Instrument Location and Rack Mounting Requirements
Instrument Location and Rack Mounting Requirements
Locating the Analyzer
Make sure that the fan inlet and exhaust vent areas on the sides of the analyzer
are not obstructed. The minimal required clearance is 2 inches. Airflow
restrictions cause additional airflow noise and cause the fans to speed up so
they can draw in enough air for the required cooling. This results in excessive
audible noise.
Cooling and Rack Mounting
Do not rack mount the analyzer side-by-side with any other instrument with
side-by-side ventilation. Make sure the exhaust air from the first instrument is
directed away from the inlet of the second unit. If the pre-heated air from the
first instrument is directed into the second instrument, it can cause excessive
operating temperatures in the second unit and can cause instrument failures.
When facing the rear panel, the analyzer draws air in from the left side and
exhausts air from the right side.
More than one person is required to lift or carry this instrument.
Alternately a mechanical lift can be used to eliminate the risk of
personal injury.
Safety of any system incorporating the equipment is the responsibility
olf the assembler of the system.

Quick Start
Instrument Information
If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal condition
(in which all means for protection are intact) only.
Install the instrument so that the detachable power cord is readily identifiable
and easily reached by the operator. The detachable power cord is the
instrument disconnecting device. It disconnects the mains circuits from the
mains supply before other parts of the instrument. The front panel switch is only
a standby switch and is not a LINE switch. Alternatively, an externally installed
switch or circuit breaker (which is readily identifiable and is easily reached by
the operator) may be used as a disconnecting device.
Protecting Against Overpowering
The input circuitry of the analyzer can be damaged by applying signals that
exceed the maximum safe input level of +30 dBm average total power or +/-
0.2 Vdc (when DC coupled) or +/- 70 Vdc (when AC coupled). If the instrument
signal path is set to Full Bypass, the maximum safe input level is reduced.
Refer to the analyzer's specification guide for more details regarding the
Maximum Safe Input Level. Repairing damage to the input circuitry can be
expensive.
If the analyzer will be used to measure signals which might be near the
maximum safe input level, use external attenuators and/or limiters to help
protect the analyzer input. The External Gain, amplitude Corrections, and/or
Ref Lvl Offset features may be used to compensate for the gains and losses of
external devices. External Gain and Corrections are under the Input/Output
menu and Ref Lvl Offset is under the AMPTD Y-Scale menu.

Instrument Information
Protecting against electrostatic discharge
Electrostatic discharge (ESD) can damage or destroy electronic components
(the possibility of unseen damage caused by ESD is present whenever
components are transported, stored, or used).
Test Equipment and ESD
To help reduce ESD damage that can occur while using test equipment:
Do not use these first three techniques when working on circuitry with a voltage
potential greater than 500 volts.
— Before connecting any coaxial cable to an analyzer connector for the first
time each day, momentarily short the center and outer conductors of the
cable together.
— Personnel should be grounded with a 1 MΩ resistor-isolated wrist-strap
before touching the center pin of any connector and before removing any
assembly from the analyzer.
— Be sure that all instruments are properly earth-grounded to prevent
build-up of static charge.
— Perform work on all components or assemblies at a static-safe workstation.
— Keep static-generating materials at least one meter away from all
components.
— Store or transport components in static-shielding containers.
— Always handle printed circuit board assemblies by the edges. This reduces
the possibility of ESD damage to components and prevent contamination of
exposed plating.
Additional Information About ESD
For more information about ESD and how to prevent ESD damage, contact the
Electrostatic Discharge Association (http://www.esda.org). The ESD standards
developed by this agency are sanctioned by the American National Standards
Institute (ANSI).

"blue" USB connector, you should connect it to a USB connector with a blue colored
insulator to ensure that it works as advertised.

Display Features
This section describes the regions of the display.
Invalid Data Indicator
The invalid data indicator is displayed whenever the data on the display
does not match the settings of the analyzer. The most common example
of this is when instrument settings have changed in the time since the data in
the traces on the display was taken. This means that the screen annotation
cannot be guaranteed to match the trace data. For example, if you change
Center Frequency, the invalid data indicator will display until a new sweep has
completed.
If any Trace is in View mode (displaying but not updating) and analyzer settings
are changed, the invalid data indicator will display as long as that trace
remains in View. Traces that are blanked do not turn on the invalid data
indicator.
Not all analyzer settings require display of the invalid data indicator when they
change, only changes that require a new acquisition will cause it to display.
For example, changing the Y-Axis scale of the analyzer does not cause the
invalid data indicator to display, unless the attenuation changes.
Also, the invalid data indicator is turned on:
— When the counter is turned on, until the completion of the first count

— When a trace is imported from mass storage and the trace’s parameters do
not match the current analyzer settings
— When a trace is sent to the analyzer from a remote interface (since there is
no way to know if its settings match)
The Data Invalid Indicator has an associated status bit that can be checked at any time
to see if it is on.
Screen Tabs
Along the top of the display are tabs, one for each measurement screen you
have defined. Tap the icon to create a new tab as a "clone" of the current
measurement, which can be changed once it is created:
Tap the current screen tab (or press the Mode/Meas hardkey) to display the
following dialog:
This dialog allows you to choose a Mode, Measurement and View.
When you select a mode, the measurements that are available in the mode are
displayed in the Measurement column.
When you select the desired measurement, the views available for the
measurement are displayed under the View column.
