Carrying out measurements

By pressing this button, the MSK 33 is set to analogue reception and measures the
following values:

- Audio carrier spacing from TT1 (sc1) and TT2 (sc2)

- Nicam audio carrier spacing (if available)

- Nicam bit error rate (BER)

- Minimal and maximal level (min./max.)

Level measurement ANALOGUE

The following displays appear on the screen, when the button, „measure,“ is
pressed.

Measurement of the audio carrier spacing

Audio carrier 1: -13.5 dB
Audio carrier 2: -19.5 dB

Measurement of the Nicam audio carrier spacing and the bit error rate

Nicam audio carrier spacing 1: - 18.5 dB
Nicam audio carrier spacing: 5.6E-06 (5.6

-6

)

Measurement of the min./max. level

In the display, the following values are represented:
Minimal level: 77.5 dBµV
Maximal level: 82.5 dBµV
In this function, the MSK 33 measures the minimal and the
maximal level, so the check points can be tracked for level
fluctuations.

As long as this measurement function is called up, the MSK 33 measures the
minimal level and the maximal level. This measurement function serves for
monitoring the check points for level fluctuations.

Measurement of the current level

In the display appears:
Channel: IF
Frequency: 38.9 MHz
Analogue reception: A
Current level: 79.5 dBµV

An „A“ in front of the level display means, that the MSK 33 has been set to
analogue level measurement. Even after exiting the menu, the MSK 33 stays
set to ANALOGUE reception.

For level measurement on digital IF signals, the MSK 33 can be switched-
over to the digital menu (refer to the respective section).
