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.

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

When smoke rises from the R3267 Series, smell nastily, o r rear unusual sound feel, turn off the power switch. Pull out power cable from the outlet. And contact to our company.

The address and the telephone number of our company are in the end of this manual.

(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).

1.6 Cleaning, Storing and Transporting the R3267 Series

1.6.1 Cleaning

Remove dust from the outside of the R3267 Series by wiping or brushing the surface with a soft cloth or small brush. Use a brush to remove dust from around the panel keys. Hardened dirt can be removed by using a cloth which has been dampened in water containing a mild detergent.

CAUTION:

1. Do not allow water to get inside the R3267 Series.

2. Do not use organic cleaning solvents, such as benzene, toluene, xylene, acetone or similar compounds, since these solvents may damage the plastic parts.

3. Do not use abrasive cleaners.

• Removing the Display Filter

Normally cleaning the display filter from the front shou ld be sufficie nt. However, if the inside of th e filter or the LCD surface is dirty, you can detach the screen filter from the R3267 Series by removing the two screws on the front and pulling the right-hand part of the filter forward. Clean the filter with a piece of soft close.

CAUTION Do not touch the LCD display with your finger when the fi lter has been removed.

Example 2: The following example sets the reference level to 0 dBm using the step keys:

Press the step key following Example 1. This sets the reference level to -10.0 dBm. If you press the step key once more, the level is set to 0.0 dBm.

• Entering Data Using the Data Knob The data knob is used to set data in increments smaller than the step size. This is convenient

when making fine adjustments to data already entered.

Example 3: The following example sets the reference level to 0.5 dBm using the data knob.

Turning the data knob clockwise increases the reference level in increments of 0.1 dB. Continue to turn it until the active area shows a setting of 0.5 dBm. Turning the data knob counter clockwise decreases the reference level by 0.1 dB.

(3) Soft menu configuration

Menus consist of the main menu, associated submenus and dialog boxes. In addition, there are some soft keys with which you can switch the setting each time you press them. In this section, the menus associated with the

2.2.3 Measuring Frequency Using Counter

Frequencies are measured using the counter function. Use the CAL signal of the analyzer as input signal. The counter function measures the signal frequency at the marker with high accuracy. The value of an amplitude indicates the amplitude at the marker point. The maximum resolution possible for the counter function display is 1 Hz. As you increase the resolution, you will have to increase the gate time to compensate.

CAUTION:

1. The counter function may not work normally if the span is greater than 1 GHz or the difference between the marker and the noise level is 25 dB or less.

• Make the resolution bandwidth (RBW) wider.

• Make the video bandwidth (VBW) wider.

• Make the sweep time (SWP) longer.

• Make the frequency span (SPAN) narrower when the RBW or VBW cannot be changed.

CAUTION: Measured data may be inaccurate if you take measurements while the UNCAL message is dis-

played.

Measurement conditions: The signal to be measured consists of the signal specified below.

Signal 1: A frequency of 900 MHz, a Level of 0 dBm, a pu lse width of 1 msec

and a pulse period of 10 msec.

Signal 2: A frequency of 1800 MHz, a Level of 0 dBm, a pulse width of 1

msec and a pulse period of 10 msec.

Use appropriate parameter values when making the measurements in the example shown below.

Setup

1. Connect the unit under test as shown in Figure 2-68.

2.2.13 Calibration

Calibrations are required to take measurements within the specifications of the analyzer.

CAUTION:

1. Wait 60 minutes after turning the power on before performing the calibrations.

2. If a calibration is performed during the first 10 minutes after the power is turned on, spectrum analyzers with OPT 23 installed may occasionally display error messages since the reference frequency source is not stable.

There are three methods to calibrate the analyzer as shown below.

•Cal All

Performs calibrations for all items to see if they meet the specifications. Perform them before taking measurements. Processing time: Approximately 9 minutes.

•Total Gain

Performs calibrations with more accuracy than Cal All, because user-d efined measu rement conditions are used. Set the conditions first before the calibrations. Processing time: Approximately 1 minute.
