Kathrein MSK 33 manual Measurement of the amplitude of the video signal, Selecting the video line

Scope Menu

rflev +0dB

sample 1

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 Vpp. The scale is divided in 0.2 V/units.
