Keysight E4990A Impedance Analyzer

Installation Guide

1 Introduction

This chapter provides information about how to set up Keysight E4990A

Checking the Shipment

After you receive the analyzer, carry out checks during unpacking according to
the following procedure.

When unpacking the analyzer, if the exterior of the analyzer (such as the
cover, front/rear panel, LCD screen, power switch, and port connectors)
appear to be damaged during transport, do not turn on the power switch.
Otherwise, you may get an electric shock.

Step 1. Check that the packing box or shock- absorbing material used to package the

analyzer has not been damaged.

If the packing box or shock-absorbing material has been damaged, leave
the packing box and shock-absorbing material as is until other inspection
items are checked as follows.

Step 2. Check the packaged items supplied with the analyzer for any damage or

defects.

Step 3. By referring to the furnished contents list, check that all packaged items

supplied with the analyzer have been received as per the specified options.

Step 4. After checking, if one of the following applies, contact your nearest Keysight

Technologies sales and service office.

1. The packing box or shock- absorbing material used to package the analyzer
has been damaged or the shock- absorbing material has traces where
extreme force has been applied.

2. A packaged item supplied with the analyzer has mechanical damage or
defects.

Altitude 0 to 2,000 m (0 to 6,561 feet)

Vibration 0.21 G maximum, 5 Hz to 500 Hz

Above environmental requirements are NOT for the specifications and
measurement accuracy of the analyzer, but for the operating environment
of the analyzer.

Ventilation Requirement

To ensure safety requirements, the specifications and measurement accuracy
of the analyzer, you must keep the environmental temperature within the
specified range by providing appropriate cooling clearance around the analyzer
or, for the rack mount type, by forcefully air- cooling inside the rack housing.
For more information on environmental temperature to satisfy the
specifications and measurement accuracy of the analyzer, see the specification
in the E4990A Datasheet.

23 °C ± 5 °C (< 1 °C deviation from the temperature when

Introduction
Environmental Requirements

Installing Front Handles/Rack Mounting Flanges

The E4990A can be installed on a workbench or on a rack.

This section describes how to install the front handles (Option 1CN) used for
moving or transporting the instrument, and how to install the analyzer in an
equipment rack as part of a measurement system (Option 1CM: without the
handles, Option 1CP: with the handles).

Figure 1-2 Installing front handle/rack-mount kits

14 Keysight E4990A Impedance Analyzer

Introduction
Environmental Requirements

Figure 1-3 E4990A with Option 1CN handle

The handle kit (Option 1CN) is used for transporting and relocating of the
E4990A.

The rack- mount kit (Option 1CM) includes two flanges (locking side plates) for
mounting the E4990A on a rack (482.6 mm/19 inches) conforming to the EIA
Standard.

Option 1CP comes with both, the handle kit and rack- mount kit.

While referring to Figure 1-2 install the handle kit/rack- mount kit by following
these steps.

Step 1. Remove the adhesive- backed trim strip (1) from each side of the outer frame

of the E4990A front panel.

Step 2. Use the provided screws to mount the

• front handles (2) - for Option 1CN

• rack- mounting flange (4) - for Option 1CM

• both - for Option 1CP

on each side of the E4990A front panel frame.

Step 3. (Option 1CN/Option 1CP). Attach the modified trim strip (3) provided to each

front handle in order to cover the front panel locking screws.

Option 1CN contains 2 pieces of standard and 1 special handles ­E4990-20001. Only one of the standard handle is required to be used to
mount on the analyzer. Standard handle is used for the left side and
special handle is used for the right side. Refer to Figure 1-3.

Introduction
Starting the E4990A

Step 2. Next, if necessary, turn OFF the power supply to the power cable receptacle

(Line Switch) on the rear panel.

Under normal use, never directly interrupt the power supply to the power
cable receptacle on the rear panel when the power supply is turned ON.
Always keep the Line Switch ON and never turn it.

If you directly interrupt the power supply to the power cable receptacle
when the power supply is turned ON, or turn OFF the Line Switch, the
shutdown process will not work. This could damage the software and
hardware of the E4990A and lead to device failure.

Turning ON the power supply after a faulty shutdown may cause the
system to start up in a condition called "safe mode." If this occurs, first
shut down the system to set it to the standby state and then turn ON the
power supply again to start up the system in normal mode.
