General Information

APPLICATIONS
1-9.
Specific applications information is provided in Section IV. The general application
features of the 5328A are described in the following paragraphs.
1-10.
The high sensitivity, frequency range, and signal conditioning controls (see Table 1-3)
make the 5328A ideally suited for a wide range of applications. The direct count feature of the
5328A means that prescaling techniques are not used to achieve the 100 MHz frequency range (up
to 512 MHz with Option 030). Direct count speed is required in high-speed totalizing or system
applications. The dynamic range, input attenuators and trigger level range (see Table 1-3) permit
measurements to be made on virtually any signal.
1-11.
The controlled "arming" feature of the 5328A is useful in applications such as burst fre-
quency measurements, and pulse amplitude measurements.
1-12.
The optional integrating digital voltmeters measure trigger levels (critical in most time
interval measurements) and external voltages. The hysteresis compensation feature of Option 040
means that the trigger level does not need resetting when the slope switch cha ges the polarity.
1-13.
The standard 5328A single-shot resolution of 100 ns meets the requirements for appli-
cations such
as mechanical
and electromechanical
device (relays) timing, time of flight
measurements (ballistics), sonar ranging, radio ranging and navigation. The Option 040 provides
increased resolution (to 10 ns) useful in applications such as computer/peripheral timing mea-
suremnts, logic timing measurements, radar ranging and optical ranging. The delay feature of
Option 040 allows unwanted signals to be ignored which would otherwise trigger the counter.
1-14.
Using time interval averaging, time intervals as short as 100 ps, with resolution to 10 ps may
be measured. Applications include cable length measurements, phase measurements, logic
timing measurements, and integrated circuit propagation delay measurement.
1-15.
Full bandwidth, sensitivity, and signal conditioning of the Channel A,B (andC
for Option
030) input amplifiers is provided for ratio, totalizing, and scaling measurements.
1-16.
The 5328A with Option 011 HP-IB Interface is able to output measurement data and be
controlled (fully programmed) via the Hewlett-Packard Interface Bus (HP-IB). The 5328A is
interfaced to HP-IB compatible instruments, calculators, or computers by simply interconnecting
with an HP-IB cable.
1-17.
OPTIONS
1-18.
Several options are available with the 5328A, as listed below. If purchased as part of an
initial order, options are installed at the factory and the instrument is ready for operation when
received.
Procedures for field installation of an option are described in the Installation and
Service Manual supplied with each option (except for Option 010, Oscillator which is covered in
the 5328A Service Manual).
The following options are available:
a.
Option 010, High Stability Time Base. Oven oscillator with aging rate <5 x 10-1°/day.
b.
Option 011, HP-IB Interface. Allows 5328A to output data and be controlled via the HP
Interface Bus.
c.
Option 020, Digital Voltmeter (DVM). Single ended DVM for trigger level and external
dc voltage measurements.
d.
Option 021, High Performance DVM. Floating high accuracy DVM for trigger level and
external dc voltage measurements.
