The following values are displayed on the screen:
Line 6
Time 38 µs – based on the line and is measured in the centre of the
screen.
Signal/noise spacing S/N = 37.5 dB w (weighted)
With this softkey, the input loss can be changed to +4 dB and +8 dB. This in-
creases the measurement dynamic. (Be careful of intermodulation!).
Number of the measuring cycles with averaging (1 to 5 measuring cycles).
Measurement of the amplitude of the video signal
The video level of the fed-in RF signal can also be measured
in the SCOPE menu.
On the scale on the left margin of the screen, the video level
can be read. The scale is divided in 200 mV steps (a secon-
dary graduation line). The position of the video signal can be
changed with the cursor buttons.
Selecting the video line
The video line can be selected with the numerical buttons,
0..9. After entering in a three-digit number, it is automatically
taken over. After entering a one-digit or 2-digit number, the
entry is adopted once you press the Enter button. Scroll
down the video lines with the cursor buttons, ◄ and ►. Here,
it is recommended to switch off the zoom function or set to
the minimal zoom.
Measurement of video signals via the AV socket (SCART)
Via the AV socket (Scart), a video signal can be fed-in and represented on the os-
cilloscope.
To do so, the function CVBS input must be selected in the AV menu. The maximal
input voltage is 2 V
pp
. The scale is divided in 0.2 V/units.
