To call the menu OPERATION MODE, press the button
MENU (repeatedly). Select the desired function using the
button  or  and press the button ENTER to call the
function.

WiFi Analyser: Wifi analyser mode (chapter 5)
This function can only be called if the frequency range
"15 – 2700M" has been selected in the bottom line
"Module" of the frequency menu (chapter 4.2); other-
wise, the message "THIS FEATURE IS NOT AVAILABLE IN
THE SELECTED MODE" will appear. In this case, press the
button ENTER to return to the menu OPERATION MODE.

range (4.8 – 6.1 GHz or 15 – 2700 MHz; chapter 4.2) with

This menu which allows to change frequency settings is
probably the menu most used.
When, after switching-on the RF EXPLORER, the
spectrum is displayed and the button MENU is pressed
twice, the frequency menu appears. However, this pro-

MENU is pressed while the spectrum is displayed, the last

menu called appears. Thus, time is saved as it is not nec-
essary to navigate through all menus to return to the
*
previous one.
There are two different methods to change the frequency
range shown in the spectrum display:
1. Center Freq and Freq Span
This is the usual spectrum analyser adjustment all
experts are familiar with. The center frequency (Center
Freq) of the frequency band to be analysed is adjusted
and then the bandwidth (Freq Span).
2. Start Freq and Stop Freq
Only a few spectrum analysers offer this user-friendly
method. The lower frequency (Start Freq) and the
higher frequency (Stop Freq) of the frequency range
to be analysed are adjusted.
When Center Freq and Freq Span are adjusted, Start Freq
and Stop Freq are changed accordingly and vice versa. In
general, Center Freq / Freq Span are adjusted when the
frequency is known and Start / Stop Freq to check a cer-
tain range.
To go to an option, use the buttons  and . Then press
the button ENTER to be able to edit the option. Go to the
position to be changed with the button  or . Adjust
the desired value with the button  or  and confirm
the adjustment with the button ENTER or cancel it with
the button RETURN.
In the line Module, use the button ENTER to select
the frequency range to be analysed (15 – 2700 MHz or
4.8 – 6.1 GHZ). After selection, the display will briefly in-
dicate the activated frequency range with the antenna
jacks used:

Then the display will automatically return to the frequency
menu.
Notes:
1. The adjustable bandwidth depends on the frequency range
selected:
Reception range
15 – 2700 MHz
4.8 – 6.1 GHz
2. The lowest and the highest frequency to be adjusted
depend on the settings in the menu lines "Freq Span" and
"Module".
Example of a change of bandwidth from 9 MHz to
6.5 MHz; the lower and the higher frequency will be up-
dated automatically:

The new frequency range is adjusted. As a further exam-
ple, repeat the procedure to change the bandwidth to
2.5 MHz. For this purpose press the button MENU again:
The previous menu option (Freq Span) is selected. Change
the value to 2.5 MHz and confirm with the button ENTER.
Then press the button RETURN to return to the spectrum
display.

ELECTRONICS FOR SPECIALISTS
The new frequency range is adjusted but what is interest-
*
ing now is that the center frequency can also be changed
with no need to call the frequency menu. For this purpose
press the button  or  (repeatedly) when the spectrum
is displayed: Each time the center frequency is reduced or
increased by ⅛ of the bandwidth, i. e. at a bandwidth of
2.5 MHz by 0.3125 MHz by just pressing a key. This direct
method is especially useful with a narrow bandwidth.
During the spectrum display the measuring values and
the measuring curve can be frozen by pressing the but-
ton ENTER. This facilitates the reading for values rapidly
changing. In this case, the indication

button ENTER again.

The frequencies of the scan range are indicated at the

When the button  or  is now pressed (repeatedly), it is
not the centre frequency which is changed but the band-
width. Thus, the bandwidth can also rapidly be changed

iterations [sweeps] (see menu option below) are used,
in this case the peak values of the last 4 scans. This

can be found in difficult cases. (The selected mode is
