Flip Down Stand
The metal flip down stand beneath the front panel can be used to provide a better viewing angle.
Use the instrument with the flip down stand opened all the way.
Insert this end into the h ole
(for both sides).
Be sure to support the analyzer firmly with one hand when opening or closing the stand.
Note the following when using the flip down stand:
Use the analyzer on flat surfaces so that the weight of the analyzer is evenly distributed.
• Do not put any objects on the analyzer.
• Do not lean on the analyzer.
• Do not place anything under the analyzer.
• Do not slide the analyzer.
• Do not use excessive force when pressing keys.
• Do not use the analyzer on a slippery place.
• Do not use the wire flip down stand as a carry handle.
• Never drag the instrument or push it from behind when the flip down stand is opened because the
stand may close shut and jar the instrument..
Cautions-1

Other Information for the R3267 Series
Make sure the flip down stand is folded shut when:
• The spectrum analyzer is not in use.
• Connecting or disconnecting cables
• Using the analyzer on a cart
CAUTION:
1. Make sure that the flip down stand is in the normal position when the instru ment is used with the flip down stan d
swung open.
2. Make sure that the instrument is used according to the instructions presented in this section and be careful not
to catch your fingers when opening or cl osing the stand.

1.3 Operating Environment
1.3 Operating Environment
This section describes the environmental c onditions and power requirements n ecessary to u se the R326 7 Series.
1.3.1 Environmental Conditions
The R3267 Series should be only be used in an area which satisfies the following conditions:
• Ambient temperature: 0°C to +50°C (operating temperature)
• Relative humidity: 85% or less (without condensation)
• An area free from corrosive gas
• An area away from direct sunlight
• A dust-free area
• An area free from vibrations
• A low noise area
Although the R3267 Series has been designe d to withstand a certain amoun t of noise ri ding on the A C
power line, it should be used in an area of low noise. Use a noise cut filter when ambient noise is
unavoidable.
• An area allowing unobstructed air flow
There is an exhaust cooling fan on the rear panel and exhaust vents on both sides and the bottom
(toward the front) of the R3267 Series. Never block the fan and these vents.
Keep the rear panel 10 centimeters away from the wall. In addition, do not use the R3267 Series
upright turned the rear panel side down. The resulting internal temperature rise will affect measurement accuracy.

• Use a noise cut filter when there is a large
amount of noise riding on the power line.

1.3.2 Power Su pply Specifications
The R3267 Series can be used safely under the following conditions:
• Altitude of up to 2000 m
• Installation Categories II
• Polluti on Degree 2
1.3.2 Power Supply Specifications
The power supply specifications of the R3267 Series are listed in Table 1-3.
Table 1-3 Power Supply Specifications
100 VAC Operation 220 VAC Operation Remarks
Input voltage range 90 V to 132 V 198 V to 250 V Automatically switches
Frequency range 48Hz to 66Hz
Power consumption 300 VA or below
between input levels of
100 VAC and 220 VAC.
CAUTION To prevent damage, ope rate the R3267 Series within the specified input voltage and freq uency
1.3.3 Power Fuse
CAUTION:
1. When a fuse blows, there may be some problem with the R3267 Series. Contact a sales representative before
replacing the fuse.
2. For fire prevention, use only fuses with the same rating and same type.
The power fuse is placed in the fuse holder which is mounted on the rear panel. A spare fuse is located in
the fuse holder.
To check or replace the power fuse, use the following procedure:

switch (on the rear panel) to the OFF position.
3. Disconnect the power cable from the AC power outlet.
4. Remove the fuse holder on the rear panel (See Figure 1-2).
5. Check (and replace if necessary) the power fu se and put it back in the fuse holder.

3-pin power cable
CAUTION:
1. Use a power cable rated for the voltage in question. Be sure however to use a power cable conforming to safety
standards of your nat ion when using a product overseas (See Table 1-2).
2. Be sure to plug the power cable into an electrical outlet which has a safety ground terminal. Grounding will
be defeated if you use an extension cord which dose not include a safety ground terminal.
3. Turn the MAIN POWER switch (on the rear panel) and the POWER switch (on the front panel) off prior to
connecting the power cab le.

1.4 Precautions in Use
1.4 Precautions in Use
(1) Before starting the measurement
When turning on the power, don’t connect DUT.
Before starting the measurement, check to see the output power level.
(2) Removing of case
Do not open the case to one except service man of our company.
The R3267 Series has a high temperature part and a high pressure part.
(3) When abnormality occurs

(4) Electromagnetic interference.
Electromagnetic interference may be caused to the television or the radio.
If the R3267 Series power is turned off and the electromagnetic interference is reduced, then the
R3267 Series has caused the problem.
Prevent electromagnetic interference by the following procedure.
• Change the direction of antenna of the television or the radio.
• Place the R3267 Series the other side of the television or the radio.
• Place the R3267 Series away from the television or the radio.
• Use another line of power source for the television or the radio than the R3267 Series.
(5) Prevention of Electrostatic Buildup
To prevent damages to semiconductor parts from electrostatic discharg e (ESD), the precautions
shown below should be taken. We recommend that two or more measures be combined to provide
adequate protection from ESD. (Static electricity can easily be built up when a person moves or an
insulator is rubbed.)
Countermeasure example
Human body: Use of a wrist strap (see Figure 1-4).
Floor in the work area: Installation of a conductive mat, the use of conductive shoes, and
grounding (see Figure 1-5).
Benchboard: Installation of a conductive mat and grounding (see Figure 1-6).
