DESCRIPTION
1-5.
The standard 5328A mainframe measures frequency, period, period average, time interval,
time interval average, and ratio. A totalize function is also provided. The capabilities of the
instrument are expanded (as shown in Table 1-3) by installing the options described in paragraph
1-17. The 5328A provides an 8-digit (9 with Option 030) LED display, display storage, and leading
zero blanking. Decimal point and unit readouts are displayed automatically. Two independent
selectable input channels are provided for time interval measurements.
Each input channel has
an attenuator, trigger slope selector, level control, ac-dc coupling, and an oscilloscope marker
output. Rear panel connectors provide a gate output, a time base output and an input for an
external frequency standard. An ARM switch on the rear panel allows arming by the signal being
measured (switch OFF) or by another input signal (switch ON).

INSTRUMENT IDENTIFICATION
1-7.
Hewlett-Packard instruments have a 2-section, 10-character serial number (0000A00000),
which is located on the rear panel. The 4—digit serial prefix identifies instrument changes. If the
serial prefix of your instrument differs from that listed on the title page of this manual, there are
differences between this manual and your instrument. Instruments having higher serial prefixes
are covered with a "Manual Changes" sheet included with this manual.
If the change sheet is
missing, contact the nearest Hewlett-Packard Sales and Service Office listed at the back of this
manual.
