ns)
Duty cycle: Set between 0.1% and
100% (subject to width limits and
period specifications).
Figure 1 shows the specified
operating range for actual duty
cycle and amplitude. Note that in
double pulse mode the actual
duty cycle is twice the displayed
value.
Repeatability: Is typically four
times better than accuracy.
