BANDWIDTH
: 1.23
MHz
]
Set the channel bandwidth to 1.23 MHz in line with IS95.
[
ADJUST SETTINGS
]
Set the optimum span (= 5 MHz), resolution bandwidth
(RBW = 30 kHz), video bandwidth (VBW = 300 kHz) and
detector (RMS) for the measurement automatically. The
absolute channel power and the relative power of the
adjacent channels and alternate channels are displayed
on the screen.
Go to the main menu for channel power measurement
[
ADJUST REF LVL
]
Set the reference level equal to the channel power mea-
sured.
[
SET CP REFERENCE
] Set the measured channel power as a reference for the
subsequent measurements.
[
CP/ACP ABS / REL
]

power set with
SET REFERENCE
(result 0 dB).
[
CHAN PWR / HZ
]
Select power measurement related to 1 Hz bandwidth
(result -60.9 dB).
[
FREQ:
CENTER
: 805
MHz
]
Set the center frequency to 805 MHz. The R&S ESU mea-
sures the channel power at 1.23 MHz bandwidth and out-
puts the result in dB relative to the reference power and 1
Hz bandwidth.
