Finally, you must program the
Rotation Time (Sec):
, and this may
take some planning. Many of the 541 alarms have
Time On
(Sec):
and
Time Off (Sec):
settings that will impact your
Rotation
Time (Sec):
choice. See the
Alarms
discussion beginning on Page
34.
The
Status:
display gives a second-by-second countdown of ro-
tation time or shows that the feature is
Off
.
Keep in mind
that all the audio outputs will reflect StationRota-
tion operation. Ask yourself, “Who might be hearing this?”
METERS
The
Meters
Webpage displays metering for all FM signal meas-
urements. From the front panel, the
Meters
menu will offer
multiple sub-screens to accommodate this plethora of readouts.
FM Carrier
Modulation
These three bargraphs and their associated numerical readouts
on the right give quasi-peak-response measurement of FM car-
rier deviation.
Total
modulation and individual
Pos
and
Neg
de-
viation are shown in percent, 100% equal to ±75kHz deviation.
The integration time for these measurements is set by the
Mod
Response:
buttons on the Webpages and LCD-touchscreen
Setup
/ Radio
screens. The default selection is the fastest,
50µs
set-
ting, but more instantaneous-peak-forgiving selections of
100µs
,
200µs
,
500µs
and
1ms
are also available. We recommend the
more conservative default value, but it’s your call.
You should typically see negligible difference between positive
and negative deviation readings, reflecting only the asymmetry
