HF38B

RF Analyzer for Frequencies from 800 MHz

to 2.5 GHz

Instruction Manual

It is imperative to carefully study the instruction manual prior

to using the RF analyzer.

Much important information regarding safety, use and mainte-

nance is provided herein.

Professional Technology

With the RF analyzers, GIGAHERTZ SOLU-

TIONS

sets new standards in RF testing.

Professional measurement engineering is of-

fered with a unique price/performance ratio -

the only one of its kind worldwide. This was

made possible through the consistent use of

innovative integrated components, some of

which have patents pending, as well as

highly sophisticated production engineering.

The RF analyzer you purchased allows a

competent assessment of RF exposures be-

tween 800 MHz and 2.5 GHz. From a build-

ing biology perspective, this particular fre-

quency range is especially relevant because

cellular phones, cordless phones, microwave

ovens as well as next-generation technolo-

gies such as UMTS (3G) or Bluetooth all

make extensive use of it.

We appreciate the confidence you showed

when purchasing the RF Analyzer HF35C.

With the confidence that your expectations

will be met, we wish you great success in

collecting useful information with this RF

analyzer.

In addition to this instruction manual, our

partners and we also offer User Workshops

on how to optimize the use of our testing

equipment as well as efficient shielding

strategies.

If you should encounter any problems,

please contact us immediately. We are here

to help you in a professional, efficient and

customer-friendly manner.

Safety Instructions:

It is imperative to carefully study the instruction manual prior to using the RF analy-

zer. Much important information regarding safety, use and maintenance is provided

herein.

The RF analyzer should never come into contact with water or

be used outdoors during rain. Clean the case only from the

outside, using a slightly moist cloth. Do not use cleaners or

sprays.

Prior to cleaning the RF analyzer or opening the case, shut it

off and unplug all extension cords. There are no user-

serviceable parts inside the instrument.

Due to the high sensitivity level, the electronics of the RF ana-

lyzer are very sensitive to heat, impact as well as touch.

Therefore do not leave the instrument in the hot sun, on a

heating element or the like. Do not let it drop or try to manipu-

late its electronics inside when the case is open.

This RF analyzer should only be used for the purposes de-

scribed herein and only in combination with supplied or rec-

ommended accessories.

(See section „Changing Battery“) Battery Voltage Check If the „low-batt.“ indicator appears vertically in the center of the display, measurement values are not reliable anymore. In this case, change the battery. This RF analyzer requires a high-quality alkali-manganese battery with a 9-volt nominal voltage. 9-volt rechargeable batteries are not recommended. Function Testing ances are also met.

Introduction to RF Measurement Tech- nology Polarization When RF radiation is put on the airwaves, it is sent off with a „polarization.“ In short, the electromagnetic waves propagate either vertically or horizontally. Cellular phone technology, which is of greatest interest to us, is usually vertically polarized.

Digitaler Hochfrequenz Analyser HF38B Preparations Prior to Testing Check the RF analyzer and its antenna by following the instrunctions under „Getting Started.“ Connecting the Antenna Screw the angle connector of the antenna connection into the uppermost right socket of the RF analyzer. It is sufficient to tighten the connection with your fingers. (Do not use a monkey wrench because otherwise the thread might break.

Digitaler Hochfrequenz Analyser HF38B mum value. Insofar it is quite possible to have two different readings at the exactly same spot within 24 hours. The maximum value across a locally defined area, however, usually changes only if also the RF sources change, which is why the latter value is much more representative of the assessment of RF exposure. Since this is not an accurate quantitative measurement but a quick overview assessment, the antenna can be removed from the top end of the RF analyzer.

Digitaler Hochfrequenz Analyser HF38B Audio Frequency Analysis Many different frequencies within the frequency band between 800MHz and 2.5GHz are being used by many different services. The audio analysis of the modulated portion of the RF signal helps to identify the source of a given RF radiation. First get the RF analyzer ready for testing, following the instructions in the relevant section.

Digitaler Hochfrequenz Analyser HF38B Warranty We provide a two-year warranty for factory defects on the RF analyzer, the antenna and accessories. Thereafter generous fairness rules will apply. Antenna Even though the antenna appears to be rather delicate, it is made from a highly durable FR4 base material that can easily withstand a fall from a table. The warranty does also include such impact damage if it should ever occur.
