Measurement Possibilities
Level measurement
The MSK 33 is designed for the level measurements on receiving systems in the measuring range of 30 dBµV to 130 dBµV. The level measurement is automati- cally carried out after connecting the unit and setting a frequency and is displayed on the display screen. The table shown below represents a brief overview of the measurement possibilities of the MSK 33.

Maximal input level
The maximal measurable input level of a carrier, which can be measured with the MSK 33, is 130 dBµV. If a system with several carriers or programmes is meas- ured, the maximal total capacity of all carriers determines the admissible input level. The
The following table serves to approximately determine the maximal total capacity. It only applies, if all the carriers contain the same level. When the carriers are dou- bled, the maximal input level of the MSK 33 is reduced by 3 dB, refer to the table below.
Number of the fed- | Reduction | Maximal input level, if all carriers con- |
in carriers |
| tain the same level |
4 TV programmes |
| 129 dBµV |
9 TV programmes | 126 dBµV | |
18 TV programmes | 123 dBµV | |
36 TV programmes | 120 dBµV |
Exceeding the maximal input level may damage the input stages or the unit! Intermodulation and overcontrol effects can occur for each maximal admis- sible assignment!
