Softkeys
MIN Starts the MIN-Hold process. Every time this key is pressed the MIN-Hold
process is restarted.
MAX Starts the MAX-Hold process. Every time this key is pressed the MAX-Hold
process is restarted.
AVG Starts averaging according to selection. Each time this key is pressed the
averaging function AVG is started anew. The measured level values are
averaged over the measuring time.
CLRWRITE Activates the CLEAR WRITE function. The currently measured level values are
displayed. Here the measuring time is of no importance.
_|__ TO ^ Centers the spectrum to the next relative level maximum left of the marker when
the squelch is off. When it is on the center frequency is set to the next level
maximum to the left which is above the squelch line.
__|_ TO ^ Centers the spectrum to the next relative level maximum right of the marker
when the squelch is off. When it is on the center frequency is set to the next level
maximum to the right which is above the squelch line.
With switched on squelch the squelch value is indicated as a horizontal line in the spectrum. Thus the
level of the individual frequencies can be measured.
Note:
The level indication of the receiver is identical only in exceptions with the height of the average
spectrum line (for example with a CW carrier). In the case of broad-band signals or noise, differences
up to 20 dB and more occur. This is caused by the different bandwidth with which the level detection is
carried out. The resolution bandwidth of the panorama equals approx. 1/1000 of the set span.
