19.9. AM/FM Menu

Audio Volume:

to change the volume press the Audio Volume key and use the up and down keys of the

five way navigator to change the volume level (range 1 to 16).

Audio Filter:

toggles the low-pass audio filter on or off. The filter has a turnover point of around 3 kHz

and is useful for attenuating high frequency interference.

To exit this menu

and return to the home menu press the Back (Home) hard key, or the grey area at

the top left of the menu.

19.10.

Level Menu

Atten. On/Off:

toggles the input attenuator between On and Off and sets the reference level to -20dBm

(On) or 0dBm (Off). N.B. in dBµV mode these reference levels become 87dBµV and 107dBµV.

dBm/dBµV:

toggles the display of levels between dBm (power relative to 1mW into 50 Ohms) and dBµV

(power relative to 1 microvolt into 50 Ohms).

Normal:

the normal level display is 10dB/div allowing the full 80dB display range to be shown. Use this

key to cancel zoom mode.

Zoom/Pan:

this key increases the vertical scale to 5dB/div. Use the up/down keys of the five way

navigator to pan the 40dB window through the 80dB range.

To exit this menu

and return to the home menu press the Back (Home) hard key, or the grey area at

the top left of the menu.

19.11.

Markers Menu

Turn Markers On

- press the centre of the 5-way navigator to turn on each marker. (Note that only M1

or M1+M2 can be displayed - not M2 alone).

Select Marker to be Controlled

- once both markers are displayed, subsequent presses of the centre

key toggles the marker under control.

Note that when both markers are on, only the values for the “marker under control” are displayed, along
with the difference values for the two markers.

This menu controls the settings for demodulated
audio in Zero Span mode, which can be Off, AM, or
FM. The demodulated audio is outputted from the
3.5mm stereo/mono jack socket.

This menu allows the reference level (the level
represented by the top of the graticule) to be
changed by means of a switchable attenuator. It also
allows the display to be vertically zoomed. The
current status is shown within the menu area.

This is not truly a menu as it has no soft keys. Two
markers are available shown by yellow and blue
vertical lines. The frequency and amplitude at each
marker point is displayed below the trace area, along
with difference values. The five way navigator is used
to control the markers as follows:
