So far, our examples were only using the provided frequency presets available

at key 2 (45-65Hz). However, you can also make a manual, highly precise fre-

quency range (sweep) adjustment:

However, you can also make a manual, highly precise frequency range (sweep)

adjustment. This way, you can set a frequency range exactly tailored for a spe-

cific signal source in order to measure only this single source.

To set the frequency range, you simply need to know the start and stop fre-

quencies of the subject to be measured and provide them to SPECTRAN.

can find an excerpt from the start and stop frequencies of various signal

sources in the frequency table on page 56.

Manual adjustment

In the following paragraphs, you will find an explanation of such a manual mea-

surement, using a TV set or computer monitor as an example. Proceed as fol-

lows:

First of all, have a look at the frequency list on

derive that TV sets or computer monitors work in the frequency range from

approx. 31kHz to 56kHz. We choose a slightly more liberal frequency range of

20kHz to 70kHz. These are the searched start and stop frequencies which you

have to set as follows:

6.0 Manual frequency selection

At the keys 1 - 5 are different presets available including

the optimal frequency selection for traction power

(16.7Hz), mains power (50Hz/60Hz), harmonics, TFTs,

switching power supplies and others.

Usually these are the measurements which almost any-

body wants to carry out. The amateur in particular will

appreciate these presets, as all frequency parameter are

There are two ways for setting up the requested frequen-

cy range exactly. You can either go in the menu to the
