• The relative level can also be taken to be a relative
voltage level, regardless of whether the level is displayed
in dB or dBm. The numerical value is not adjusted when
you switch from dB to dBm or vice versa.
• It is only possible to define one relative level at any one
time. However, up to 100 setups (and hence up to 100
reference levels) can be stored using the "STO MEM"
facility.
Fig. 4-21 Selective level measurement in dBm0. Row D shows the
relative level in dBr(REL). It is entered by pressing [*]
and [dBm0]. The receiver can be precisely tuned to the
input frequency using the up / down keys.
4.2.6 Bargraph, AVRG, MAX. HOLD
4.2.6.1 Bargraph
The instrument has a bargraph that has certain similarities
with an analog meter. The eye can interpret changes in the
length of the line more rapidly than changes in a purely
digital display.
